Detailed Description

Wraps a binary output stream with a VTK interface.

vtkOutputStream provides a VTK-style interface wrapping around a standard output stream. The access methods are virtual so that subclasses can transparently provide encoding of the output. Data lengths for Write calls refer to the length of the data in memory. The actual length in the stream may differ for subclasses that implement an encoding scheme.

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 vtkObjectBase.

Reimplemented in vtkBase64OutputStream.

◆ PrintSelf()

void vtkOutputStream::PrintSelf ( ostream &  os,

)
overridevirtual

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 vtkObject.

◆ SetStream()

virtual void vtkOutputStream::SetStream ( ostream *  )
virtual

Get/Set the real output stream.

◆ GetStream()

virtual ostream* vtkOutputStream::GetStream ( )
virtual

◆ StartWriting()

virtual int vtkOutputStream::StartWriting ( )
virtual

Called after the stream position has been set by the caller, but before any Write calls.

The stream position should not be adjusted by the caller until after an EndWriting call.

Reimplemented in vtkBase64OutputStream.

◆ Write()

virtual int vtkOutputStream::Write ( void const *  data,
size_t  length 
)
virtual

Write output data of the given length.

Reimplemented in vtkBase64OutputStream.

◆ EndWriting()

virtual int vtkOutputStream::EndWriting ( )
virtual

Called after all desired calls to Write have been made.

After this call, the caller is free to change the position of the stream. Additional writes should not be done until after another call to StartWriting.

Reimplemented in vtkBase64OutputStream.

◆ WriteStream()

int vtkOutputStream::WriteStream ( const char *  data,
