Constructor & Destructor Documentation

CLAM::SegmentTransformation::SegmentTransformation ( )

Parameters:

c

SegmentTransformationConfig object created by the user

References CLAM_ASSERT.

bool CLAM::SegmentTransformation::ConcreteConfigure ( const ProcessingConfig & c ) [virtual]

Configuration change method.

Note that the Amount Control is initialized from the the values in the configuration. Appart from that the member boolean variable that indicates whether a BPF is used is also initialized and the On/Off control also.

Parameters:

The

ProcessingConfig object

Returns:: True if the cast has been commited correctly

Reimplemented from CLAM::Processing.

Reimplemented in CLAM::SegmentSMSMorph, and CLAM::SegmentSMSTimeStretch.

Definition at line 94 of file SegmentTransformation.cxx.

References CLAM::Processing::CopyAsConcreteConfig(), CLAM::InControlPublisher::DoControl(), mAmountCtrl, mConfig, and mUseTemporalBPF.

const ProcessingConfig& CLAM::SegmentTransformation::GetConfig ( ) const [inline, virtual]

Configuration getter.

Gets the configuration parameters used to create the object.

Returns:: Const reference to the configuration object. The usual way to perform a configuration change in the processing object is to take a copy of this reference, to change it and to send it with the Configure method. If not overriden, it returns a NullProcessingConfig.

Reimplemented from CLAM::Processing.

Reimplemented in CLAM::SegmentSMSMorph.

Definition at line 86 of file SegmentTransformation.hxx.

References mConfig.

virtual bool CLAM::SegmentTransformation::DoWithSegments ( void ) [inline, virtual]

bool CLAM::SegmentTransformation::Do	(	const Segment &	in,
		Segment &	out
	)			`[protected, virtual]`

Unsupervised Do function, receives a Segment as input and output.

This overload is the one called from the supervised Do(). Note that if BPF parameter is used, the Amount control is also updated.

Parameters:

	input	the Segment that is input to the transformation
	out	the Segment that is output from the transformation.

Returns:: Boolean value, whether the process has finished successfully or not.

Reimplemented in CLAM::SegmentSMSMorph, and CLAM::SegmentSMSTimeStretch.

Member Data Documentation

SegmentTransformationConfig CLAM::SegmentTransformation::mConfig [protected]

Internally stored configuration.

Reimplemented in CLAM::SegmentSMSMorph.

Definition at line 50 of file SegmentTransformation.hxx.

Referenced by ConcreteConfigure(), GetConfig(), and UpdateControlValueFromBPF().

bool CLAM::SegmentTransformation::mUseTemporalBPF [protected]

Boolean member that indicates whether BPF or single value is to be used.

This is not a control because it is not supposed to change un run-time. It is rather a configuration parameter that can be automatically extracted from mConfig but it is placed here to make it more explicit.
