static vtkVariantArray* vtkVariantArray::New ( )
static
static vtkTypeBool vtkVariantArray::IsTypeOf ( const char *  type)
static
virtual vtkTypeBool vtkVariantArray::IsA ( const char *  name)
virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkAbstractArray.

static vtkVariantArray* vtkVariantArray::SafeDownCast ( vtkObjectBase o)
static
virtual vtkObjectBase* vtkVariantArray::NewInstanceInternal ( ) const
protectedvirtual

Reimplemented from vtkAbstractArray.

vtkVariantArray* vtkVariantArray::NewInstance ( ) const
void vtkVariantArray::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
overridevirtual

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.

vtkTypeBool vtkVariantArray::Allocate ( vtkIdType  sz,
vtkIdType  ext = 1000 
)
overridevirtual

Allocate memory for this array.

Delete old storage only if necessary. Note that ext is no longer used.

Implements vtkAbstractArray.

void vtkVariantArray::Initialize ( )
overridevirtual

Release storage and reset array to initial state.

Implements vtkAbstractArray.

int vtkVariantArray::GetDataType ( )
overridevirtual

Return the underlying data type.

An integer indicating data type is returned as specified in vtkSetGet.h.

Implements vtkAbstractArray.

int vtkVariantArray::GetDataTypeSize ( )
overridevirtual

Return the size of the underlying data type.

For a bit, 1 is returned. For string 0 is returned. Arrays with variable length components return 0.

Implements vtkAbstractArray.

int vtkVariantArray::GetElementComponentSize ( )
overridevirtual

Return the size, in bytes, of the lowest-level element of an array.

For vtkDataArray and subclasses this is the size of the data type. For vtkStringArray, this is sizeof(vtkStdString::value_type), which winds up being sizeof(char).

Implements vtkAbstractArray.

void vtkVariantArray::SetNumberOfTuples ( vtkIdType  number)
overridevirtual

Set the number of tuples (a component group) in the array.

Note that this may allocate space depending on the number of components.

Implements vtkAbstractArray.

void vtkVariantArray::SetTuple ( vtkIdType  i,
vtkIdType  j,
vtkAbstractArray source 
)
overridevirtual

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.

void vtkVariantArray::InsertTuple ( vtkIdType  i,
vtkIdType  j,
vtkAbstractArray source 
)
overridevirtual

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.

void vtkVariantArray::InsertTuples ( vtkIdList dstIds,
vtkIdList srcIds,
vtkAbstractArray source 
)
overridevirtual

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.

void vtkVariantArray::InsertTuples ( vtkIdType  dstStart,
vtkIdType  n,
vtkIdType  srcStart,
vtkAbstractArray source 
)
overridevirtual

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.

vtkIdType vtkVariantArray::InsertNextTuple ( vtkIdType  j,
vtkAbstractArray source 
)
overridevirtual

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.

void* vtkVariantArray::GetVoidPointer ( vtkIdType  id)
overridevirtual

Return a void pointer.

For image pipeline interface and other special pointer manipulation.

Implements vtkAbstractArray.

void vtkVariantArray::DeepCopy ( vtkAbstractArray da)
overridevirtual

Deep copy of data.

Implementation left to subclasses, which should support as many type conversions as possible given the data type.

Reimplemented from vtkAbstractArray.

void vtkVariantArray::InterpolateTuple ( vtkIdType  i,
vtkIdList ptIndices,
vtkAbstractArray source,
double weights 
)
overridevirtual

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 structure.

Implements vtkAbstractArray.

void vtkVariantArray::InterpolateTuple ( vtkIdType  i,
vtkIdType  id1,
vtkAbstractArray source1,
vtkIdType  id2,
vtkAbstractArray source2,
double  t 
)
overridevirtual

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.

void vtkVariantArray::Squeeze ( )
overridevirtual

Free any unnecessary memory.

Description: Resize object to just fit data requirement. Reclaims extra memory.

Implements vtkAbstractArray.

vtkTypeBool vtkVariantArray::Resize ( vtkIdType  numTuples)
overridevirtual

Resize the array while conserving the data.

Returns 1 if resizing succeeded and 0 otherwise.

Implements vtkAbstractArray.

void vtkVariantArray::SetVoidArray ( void *  arr,
vtkIdType  size,
int  save 
)
override

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.

void vtkVariantArray::SetVoidArray ( void *  arr,
vtkIdType  size,
int  save,
int  deleteM 
)
override

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.

unsigned long vtkVariantArray::GetActualMemorySize ( )
overridevirtual

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.

Implements vtkAbstractArray.

int vtkVariantArray::IsNumeric ( )
overridevirtual

Since each item can be of a different type, we say that a variant array is not numeric.

Implements vtkAbstractArray.

vtkArrayIterator* vtkVariantArray::NewIterator ( )
overridevirtual

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

Implements vtkAbstractArray.

vtkVariant& vtkVariantArray::GetValue ( vtkIdType  id) const

Get the data at a particular index.

void vtkVariantArray::SetValue ( vtkIdType  id,
vtkVariant  value 
)

Set the data at a particular index.

Does not do range checking. Make sure you use the method SetNumberOfValues() before inserting data.

void vtkVariantArray::InsertValue ( vtkIdType  id,
vtkVariant  value

If id < GetNumberOfValues(), overwrite the array at that index.

If id >= GetNumberOfValues(), expand the array size to id+1 and set the final value to the specified value.

void vtkVariantArray::SetVariantValue ( vtkIdType  idx,
vtkVariant  value 
)
overridevirtual

Insert a value into the array from a variant.

Implements vtkAbstractArray.

Expand the array by one and set the value at that location.

Return the array index of the inserted value.

vtkVariant* vtkVariantArray::GetPointer ( vtkIdType  id)

Return a pointer to the location in the internal array at the specified index.

void vtkVariantArray::SetArray ( vtkVariant arr,
vtkIdType  size,
int  save,
int  deleteMethod = VTK_DATA_ARRAY_DELETE 
)

Set the internal array used by this object.

void vtkVariantArray::SetArrayFreeFunction ( void(*)(void *)  callback)
overridevirtual

This method allows the user to specify a custom free function to be called when the array is deallocated.

Calling this method will implicitly mean that the given free function will be called when the class cleans up or reallocates memory.

Implements vtkAbstractArray.

void vtkVariantArray::SetNumberOfValues ( vtkIdType  number)
overridevirtual

Specify the number of values for this object to hold.

Does an allocation as well as setting the MaxId ivar. Used in conjunction with SetValue() method for fast insertion.

Reimplemented from vtkAbstractArray.

vtkIdType vtkVariantArray::GetNumberOfValues ( )
inline

Return the number of values in the array.

vtkIdType vtkVariantArray::LookupValue ( vtkVariant  value)
overridevirtual

Return the indices where a specific value appears.

Implements vtkAbstractArray.

void vtkVariantArray::LookupValue ( vtkVariant  value,
vtkIdList ids 
)
overridevirtual

Return the indices where a specific value appears.

Implements vtkAbstractArray.

void vtkVariantArray::DataChanged ( )
overridevirtual

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 vtkVariantArray::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.

void vtkVariantArray::ClearLookup ( )
overridevirtual

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.
