Interface DependencyCycle

public interface DependencyCycle

A cycle within a dependency graph, that is a sequence of dependencies d_1, d_2, ..., d_n where d_1 and d_n have the same versionless coordinates. In more practical terms, a cycle occurs when a project directly or indirectly depends on its own output artifact.

This interface is not intended to be extended by clients.

Method Summary

Modifier and Type	Method	Description
java.util.List<Dependency>	getCyclicDependencies()	Gets the dependencies that actually form the cycle.
java.util.List<Dependency>	getPrecedingDependencies()	Gets the dependencies that lead to the first dependency on the cycle, starting from the root of the dependency graph.

Method Detail

getPrecedingDependencies

java.util.List<Dependency> getPrecedingDependencies()

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

Returns:

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

getCyclicDependencies

java.util.List<Dependency> getCyclicDependencies()

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.

Returns:

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