Member Function Documentation

virtual const char* vtkZLibDataCompressor::GetClassName ( ) [virtual]

Reimplemented from vtkDataCompressor.

int vtkZLibDataCompressor::IsTypeOf ( const char * type ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkDataCompressor.

virtual int vtkZLibDataCompressor::IsA ( const char * type ) [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 vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkDataCompressor.

vtkZLibDataCompressor* vtkZLibDataCompressor::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkDataCompressor.

void vtkZLibDataCompressor::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 vtkDataCompressor.

vtkZLibDataCompressor* vtkZLibDataCompressor::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkObject.

unsigned long vtkZLibDataCompressor::GetMaximumCompressionSpace ( unsigned long size ) [virtual]

Get the maximum space that may be needed to store data of the given uncompressed size after compression. This is the minimum size of the output buffer that can be passed to the four-argument Compress method.
Implements vtkDataCompressor.

unsigned long vtkZLibDataCompressor::CompressBuffer ( const unsigned char * uncompressedData,

unsigned long uncompressedSize,

unsigned char * compressedData,

unsigned long compressionSpace

) [protected, virtual]

Implements vtkDataCompressor.

unsigned long vtkZLibDataCompressor::UncompressBuffer ( const unsigned char * compressedData,

unsigned long compressedSize,

unsigned char * uncompressedData,

unsigned long uncompressedSize

) [protected, virtual]

Implements vtkDataCompressor.
