Detailed Description

Abstract superclass for all arrays.

vtkAbstractArray is an abstract superclass for data array objects. This class defines an API that all subclasses must support. The data type must be assignable and copy-constructible, but no other assumptions about its type are made. Most of the subclasses of this array deal with numeric data either as scalars or tuples of scalars. A program can use the IsNumeric() method to check whether an instance of vtkAbstractArray contains numbers. It is also possible to test for this by attempting to SafeDownCast an array to an instance of vtkDataArray, although this assumes that all numeric arrays will always be descended from vtkDataArray.

Every array has a character-string name. The naming of the array occurs automatically when it is instantiated, but you are free to change this name using the SetName() method. (The array name is used for data manipulation.)

		vtkIdType	j,
		vtkAbstractArray *	source
	)		`[pure virtual]`

Set the tuple at the ith location using the jth tuple in the source array. This method assumes that the two arrays have the same type and structure. Note that range checking and memory allocation is not performed; use in conjunction with SetNumberOfTuples() to allocate space.

Implemented in vtkVariantArray, vtkDataArray, vtkStringArray, vtkDataArrayTemplate< T >, vtkCPExodusIINodalCoordinatesTemplate< Scalar >, vtkCPExodusIIResultsArrayTemplate< Scalar >, vtkBitArray, and vtkUnicodeStringArray.

virtual void vtkAbstractArray::InsertTuple	(	vtkIdType	i,

virtual void vtkAbstractArray::GetTuples	(	vtkIdList *	ptIds,
		vtkAbstractArray *	output
	)		`[virtual]`

Given a list of point ids, return an array of tuples. You must insure that the output array has been previously allocated with enough space to hold the data.

Reimplemented in vtkStringArray, vtkDataArray, vtkMappedDataArray< Scalar >, vtkCPExodusIINodalCoordinatesTemplate< Scalar >, and vtkCPExodusIIResultsArrayTemplate< Scalar >.

virtual void vtkAbstractArray::GetTuples	(	vtkIdType	p1,

If the array does not have the standard memory layout GetVoidPointer should not be used, as a deep copy of the data must be made. Instead, use a vtkTypedDataArrayIterator to get pointer-like semantics that can safely access the data values. Subclasses that return false here must derive from vtkMappedDataArray to ensure that they will work safely with the rest of the pipeline.

Reimplemented in vtkMappedDataArray< Scalar >.

virtual void* vtkAbstractArray::GetVoidPointer ( vtkIdType id ) [pure virtual]

Return a void pointer. For image pipeline interface and other special pointer manipulation. If the data is simply being iterated over, consider using vtkDataArrayIteratorMacro for safety and efficiency, rather than using this member directly.

Implemented in vtkDataArrayTemplate< T >, vtkStringArray, vtkBitArray, vtkVariantArray, vtkMappedDataArray< Scalar >, and vtkUnicodeStringArray.

virtual void vtkAbstractArray::DeepCopy ( vtkAbstractArray * da ) [virtual]

Deep copy of data. Implementation left to subclasses, which should support as many type conversions as possible given the data type. Subclasses should call vtkAbstractArray::DeepCopy() so that the information object (if one exists) is copied from da.

Reimplemented in vtkDataArray, vtkStringArray, vtkBitArray, vtkVariantArray, vtkCPExodusIINodalCoordinatesTemplate< Scalar >, vtkCPExodusIIResultsArrayTemplate< Scalar >, vtkUnicodeStringArray, and vtkMappedDataArray< Scalar >.

virtual void vtkAbstractArray::InterpolateTuple	(	vtkIdType	i,
		vtkIdList *	ptIndices,
		vtkAbstractArray *	source,
		double *	weights
	)		`[pure virtual]`

Set the ith tuple in this array as the interpolated tuple value, given the ptIndices in the source array and associated interpolation weights. This method assumes that the two arrays are of the same type and strcuture.

Implemented in vtkVariantArray, vtkDataArray, vtkStringArray, vtkCPExodusIINodalCoordinatesTemplate< Scalar >, vtkCPExodusIIResultsArrayTemplate< Scalar >, vtkMappedDataArray< Scalar >, and vtkUnicodeStringArray.

		vtkAbstractArray *	source1,
		vtkIdType	id2,
		vtkAbstractArray *	source2,
		double	t
	)		`[pure virtual]`

Insert the ith tuple in this array as interpolated from the two values, p1 and p2, and an interpolation factor, t. The interpolation factor ranges from (0,1), with t=0 located at p1. This method assumes that the three arrays are of the same type. p1 is value at index id1 in source1, while, p2 is value at index id2 in source2.

Implemented in vtkVariantArray, vtkDataArray, vtkStringArray, vtkCPExodusIINodalCoordinatesTemplate< Scalar >, vtkCPExodusIIResultsArrayTemplate< Scalar >, vtkMappedDataArray< Scalar >, and vtkUnicodeStringArray.

virtual void vtkAbstractArray::SetVoidArray	(	void *	vtkNotUsedarray,
		vtkIdType	vtkNotUsedsize,
		int	vtkNotUsedsave
	)		`[pure virtual]`

This method lets the user specify data to be held by the array. The array argument is a pointer to the data. size is the size of the array supplied by the user. Set save to 1 to keep the class from deleting the array when it cleans up or reallocates memory. The class uses the actual array provided; it does not copy the data from the supplied array.

virtual void vtkAbstractArray::ExportToVoidPointer ( void * vtkNotUsedout_ptr ) [inline, virtual]

This method copies the array data to the void pointer specified by the user. It is up to the user to allocate enough memory for the void pointer.

Definition at line 249 of file vtkAbstractArray.h.

virtual unsigned long vtkAbstractArray::GetActualMemorySize ( ) [pure virtual]

Return the memory in kilobytes consumed by this data array. Used to support streaming and reading/writing data.

The information returned is valid only after the pipeline has been updated.

Implemented in vtkDataArray, vtkStringArray, vtkVariantArray, and vtkUnicodeStringArray.

virtual void vtkAbstractArray::SetName ( const char * ) [virtual]

Set/get array's name

virtual char* vtkAbstractArray::GetName ( ) [virtual]

Set/get array's name

virtual const char* vtkAbstractArray::GetDataTypeAsString ( void ) [inline, virtual]

Get the name of a data type as a string.

Definition at line 267 of file vtkAbstractArray.h.

Creates an array for dataType where dataType is one of VTK_BIT, VTK_CHAR, VTK_UNSIGNED_CHAR, VTK_SHORT, VTK_UNSIGNED_SHORT, VTK_INT, VTK_UNSIGNED_INT, VTK_LONG, VTK_UNSIGNED_LONG, VTK_DOUBLE, VTK_DOUBLE, VTK_ID_TYPE, VTK_STRING. Note that the data array returned has to be deleted by the user.

virtual int vtkAbstractArray::IsNumeric ( ) [pure virtual]

This method is here to make backward compatibility easier. It must return true if and only if an array contains numeric data.

Implemented in vtkVariantArray, vtkDataArray, vtkUnicodeStringArray, and vtkStringArray.

virtual vtkArrayIterator* vtkAbstractArray::NewIterator ( ) [pure virtual]

Subclasses must override this method and provide the right kind of templated vtkArrayIteratorTemplate.

Implemented in vtkDataArrayTemplate< T >, vtkStringArray, vtkBitArray, vtkVariantArray, vtkUnicodeStringArray, vtkCPExodusIINodalCoordinatesTemplate< Scalar >, and vtkCPExodusIIResultsArrayTemplate< Scalar >.

virtual vtkIdType vtkAbstractArray::GetDataSize ( ) [inline, virtual]

Returns the size of the data in DataTypeSize units. Thus, the number of bytes for the data can be computed by GetDataSize() * GetDataTypeSize(). Non-contiguous or variable- size arrays need to override this method.

Reimplemented in vtkStringArray.

Definition at line 291 of file vtkAbstractArray.h.

virtual vtkIdType vtkAbstractArray::LookupValue ( vtkVariant value ) [pure virtual]

virtual void vtkAbstractArray::InsertVariantValue	(	vtkIdType	idx,
		vtkVariant	value
	)		`[virtual]`

Insert a value into the array from a variant. This method does bounds checking.

virtual void vtkAbstractArray::SetVariantValue	(	vtkIdType	idx,
		vtkVariant	value
	)		`[pure virtual]`

Set a value in the array from a variant. This method does NOT do bounds checking.

Implemented in vtkDataArrayTemplate< T >, vtkVariantArray, vtkStringArray, vtkBitArray, vtkCPExodusIINodalCoordinatesTemplate< Scalar >, vtkCPExodusIIResultsArrayTemplate< Scalar >, vtkUnicodeStringArray, and vtkMappedDataArray< Scalar >.

virtual void vtkAbstractArray::DataChanged ( ) [pure virtual]

Tell the array explicitly that the data has changed. This is only necessary to call when you modify the array contents without using the array's API (i.e. you retrieve a pointer to the data and modify the array contents). You need to call this so that the fast lookup will know to rebuild itself. Otherwise, the lookup functions will give incorrect results.

Implemented in vtkDataArrayTemplate< T >, vtkStringArray, vtkVariantArray, vtkBitArray, vtkMappedDataArray< Scalar >, and vtkUnicodeStringArray.

virtual void vtkAbstractArray::ClearLookup ( ) [pure virtual]

Delete the associated fast lookup data structure on this array, if it exists. The lookup will be rebuilt on the next call to a lookup function.

virtual void vtkAbstractArray::GetProminentComponentValues	(	int	comp,
		vtkVariantArray *	values,
		double	uncertainty = `1.e-6`,
		double	minimumProminence = `1.e-3`
	)		`[virtual]`

Populate the given vtkVariantArray with a set of distinct values taken on by the requested component (or, when passed -1, by the tuples as a whole). If the set of prominent values has more than 32 entries, then the array is assumed to be continuous in nature and no values are returned. This method takes 2 parameters: uncertainty and minimumProminence. Note that this set of returned values may not be complete if uncertainty and minimumProminence are both larger than 0.0; in order to perform interactively, a subsample of the array is used to determine the set of values. The first parameter (uncertainty, U) is the maximum acceptable probability that a prominent value will not be detected. Setting this to 0 will cause every value in the array to be examined. The second parameter (minimumProminence, P) specifies the smallest relative frequency (in [0,1]) with which a value in the array may occur and still be considered prominent. Setting this to 0 will force every value in the array to be traversed. Using numbers close to 0 for this parameter quickly causes the number of samples required to obtain the given uncertainty to subsume the entire array, as rare occurrences require frequent sampling to detect. For an array with T tuples and given uncertainty U and mininumum prominence P, we sample N values, with N = f(T; P, U). We want f to be sublinear in T in order to interactively handle large arrays; in practice, we can make f independent of T: $N >= \frac{5}{P}\mathrm{ln}\left(\frac{1}{PU})$ , but note that small values of P are costly to achieve. The default parameters will locate prominent values that occur at least 1 out of every 1000 samples with a confidence of 0.999999 (= 1 - 1e6). Thanks to Seshadri Comandur (Sandia National Laboratories) for the bounds on the number of samples. The first time this is called, the array is examined and unique values are stored in the vtkInformation object associated with the array. The list of unique values will be updated on subsequent calls only if the array's MTime is newer than the associated vtkInformation object or if better sampling (lower uncertainty or minimumProminence) is requested. The DISCRETE_VALUE_SAMPLE_PARAMETERS() information key is used to store the numbers which produced any current set of prominent values. Also, note that every value encountered is reported and counts toward the maximum of 32 distinct values, regardless of the value's frequency. This is required for an efficient implementation. Use the vtkOrderStatistics filter if you wish to threshold the set of distinct values to eliminate "unprominent" (infrequently-occurring) values.

vtkInformation* vtkAbstractArray::GetInformation ( )

Get an information object that can be used to annotate the array. This will always return an instance of vtkInformation, if one is not currently associated with the array it will be created.

bool vtkAbstractArray::HasInformation ( ) [inline]

Inquire if this array has an instance of vtkInformation already associated with it.

virtual int vtkAbstractArray::CopyInformation	(	vtkInformation *	infoFrom,
		int	deep = `1`
	)		`[virtual]`

Copy information instance. Arrays use information objects in a variety of ways. It is important to have flexibility in this regard because certain keys should not be coppied, while others must be. NOTE: Subclasses must always call their superclass's CopyInformation method, so that all classes in the hierarchy get a chance to remove keys they do not wish to be coppied. The subclass will not need to explicilty copy the keys as it's handled here.

Reimplemented in vtkDataArray.

static vtkInformationIntegerKey* vtkAbstractArray::GUI_HIDE ( ) [static]

This key is a hint to end user interface that this array is internal and should not be shown to the end user.

static vtkInformationInformationVectorKey* vtkAbstractArray::PER_COMPONENT ( ) [static]

This key is used to hold a vector of COMPONENT_VALUES (and, for vtkDataArray subclasses, COMPONENT_RANGE) keys -- one for each component of the array. You may add additional per-component key-value pairs to information objects in this vector. However if you do so, you must be sure to either (1) set COMPONENT_VALUES to an invalid variant and set COMPONENT_RANGE to {VTK_DOUBLE_MAX, VTK_DOUBLE_MIN} or (2) call ComputeUniqueValues(component) and ComputeRange(component) before modifying the information object. Otherwise it is possible for modifications to the array to take place without the bounds on the component being updated since the modification time of the vtkInformation object is used to determine when the COMPONENT_RANGE values are out of date.

static vtkInformationVariantVectorKey* vtkAbstractArray::DISCRETE_VALUES ( ) [static]

A key used to hold discrete values taken on either by the tuples of the array (when present in this->GetInformation()) or individual components (when present in one entry of the PER_COMPONENT() information vector).

static vtkInformationDoubleVectorKey* vtkAbstractArray::DISCRETE_VALUE_SAMPLE_PARAMETERS ( ) [static]

A key used to hold conditions under which cached discrete values were generated; the value is a 2-vector of doubles. The first entry corresponds to the maximum uncertainty that prominent values exist but have not been detected. The second entry corresponds to the smallest relative frequency a value is allowed to have and still appear on the list.

virtual unsigned int vtkAbstractArray::GetMaxDiscreteValues ( ) [virtual]

Get/Set the maximum number of prominent values this array may contain before it is considered continuous. Default value is 32.

virtual void vtkAbstractArray::SetMaxDiscreteValues ( unsigned int ) [virtual]

Get/Set the maximum number of prominent values this array may contain before it is considered continuous. Default value is 32.

virtual int vtkAbstractArray::GetArrayType ( ) [inline, virtual]

Method for type-checking in FastDownCast implementations.

Reimplemented in vtkDataArray, vtkDataArrayTemplate< T >, vtkTypedDataArray< Scalar >, vtkTypedDataArray< T >, and vtkMappedDataArray< Scalar >.

virtual void vtkAbstractArray::SetInformation ( vtkInformation * ) [protected, virtual]

Set an information object that can be used to annotate the array. Use this with caution as array instances depend on persistence of information keys. See CopyInformation.

virtual void vtkAbstractArray::UpdateDiscreteValueSet	(	double	uncertainty,
		double	minProminence
	)		`[protected, virtual]`

Obtain the set of unique values taken on by each component of the array, as well as by the tuples of the array. The results are stored in the PER_COMPONENT() vtkInformation objects using the DISCRETE_VALUES() key. If the key is present but stores 0 values, the array either has no entries or does not behave as a discrete set. If the key is not present, the array has not been examined for distinct values or has been modified since the last examination.
