AndDependencyTraverser

public AndDependencyTraverser(DependencyTraverser... traversers)

Creates a new traverser from the specified traversers. Prefer newInstance(DependencyTraverser, DependencyTraverser) if any of the input traversers might be null.

Parameters:

traversers - The traversers to combine, may be null but must not contain null elements.

AndDependencyTraverser

public AndDependencyTraverser(Collection<? extends DependencyTraverser> traversers)

Creates a new traverser from the specified traversers.

Parameters:

traversers - The traversers to combine, may be null but must not contain null elements.

Method Detail

                                              DependencyTraverser traverser2)

Creates a new traverser from the specified traversers.

Parameters:

traverser1 - The first traverser to combine, may be null.

traverser2 - The second traverser to combine, may be null.

Returns:

The combined traverser or null if both traversers were null.
