Member Function Documentation
| 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 | ( | vtkObjectBase * | o | ) | [static] |
Reimplemented from vtkDataCompressor.
| virtual vtkObjectBase* vtkZLibDataCompressor::NewInstanceInternal | ( | ) | const [protected, virtual] |
Reimplemented from vtkDataCompressor.
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.
| size_t vtkZLibDataCompressor::GetMaximumCompressionSpace | ( | size_t | 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.
| size_t vtkZLibDataCompressor::CompressBuffer | ( | unsigned char const * | uncompressedData, |
| size_t | uncompressedSize, | ||
| unsigned char * | compressedData, | ||
| size_t | compressionSpace | ||
| ) | [protected, virtual] |
Implements vtkDataCompressor.
| size_t vtkZLibDataCompressor::UncompressBuffer | ( | unsigned char const * | compressedData, |
| size_t | compressedSize, | ||
| unsigned char * | uncompressedData, | ||
| size_t | uncompressedSize | ||
| ) | [protected, virtual] |
Implements vtkDataCompressor.
