Member Function Documentation

int AUD_DelayReader::getLength

(

)

const [virtual]

Returns an approximated length of the source in samples.

Returns:

The length as sample count. May be negative if unknown.

Reimplemented from AUD_EffectReader.

Definition at line 55 of file AUD_DelayReader.cpp.

References len(), and AUD_EffectReader::m_reader.

int AUD_DelayReader::getPosition

(

)

const [virtual]

Returns the position of the source as a sample count value.

Returns:

The current position in the source. A negative value indicates that the position is unknown.

Warning:

The value returned doesn't always have to be correct for readers, especially after seeking.

Reimplemented from AUD_EffectReader.

Definition at line 63 of file AUD_DelayReader.cpp.

References AUD_EffectReader::m_reader.

void AUD_DelayReader::read	(	int &	length,
		bool &	eos,
		sample_t *	buffer
	)		[virtual]

Request to read the next length samples out of the source. The buffer supplied has the needed size.

Parameters:

[in,out]	length	The count of samples that should be read. Shall contain the real count of samples after reading, in case there were only fewer samples available. A smaller value also indicates the end of the reader.
[out]	eos	End of stream, whether the end is reached or not.
[in]	buffer	The pointer to the buffer to read into.

Reimplemented from AUD_EffectReader.

Definition at line 70 of file AUD_DelayReader.cpp.

void AUD_DelayReader::seek

(

int

position

)

[virtual]

Seeks to a specific position in the source.

Parameters:

position

The position to seek for measured in samples. To get from a given time to the samples you simply have to multiply the time value in seconds with the sample rate of the reader.

Warning:

This may work or not, depending on the actual reader.

Reimplemented from AUD_EffectReader.

Definition at line 41 of file AUD_DelayReader.cpp.
