Constructor Detail

StaticDependencyTraverser

public StaticDependencyTraverser(boolean traverse)

Creates a new traverser with the specified traversal behavior.

Parameters:

traverse - true to traverse all dependencies, false to never traverse.

Method Detail

traverseDependency

public boolean traverseDependency(Dependency dependency)

Description copied from interface: DependencyTraverser

Decides whether the dependencies of the specified dependency should be traversed.

Specified by:

traverseDependency in interface DependencyTraverser

Parameters:

dependency - The dependency to check, must not be null.

Returns:

true if the dependency graph builder should recurse into the specified dependency and process its dependencies, false otherwise.

deriveChildTraverser

public DependencyTraverser deriveChildTraverser(DependencyCollectionContext context)

Description copied from interface: DependencyTraverser

Derives a dependency traverser that will be used to decide whether the transitive dependencies of the dependency given in the collection context shall be traversed. When calculating the child traverser, implementors are strongly advised to simply return the current instance if nothing changed to help save memory.

Specified by:

deriveChildTraverser in interface DependencyTraverser

Parameters:

context - The dependency collection context, must not be null.

Returns:

The dependency traverser for the target node or null if dependencies should be unconditionally traversed in the sub graph.

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object
