Constructor & Destructor Documentation

AUD_DoubleReader::AUD_DoubleReader	(	AUD_Reference< AUD_IReader >	reader1,
		AUD_Reference< AUD_IReader >	reader2
	)

Creates a new double reader.

Parameters:

reader1	The first reader to read from.
reader2	The second reader to read from.

Definition at line 34 of file AUD_DoubleReader.cpp.

AUD_DoubleReader::~AUD_DoubleReader

(

)

[virtual]

Destroys the reader.

Member Function Documentation

int AUD_DoubleReader::getLength

(

)

const [virtual]

Returns an approximated length of the source in samples.

Returns:

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

Implements AUD_IReader.

Definition at line 64 of file AUD_DoubleReader.cpp.

int AUD_DoubleReader::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.

Implements AUD_IReader.

Definition at line 73 of file AUD_DoubleReader.cpp.

AUD_Specs AUD_DoubleReader::getSpecs

(

)

const [virtual]

Returns the specification of the reader.

Returns:

The AUD_Specs structure.

Implements AUD_IReader.

Definition at line 78 of file AUD_DoubleReader.cpp.

bool AUD_DoubleReader::isSeekable

(

)

const [virtual]

Tells whether the source provides seeking functionality or not.

Warning:

This doesn't mean that the seeking always has to succeed.

Returns:

Always returns true for readers of buffering types.

Implements AUD_IReader.

Definition at line 47 of file AUD_DoubleReader.cpp.

void AUD_DoubleReader::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.

Implements AUD_IReader.

Definition at line 83 of file AUD_DoubleReader.cpp.

References AUD_COMPARE_SPECS, AUD_Specs::channels, len(), and length().

void AUD_DoubleReader::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.

Implements AUD_IReader.
