Detailed Description

This class reads another reader and changes it's delay.

Definition at line 41 of file AUD_DelayReader.h.


Constructor & Destructor Documentation

AUD_DelayReader::AUD_DelayReader ( AUD_IReader reader,
float  delay 
)

Creates a new delay reader.

Parameters:
readerThe reader to read from.
delayThe delay in seconds.

Definition at line 36 of file AUD_DelayReader.cpp.


Member Function Documentation

int AUD_DelayReader::getLength ( ) const [virtual]

Returns an approximated length of the source in samples. For readers of the type buffer this has to return a correct value!

Returns:
The length as sample count. May be negative if unknown.
See also:
getType

Reimplemented from AUD_EffectReader.

Definition at line 58 of file AUD_DelayReader.cpp.

References AUD_IReader::getLength(), 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 of the stream type, especially after seeking, it must though for the buffer ones.
See also:
getType

Reimplemented from AUD_EffectReader.

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

Request to read the next length samples out of the source. The buffer for reading has to stay valid until the next call of this method or until the reader is deleted.

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]bufferThe pointer to the buffer with the samples.

Reimplemented from AUD_EffectReader.

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

Seeks to a specific position in the source. This function must work for buffer type readers.

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.
