Member Function Documentation

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

Reimplemented from vtkDataCompressor.

static int vtkZLibDataCompressor::IsTypeOf ( const char *  name  )  [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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkDataCompressor.

virtual int vtkZLibDataCompressor::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 vtkDataCompressor.

static 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.

static 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.

virtual void vtkZLibDataCompressor::SetCompressionLevel ( int   )  [virtual]

Get/Set the compression level.

virtual int vtkZLibDataCompressor::GetCompressionLevel (  )  [virtual]

Get/Set the compression level.

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.
