Detailed Description

a vtkAbstractArray subclass for strings

Points and cells may sometimes have associated data that are stored as strings, e.g. labels for information visualization projects. This class provides a clean way to store and access those strings.

(

)

const

void vtkStringArray::PrintSelf ( ostream &  os, vtkIndent  indent  )

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkAbstractArray.

int vtkStringArray::GetDataType ( )

inlinevirtual

Get the data type.

Implements vtkAbstractArray.

Definition at line 56 of file vtkStringArray.h.

int vtkStringArray::IsNumeric ( )

inlinevirtual

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

Implements vtkAbstractArray.

Definition at line 60 of file vtkStringArray.h.

void vtkStringArray::Initialize ( )

virtual

Release storage and reset array to initial state.

Implements vtkAbstractArray.

int vtkStringArray::GetDataTypeSize ( )

virtual

Return the size of the data type. WARNING: This may not mean what you expect with strings. It will return sizeof(std::string) and not take into account the data included in any particular string.

Implements vtkAbstractArray.

void vtkStringArray::Squeeze ( )

inlinevirtual

Free any unnecessary memory. Resize object to just fit data requirement. Reclaims extra memory.

Implements vtkAbstractArray.

Definition at line 72 of file vtkStringArray.h.

int vtkStringArray::Resize ( vtkIdType  numTuples )

virtual

Resize the array while conserving the data.

Implements vtkAbstractArray.

virtual void vtkStringArray::SetTuple ( vtkIdType  i, vtkIdType  j, vtkAbstractArray *  source  )

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.

Implements vtkAbstractArray.

virtual void vtkStringArray::InsertTuple ( vtkIdType  i, vtkIdType  j, vtkAbstractArray *  source  )

virtual

Insert the jth tuple in the source array, at ith location in this array. Note that memory allocation is performed as necessary to hold the data.

Implements vtkAbstractArray.

virtual void vtkStringArray::InsertTuples ( vtkIdList *  dstIds, vtkIdList *  srcIds, vtkAbstractArray *  source  )

virtual

Copy the tuples indexed in srcIds from the source array to the tuple locations indexed by dstIds in this array. Note that memory allocation is performed as necessary to hold the data.

Implements vtkAbstractArray.

virtual void vtkStringArray::InsertTuples ( vtkIdType  dstStart, vtkIdType  n, vtkIdType  srcStart, vtkAbstractArray *  source  )

virtual

Copy n consecutive tuples starting at srcStart from the source array to this array, starting at the dstStart location. Note that memory allocation is performed as necessary to hold the data.

Implements vtkAbstractArray.

virtual vtkIdType vtkStringArray::InsertNextTuple ( vtkIdType  j, vtkAbstractArray *  source  )

virtual

Insert the jth tuple in the source array, at the end in this array. Note that memory allocation is performed as necessary to hold the data. Returns the location at which the data was inserted.

Implements vtkAbstractArray.

virtual void vtkStringArray::InterpolateTuple ( vtkIdType  i, vtkIdList *  ptIndices, vtkAbstractArray *  source, double *  weights  )

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.

Implements vtkAbstractArray.

virtual void vtkStringArray::InterpolateTuple ( vtkIdType  i, vtkIdType  id1, vtkAbstractArray *  source1, vtkIdType  id2, vtkAbstractArray *  source2, double  t  )

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.

Implements vtkAbstractArray.

virtual void vtkStringArray::GetTuples ( vtkIdList *  ptIds, vtkAbstractArray *  output  )

virtual

Given a list of indices, return an array of values. You must insure that the output array has been previously allocated with enough space to hold the data and that the types match sufficiently to allow conversion (if necessary).

Reimplemented from vtkAbstractArray.

virtual void vtkStringArray::GetTuples ( vtkIdType  p1, vtkIdType  p2, vtkAbstractArray *  output  )

virtual

Get the values for the range of indices specified (i.e., p1->p2 inclusive). You must insure that the output array has been previously allocated with enough space to hold the data and that the type of the output array is compatible with the type of this array.

Reimplemented from vtkAbstractArray.

(

vtkIdType

id

)

Get the data at a particular index.

void vtkStringArray::SetValue ( vtkIdType  id, vtkStdString  value  )

inline

Set the data at a particular index. Does not do range checking. Make sure you use the method SetNumberOfValues() before inserting data.

Definition at line 153 of file vtkStringArray.h.

void vtkStringArray::SetValue	(	vtkIdType	id,

Implements vtkAbstractArray.

Definition at line 174 of file vtkStringArray.h.

void vtkStringArray::InsertValue	(	vtkIdType	id,
		vtkStdString	f
	)

Insert data at a specified position in the array.

Implements vtkAbstractArray.

void vtkStringArray::InsertVariantValue ( vtkIdType  idx, vtkVariant  value  )

virtual

Safely set a value in the array form a variant. Safely insert a value into the array from a variant.

Implements vtkAbstractArray.

vtkIdType vtkStringArray::InsertNextValue

Definition at line 214 of file vtkStringArray.h.

void* vtkStringArray::GetVoidPointer ( vtkIdType  id )

inlinevirtual

Get the address of a particular data index. Performs no checks to verify that the memory has been allocated etc.

Implements vtkAbstractArray.

Definition at line 215 of file vtkStringArray.h.

void vtkStringArray::DeepCopy ( vtkAbstractArray *  aa )

virtual

Deep copy of another string array. Will complain and change nothing if the array passed in is not a vtkStringArray.

Reimplemented from vtkAbstractArray.

void vtkStringArray::SetArray	(	vtkStdString *	array,
		vtkIdType	size,
		int	save
	)

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. If save is 0, then this class is free to delete the array when it cleans up or reallocates. In that case, it is required that the array was allocated using the C++ new operator (and not malloc).

virtual void vtkStringArray::SetVoidArray ( void *  array, vtkIdType  size, int  save  )

inlinevirtual

unsigned long vtkStringArray::GetActualMemorySize ( )

virtual

Return the memory in kibibytes (1024 bytes) consumed by this data array. Used to support streaming and reading/writing data. The value returned is guaranteed to be greater than or equal to the memory required to actually represent the data represented by this object. The information returned is valid only after the pipeline has been updated. This function takes into account the size of the contents of the strings as well as the string containers themselves.

Implements vtkAbstractArray.

virtual vtkArrayIterator* vtkStringArray::NewIterator ( )

virtual

Returns a vtkArrayIteratorTemplate<vtkStdString>.

Implements vtkAbstractArray.

virtual vtkIdType vtkStringArray::GetDataSize ( )

virtual

Returns the size of the data in DataTypeSize units. Thus, the number of bytes for the data can be computed by GetDataSize() * GetDataTypeSize(). The size computation includes the string termination character for each string.

Reimplemented from vtkAbstractArray.

virtual vtkIdType vtkStringArray::LookupValue ( vtkVariant  value )

virtual

Return the indices where a specific value appears.

Implements vtkAbstractArray.

virtual void vtkStringArray::LookupValue ( vtkVariant  value, vtkIdList *  ids  )

virtual

Return the indices where a specific value appears.

Implements vtkAbstractArray.

vtkIdType vtkStringArray::LookupValue

(

vtkStdString

value

)

Return the indices where a specific value appears.

void vtkStringArray::LookupValue	(	vtkStdString	value,
		vtkIdList *	ids
	)

Return the indices where a specific value appears.

vtkIdType vtkStringArray::LookupValue

(

const char *

value

)

Return the indices where a specific value appears.

void vtkStringArray::LookupValue	(	const char *	value,
		vtkIdList *	ids
	)

Return the indices where a specific value appears.

virtual void vtkStringArray::DataChanged ( )

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.

Implements vtkAbstractArray.

virtual void vtkStringArray::DataElementChanged ( vtkIdType  id )

virtual

Tell the array explicitly that a single data element has changed. Like DataChanged(), then is only necessary when you modify the array contents without using the array's API.

virtual void vtkStringArray::ClearLookup ( )

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.

Implements vtkAbstractArray.
