virtual void seek (int position)
virtual int getLength () const
virtual int getPosition () const
virtual void read (int &length, bool &eos, sample_t *buffer)

Detailed Description

This class reads another reader and loops it.

Note:
The other reader must be seekable.

Definition at line 40 of file AUD_LoopReader.h.


Constructor & Destructor Documentation

AUD_LoopReader::AUD_LoopReader ( AUD_Reference< AUD_IReader reader,
int  loop 
)

Creates a new loop reader.

Parameters:
readerThe reader to read from.
loopThe desired loop count, negative values result in endless looping.

Definition at line 35 of file AUD_LoopReader.cpp.


Member Function Documentation

int AUD_LoopReader::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 57 of file AUD_LoopReader.cpp.

References AUD_EffectReader::m_reader.

int AUD_LoopReader::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 64 of file AUD_LoopReader.cpp.

References AUD_EffectReader::m_reader.

void AUD_LoopReader::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]lengthThe 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]eosEnd of stream, whether the end is reached or not.
[in]bufferThe pointer to the buffer to read into.

Reimplemented from AUD_EffectReader.

Definition at line 69 of file AUD_LoopReader.cpp.

References AUD_Specs::channels, len(), length(), and AUD_EffectReader::m_reader.

void AUD_LoopReader::seek ( int  position) [virtual]

Seeks to a specific position in the source.

Parameters:
positionThe 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.
