Method Detail

visit

public boolean visit(WorkflowBean node)

Description copied from interface: Visitor

Called by WorkflowBean.accept(Visitor) when the visited bean is a leaf node.

A leaf node is a bean that can't have children, like InputWorkflowPort, PortNode or PropertyLiteral.

Specified by:

visit in interface Visitor

Parameters:

node - the currently visited WorkflowBean

Returns:

true if the visits over the current beans' siblings should continue, false to immediately leave the parent.

See Also:

Visitor.visitEnter(WorkflowBean)

visitEnter

public boolean visitEnter(WorkflowBean node)

Description copied from interface: Visitor

Called by WorkflowBean.accept(Visitor) when first visiting a bean which potentially has children.

After visiting the children (which could be none), WorkflowBean.accept(Visitor) on the current bean will call Visitor.visitLeave(WorkflowBean).

Note that a bean can have some children which are visited with Visitor.visit(WorkflowBean) and others which are visited with Visitor.visitEnter(WorkflowBean) (depending on if they themselves can have children).

Specified by:

visitEnter in interface Visitor

Parameters:

node - the currently visited WorkflowBean

Returns:

true if the children of this bean should be visited.

Visitor.visit(WorkflowBean), Visitor.visitLeave(WorkflowBean)

visitLeave

public boolean visitLeave(WorkflowBean node)

Description copied from interface: Visitor

Called by WorkflowBean.accept(Visitor) before leaving a bean previously visited with Visitor.visitEnter(WorkflowBean). This is called after all of the bean's children have been recursively visited, even if any of those aborted the visit by returning false.

Specified by:

visitLeave in interface Visitor

Parameters:

node - the currently visited WorkflowBean

Returns:

false if the visits over the current beans' siblings should continue, false to immediately leave the parent.
