                             boolean visitThenAcceptOrder)

Method Detail

isConcurrent

public boolean isConcurrent()

Specified by:

isConcurrent in interface ContextVisitor<T extends Context>

isCurrentThenChildrenOrder

public boolean isCurrentThenChildrenOrder()

Specified by:

isCurrentThenChildrenOrder in interface ContextVisitor<T extends Context>

Returns:

true if this visitor should traverse context in forward order, i.e. first visit the children list, then process the current node; otherwise visitor first processes the current node and then visits the children. The forward order is usually preferable but can be unsuitable for example when visitor structurally modifies the subtree during traversal.

shouldVisit

public boolean shouldVisit(T context)
                    throws ContextException

Specified by:

shouldVisit in interface ContextVisitor<T extends Context>

Throws:

ContextException

getTasks

public java.util.LinkedList<java.util.concurrent.Callable<java.lang.Object>> getTasks()

Specified by:

getTasks in interface ContextVisitor<T extends Context>

isStartContext

public boolean isStartContext()

Specified by:

isStartContext in interface ContextVisitor<T extends Context>
