Method Detail

visit

public boolean visit(DependencyNode node)

Starts the visit to the specified dependency node.

Specified by:

visit in interface DependencyNodeVisitor

Parameters:

node - the dependency node to visit

Returns:

true to visit the specified dependency node's children, false to skip the specified dependency node's children and proceed to its next sibling

endVisit

public boolean endVisit(DependencyNode node)

Ends the visit to to the specified dependency node.

Specified by:

endVisit in interface DependencyNodeVisitor

Parameters:

node - the dependency node to visit

Returns:

true to visit the specified dependency node's next sibling, false to skip the specified dependency node's next siblings and proceed to its parent

getDependencyNodeVisitor

public DependencyNodeVisitor getDependencyNodeVisitor()

Gets the dependency node visitor that this visitor applies on the resultant dependency tree.

Returns:

the dependency node visitor, or null for none

getDependencyTree

public DependencyNode getDependencyTree()

Gets the root node of the resultant dependency tree constructed by this visitor.

Returns:

the root node, or null if the source tree has not yet been visited
