Class Conditional

java.lang.Object

org.eclipse.viatra.integration.mwe2.mwe2impl.Conditional

All Implemented Interfaces:

ITransformationStep

public class Conditional
extends java.lang.Object
implements ITransformationStep

Composite transformation step that implements an IF style conditional construction. The condition is specified by an IConditionProvider which enables the specification of dynamically evaluated conditions. If the condition evaluation returns true, the ifTrue step is executed, if otherwise, the ifFalse step is executed. Note: As the condition is evaluated runtime, both of the steps is initialized.

initialize

public void initialize(org.eclipse.emf.mwe2.runtime.workflow.IWorkflowContext ctx)

Description copied from interface: ITransformationStep

In this method the transformation step can be initialized. The workflow context is handed to the transformation step

Specified by:

initialize in interface ITransformationStep

Parameters:

ctx - The context of the workflow, which can contain various workflow-specific resources.

execute

public void execute()

Description copied from interface: ITransformationStep

Defines the added functionality of the ITransformationStep object

Specified by:

execute in interface ITransformationStep

dispose

public void dispose()

Description copied from interface: ITransformationStep

If the transformation step contains any resources that need to be disposed of, it can be done here.

Specified by:

dispose in interface ITransformationStep
