isEntryCriterionSatisfied

public boolean isEntryCriterionSatisfied()

Description copied from interface: CmmnActivityExecution

The flag entryCriterionSatisfied will only be set to true, when this CmmnActivityExecution stays in state CaseExecutionState.NEW.

For example:

There exists:

• a Stage,
• the Stage contains two tasks (A and B) and
• task B has an entry criterion which is satisfied, when task A performs the transition create

When the Stage instance becomes active, two child case executions will be created for task A and task B. Both tasks are in the state CaseExecutionState.NEW. Now task A performs the create transition and so that the given sentry is triggered, that this is satisfied. Afterwards the sentry will be reseted, that the sentry is not satisfied anymore.

But task B is still in the state CaseExecutionState.NEW and will not be notified, that its' entry criterion has been satisfied. That's why the the flag entryCriterionSatisfied will be set to true on the case execution of task B in such a situation. When task B performs the transition into the state CaseExecutionState.AVAILABLE it can perform the next transition because the entry criterion has been already satisfied.

createChildExecutions

public List<CmmnExecution> createChildExecutions(List<CmmnActivity> activities)

Description copied from interface: CmmnActivityExecution

Creates new child case executions for each given CmmnActivity.

This method can be called when this case execution (which represents a Stage) transitions to ACTIVE state. The passed collection of activities are the planned items that should be executed in this Stage. So that for each given CmmnActivity a new case execution will be instantiated. Furthermore for each created child execution there happens a transition to the initial state AVAILABLE.
