parentNodes
The resultant tree parent nodes for the currently visited node. |
private DependencyNode |
rootNode
The root node of the resultant tree. |
private DependencyNodeVisitor |
visitor
The dependency node visitor to apply on the resultant dependency tree, or null for none. |
Constructor Summary | |

BuildingDependencyNodeVisitor()
Creates a dependency node visitor that clones visited nodes into a new dependency tree. |
|
BuildingDependencyNodeVisitor(DependencyNodeVisitor visitor)
Creates a dependency node visitor that clones visited nodes into a new dependency tree, and then applies the specified dependency node visitor on the resultant dependency tree. |
