void closeFile

(

)

[private]

Function: closeFile()

Description: Close the file if its open, release memory, and release mad structs.

Definition at line 285 of file OggFileSource.cpp.

void getHeader

(

std::string

filename

)

[virtual]

Function: getHeader Description: Opens the Ogg file and collects all the necessary information to update the MarSystem.

Implements AbsSoundFileSource.

void myProcess	(	realvec &	in,
		realvec &	out
	)			[virtual]

Function: process Description: Fills an output vector with samples. In this case, getLinear16 does all the work.

Implements AbsSoundFileSource.

void myUpdate

(

MarControlPtr

sender

)

[private, virtual]

Function: update

Description: Performs the usual MarSystem update jobs. Additionally, it can update the position of the index in the file if the user seeks forward or backward. Note that this is currently going to be slow as we have to refill the mad buffer each time somebody seeks in the file.

Reimplemented from MarSystem.
