Member Function Documentation

createReader()

virtual std::shared_ptr< IReader > Envelope::createReader ( )

virtual

Creates a reader for playback of the sound source.

Returns

A pointer to an IReader object or nullptr if there has been an error.

Exceptions

Exception

An exception may be thrown if there has been a more unexpected error during reader creation.

Implements ISound.
