Constructor & Destructor Documentation

◆ IdentityFunction()

ca.uqac.lif.cep.functions.IdentityFunction.IdentityFunction ( int arity )

Creates a new identity function.

Parameters

arity The arity of the function

Member Function Documentation

◆ duplicate()

IdentityFunction ca.uqac.lif.cep.functions.IdentityFunction.duplicate ( boolean with_state )

Duplicates an object.

Optionally, set the object into the same state as the source object.

Parameters

with_state Set to true to replicate the object's state, false to create a new copy in the initial state.

Returns: Another object

Implements ca.uqac.lif.cep.Duplicable.
