Module JavaClass::Analyse::TransitiveDependencies
In: lib/javaclass/analyse/transitive_dependencies.rb

Transitive dependency analysis to be mixed into Dsl::LoadingClasspath. For an example see how to get cumulative dependencies of a class. For plain dependencies of a Classpath see Dependencies.

Public Instance methods

transitive_dependencies_package(package, &filter)

Creates the tree of all transitive dependencies of the Java package where every dependency is only listed once at its first occurence. It returns an AdderTree containing all found dependencies. An additional block is used as filter on class names to work with, e.g. the main classes. Requires a method names in the base class.

transitive_dependency_tree(classname, tree=nil, &filter)

Creates the tree of all transitive dependencies of classname where every dependency is only listed once at its first occurence. It returns an AdderTree containing all found dependencies. An additional block is used as filter on class names to work with, e.g. the main classes. Requires methods includes? and load in the base class.
