Detailed Description

Stream cursor for dynamic/online memory streams. Supports trimming data from the start of the stream to save memory.

Member Function Documentation

endOfStream()

virtual bool Skylicht::Audio::COnlineMemoryStreamCursor::endOfStream ( )

virtual

Check if the cursor is at the end of the stream.

Returns

True if at EOF

Implements Skylicht::Audio::IStreamCursor.

read()

virtual int Skylicht::Audio::COnlineMemoryStreamCursor::read ( unsigned char * buff, int len )

virtual

Read data from the stream.

Parameters

buff	Destination buffer
len	Number of bytes to read

Returns

Number of bytes actually read

Implements Skylicht::Audio::IStreamCursor.

readyReadData()

virtual bool Skylicht::Audio::COnlineMemoryStreamCursor::readyReadData ( int len )

virtual

Check if a certain amount of data is ready to be read.

Parameters

len	Number of bytes to check

Returns

True if data is available

Implements Skylicht::Audio::IStreamCursor.

seek()

virtual int Skylicht::Audio::COnlineMemoryStreamCursor::seek ( int pos, EOrigin origin )

virtual

Move the cursor position.

Parameters

pos	Offset in bytes
origin	Where to seek from

Returns

0 on success, or -1 on error

Implements Skylicht::Audio::IStreamCursor.

size()

virtual int Skylicht::Audio::COnlineMemoryStreamCursor::size ( )

virtual

Get total size of the stream.

Returns

Size in bytes

Implements Skylicht::Audio::IStreamCursor.

tell()

virtual int Skylicht::Audio::COnlineMemoryStreamCursor::tell ( )

virtual

Get current cursor position.

Returns

Current position in bytes

Implements Skylicht::Audio::IStreamCursor.

trim()

virtual void Skylicht::Audio::COnlineMemoryStreamCursor::trim ( )

virtual

Remove all data before the current cursor position from the stream.

Reimplemented from Skylicht::Audio::IStreamCursor.
