FilteredProjectDependencyGraph

FilteredProjectDependencyGraph(ProjectDependencyGraph projectDependencyGraph,
                               java.util.Collection<? extends MavenProject> whiteList)

Creates a new project dependency graph from the specified graph.

Parameters:

projectDependencyGraph - The project dependency graph to create a sub view from, must not be null.

whiteList - The projects on which the dependency view should focus, must not be null.

Method Detail

getAllProjects

public java.util.List<MavenProject> getAllProjects()

Description copied from interface: ProjectDependencyGraph

Gets all collected projects.

Specified by:

getAllProjects in interface ProjectDependencyGraph

Returns:

All collected projects.

Since:

3.5.0

getSortedProjects

public java.util.List<MavenProject> getSortedProjects()

Description copied from interface: ProjectDependencyGraph

Gets all projects in their intended build order, i.e. after topologically sorting the projects according to their inter-dependencies.

Specified by:

getSortedProjects in interface ProjectDependencyGraph

Returns:

The projects in the build order, never null.

getDownstreamProjects

public java.util.List<MavenProject> getDownstreamProjects(MavenProject project,
                                                          boolean transitive)

Description copied from interface: ProjectDependencyGraph

Gets the downstream projects of the specified project. A downstream project is a project that directly or indirectly depends on the given project.

Specified by:

getDownstreamProjects in interface ProjectDependencyGraph

Parameters:

project - The project whose downstream projects should be retrieved, must not be null.

transitive - A flag whether to retrieve all direct and indirect downstream projects or just the immediate downstream projects.

Returns:

The downstream projects in the build order, never null.

getUpstreamProjects

public java.util.List<MavenProject> getUpstreamProjects(MavenProject project,
                                                        boolean transitive)

Description copied from interface: ProjectDependencyGraph

Gets the upstream projects of the specified project. An upstream project is a project that directly or indirectly is a prerequisite of the given project.

Specified by:

getUpstreamProjects in interface ProjectDependencyGraph

Parameters:

project - The project whose upstream projects should be retrieved, must not be null.

transitive - A flag whether to retrieve all direct and indirect upstream projects or just the immediate upstream projects.

Returns:

The upstream projects in the build order, never null.

applyFilter

private java.util.List<MavenProject> applyFilter(java.util.Collection<? extends MavenProject> projects)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
