Member Function Documentation

duplicate()

UnaryFunction<T, U> ca.uqac.lif.cep.functions.UnaryFunction< T, U >.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.
