Member Function Documentation

GetPos()

virtual int PdsStream::GetPos ( ) const

pure virtual

Gets the current seek position in a stream. This is the position at which the next read or write will begin.

Returns

The current seek position.

GetRawDataSize()

virtual int PdsStream::GetRawDataSize ( ) const

pure virtual

Gets the stream raw data size.

Returns

The stream's dictionary

GetSize()

virtual int PdsStream::GetSize ( ) const

pure virtual

Gets the current size of a stream.

Returns

The size of the stream.

GetStreamDict()

virtual PdsDictionary * PdsStream::GetStreamDict ( )

pure virtual

Gets the stream dictionary object.

Returns

The stream's dictionary

IsEof()

virtual bool PdsStream::IsEof ( ) const

pure virtual

Checks if the current position is end of stream.

Returns

The size of the stream.

PsStream::Read

Read()

virtual bool PdsStream::Read ( int  offset, uint8_t *  buffer, int  size  ) const

pure virtual

Reads data from PsStream into memory.

Parameters

buffer	(Filled by the method) A buffer into which data is written.
offset	The position to start read from.
size	The number of bytes to read.

Returns

true if the operation was successful, false otherwise.
