Member Function Documentation

virtual const char* vtkZLibDataCompressor::GetClassName ( )
virtual

Reimplemented from vtkDataCompressor.

static int vtkZLibDataCompressor::IsTypeOf ( const char *  type)
static
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
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
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 
)
protectedvirtual

Implements vtkDataCompressor.

unsigned long vtkZLibDataCompressor::UncompressBuffer ( const unsigned char *  compressedData,
unsigned long  compressedSize,
unsigned char *  uncompressedData,
unsigned long  uncompressedSize 
)
protectedvirtual

Implements vtkDataCompressor.
