entryAction

protected EccAction_FBcl entryAction

Often there is only one action (Operation + output event), then this aggregation is used. It is null if transitions is given, or if no action exists.

entryActions

protected java.util.List<EccAction_FBcl> entryActions

If more as one action is associated to the entry of the dstState, then this list is used and transition is null.

exitAction

EccAction_FBcl exitAction

Often there is only one exit action (Operation), then this aggregation is used. It is null if transitions is given, or if no action exists.

transition

transitions

Constructor Detail

EccState_FBcl

public EccState_FBcl(java.lang.String name)

Method Detail

addEntryAction

public void addEntryAction(EccAction_FBcl oper)

Adds an operation with an output event as entry.

Parameters:

oper -

addTransition

public void addTransition(EccTransition_FBcl transition)

removeTransitions

public void removeTransitions()

This state should be used in an EvinoutType_FBcl#actionState only to execute actions. This is possible only if the Ecc is simple regular, means it has only one active state, all other states are transient. This is one of the transient state. Remove its transition. No more necessary.

offerSrcEvent

public void offerSrcEvent(EvinoutType_FBcl evin,
                          Write_FBtype_FBwr fbtw)

Assign one event which enters this state with any transition. It sets oneTriggerEv if this is the only one, or bMoreEventSources. It sets also in all actions EccAction_FBcl#setTrgEvin(EvinoutType_FBcl, Write_FBtype_FBwr), see there. It does not set the action to the evin because it depends on the state whether the action is valid for the event. See Reader_FBcl#optimizeEcc there the action is set to the evin for simple regular state machines.

Parameters:

evin -

onlyOneTriggerEventSource

public EvinoutType_FBcl onlyOneTriggerEventSource()

iterEntryActions

public java.lang.Iterable<EccAction_FBcl> iterEntryActions()

nrofEntryActions

public int nrofEntryActions()

Returns the number of entry actions aggregated to this state.

Returns:

nrofTransitions

public int nrofTransitions()

Returns the number of entry actions aggregated to this state.

Returns:

iterTransitions

public java.lang.Iterable<EccTransition_FBcl> iterTransitions()

getOnlyOneTransition

public EccTransition_FBcl getOnlyOneTransition()

onlyOneEntryActions

public EccAction_FBcl onlyOneEntryActions()

returns the only one action if only one action is given, else null.

Returns:

null then use iterEntryActions() or check nrofEntryActions().

toString

public java.lang.String toString()

Overrides:
