Constructor & Destructor Documentation

◆ Constant()

ca.uqac.lif.cep.functions.Constant.Constant ( Object value )

Creates a new constant.

Parameters

value The value associated to this constant

Definition at line 53 of file Constant.java.

Member Function Documentation

◆ duplicate()

Constant ca.uqac.lif.cep.functions.Constant.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.
