Member Function Documentation

virtual void alize::FeatureFileReaderSingle::close ( ) [virtual]

Closes the opened file

Implements alize::FeatureInputStream.

bool alize::FeatureFileReaderSingle::featureWantedIsInHistoric ( ) const [private]

bool alize::FeatureFileReaderSingle::getBigEndian	(	const Config &	,
		BigEndian
	)		const `[protected]`

String alize::FeatureFileReaderSingle::getExt	(	const FileName &	,
		const Config &
	)		const `[protected]`

virtual unsigned long alize::FeatureFileReaderSingle::getFeatureCountOfASource ( unsigned long srcIdx ) [virtual]

Returns the feature count of a feature source (a file)

Parameters:

srcIdx index of the source

Returns:: the feature count of the source

Implements alize::FeatureInputStream.

virtual unsigned long alize::FeatureFileReaderSingle::getFeatureCountOfASource ( const String & srcName ) [virtual]

Returns the feature count of a feature source (a file)

Parameters:

srcName name of the source

Returns:: the feature count of the source

Implements alize::FeatureInputStream.

virtual unsigned long alize::FeatureFileReaderSingle::getFirstFeatureIndexOfASource ( const String & srcName ) [virtual]

Returns the number of the first feature of a feature source. Useful for a multiple source stream.

Parameters:

srcName name of the source

Returns:: the number of the first feature

Implements alize::FeatureInputStream.

virtual unsigned long alize::FeatureFileReaderSingle::getFirstFeatureIndexOfASource ( unsigned long srcIdx ) [virtual]

Returns the number of the first feature of a feature source. Useful for a multiple source stream.

Parameters:

srcIdx index of the source

Returns:: the number of the first feature

Implements alize::FeatureInputStream.

virtual unsigned long alize::FeatureFileReaderSingle::getHeaderLength ( ) [private, virtual]

Reimplemented in alize::FeatureFileReaderHTK, alize::FeatureFileReaderSPro3, and alize::FeatureFileReaderSPro4.

virtual const String& alize::FeatureFileReaderSingle::getNameOfASource ( unsigned long srcIdx ) [virtual]

Returns the a particular feature source. Useful for a multiple source stream.

Parameters:

srcIdx index of the source

Returns:: the name of the source

Implements alize::FeatureInputStream.

String alize::FeatureFileReaderSingle::getPath	(	const FileName &	,
		const Config &
	)		const `[protected]`

virtual unsigned long alize::FeatureFileReaderSingle::getSourceCount ( ) [virtual]

Returns the number of sources (files) read by the reader

Returns:: the number of sources

Implements alize::FeatureInputStream.

virtual bool alize::FeatureFileReaderSingle::readFeature	(	Feature &	f,
		unsigned long	s = `1`
	)		`[virtual]`

Reads a feature in the stream and move the pointer s step forward

Parameters:

f	the feature to store the data read
s	step (default value = 1)

Returns:: false if there is no more data because the end of the file has been reached

Exceptions:

IOException if an I/O error occurs

Implements alize::FeatureInputStream.

virtual void alize::FeatureFileReaderSingle::setExternalBufferToUse ( FloatVector & v ) [virtual]

Connects an external buffer to the reader. This buffer will replace the internal buffer.

Parameters:

v	the vector

Reimplemented from alize::FeatureFileReaderAbstract.

virtual String alize::FeatureFileReaderSingle::toString ( ) const [virtual]

This method is frequently overridden in the derived classes. If it is not, it returns the name of the class of the object and the address of the object
