Detailed Description

template<class ScalarTypeT>
class vtkBuffer< ScalarTypeT >

internal storage class used by vtkSOADataArrayTemplate, vtkAOSDataArrayTemplate, and others.

vtkBuffer makes it easier to keep data pointers in vtkDataArray subclasses. This is an internal class and not intended for direct use expect when writing new types of vtkDataArray subclasses.

◆ SetBuffer()

template<class ScalarTypeT>
void vtkBuffer< ScalarT >::SetBuffer ( ScalarType array,
vtkIdType  size 
)

Set the memory buffer that this vtkBuffer object will manage.

array is a pointer to the buffer data and size is the size of the buffer (in number of elements).

Definition at line 106 of file vtkBuffer.h.

◆ SetFreeFunction()

template<typename ScalarT >
void vtkBuffer< ScalarT >::SetFreeFunction ( bool  noFreeFunction,
void(*)(void *)  deleteFunction = free 
)

Set the free function to be used when releasing this object.

If noFreeFunction is true, the buffer will not be freed when this vtkBuffer object is deleted or resize – otherwise, deleteFunction will be called to free the buffer

◆ Reallocate()

template<typename ScalarT >
bool vtkBuffer< ScalarT >::Reallocate ( vtkIdType  newsize)

Allocate a new buffer that holds newsize elements.

Old data is preserved.
