Detailed Description

Wraps a binary input stream with a VTK interface.

vtkInputStream provides a VTK-style interface wrapping around a standard input stream. The access methods are virtual so that subclasses can transparently provide decoding of an encoded stream. Data lengths for Seek and Read calls refer to the length of the input data. The actual length in the stream may differ for subclasses that implement an encoding scheme.

◆ IsA()

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 vtkBase64InputStream.

◆ PrintSelf()

void vtkInputStream::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
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 vtkInputStream::SetStream ( istream *  )
virtual

Get/Set the real input stream.

◆ GetStream()

virtual istream* vtkInputStream::GetStream ( )
virtual

◆ StartReading()

virtual void vtkInputStream::StartReading ( )
virtual

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

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

Reimplemented in vtkBase64InputStream.

◆ Seek()

virtual int vtkInputStream::Seek ( vtkTypeInt64  offset)
virtual

Seek to the given offset in the input data.

Returns 1 for success, 0 for failure.

Reimplemented in vtkBase64InputStream.

◆ Read()

virtual size_t vtkInputStream::Read ( void *  data,
size_t  length 
)
virtual

Read input data of the given length.

Returns amount actually read.

Reimplemented in vtkBase64InputStream.

◆ EndReading()

virtual void vtkInputStream::EndReading ( )
virtual

Called after all desired calls to Seek and Read have been made.

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

Reimplemented in vtkBase64InputStream.

◆ ReadStream()
