Constructor Detail

Transition

public Transition()

Creates a new transition

Transition

public Transition(MooreMachine.Transition t)

Copies a transition from another transition

Parameters:

t - The transition to copy from

Method Detail

isFired

public boolean isFired(java.lang.Object[] inputs,
                       ca.uqac.lif.cep.Context context)

Determines if the transition fires for the given input

Parameters:

inputs - The input events

context - The context for the evaluation

Returns:

true if the transition fires, false otherwise

reset

public void reset()

Resets the state of the transition

modifyContext

public void modifyContext(java.lang.Object[] inputs,
                          java.lang.Object[] outputs,
                          MooreMachine machine)

Modifies the context of the state machine

Parameters:

inputs - The input parameters to the context assignment

outputs - The output parameters to the context assignment

machine - The Moore machine whose context is to be modified

getDestination

public int getDestination()

Gets the destination (i.e. target state) of that transition

Returns:

The destination state
