Member Function Documentation

bool CLAM::ADSR::ConcreteConfigure ( const ProcessingConfig )
virtual

Configuration method interface.

The Processing base class forces all the concrete classes derived from it to implement this method, which must actually perform the specific configuration tasks.

Note that the user can not call this method directly. He will use Configure instead. The argument is expected to be an object of the necesary concrete configuration class.

Parameters:
Referenceto the configuration object.
Returns:
false if the object is not yet fully configured. (For example, if some important configuration attribute such as number of ports was set to zero in the config object)

true if the processing object is left in a consistent state, and can be executed.

Exceptions:
Thismethod must throw a bad_cast exception if the argument is not an object of the expected configuration class.

bool CLAM::ADSR::Do ( void  )
virtual

Supervised mode execution method (using ports)

Returns:
A boolean telling whether it has been output

const char* CLAM::ADSR::GetClassName ( ) const
inlinevirtual

Override it in every subclass and retur the name of that class.

Implements CLAM::Processing.

Definition at line 109 of file ADSR.hxx.

const ProcessingConfig& CLAM::ADSR::GetConfig ( ) const
inlinevirtual

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.
