Method Detail

getPrecedingDependencies

public java.util.List<Dependency> getPrecedingDependencies()

Description copied from interface: DependencyCycle

Gets the dependencies that lead to the first dependency on the cycle, starting from the root of the dependency graph.

Specified by:

getPrecedingDependencies in interface DependencyCycle

Returns:

The (read-only) sequence of dependencies that precedes the cycle in the graph, potentially empty but never null.

getCyclicDependencies

public java.util.List<Dependency> getCyclicDependencies()

Description copied from interface: DependencyCycle

Gets the dependencies that actually form the cycle. For example, a -> b -> c -> a, i.e. the last dependency in this sequence duplicates the first element and closes the cycle. Hence the length of the cycle is the size of the returned sequence minus 1.

Specified by:

getCyclicDependencies in interface DependencyCycle

Returns:

The (read-only) sequence of dependencies that forms the cycle, never null.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
