Module JavaClass::Analyse::Dependencies
In: lib/javaclass/analyse/dependencies.rb

Analyser to get dependencies of a whole Classpath (to be mixed into Dsl::LoadingClasspath). For an example see how to list all imported types.

Public Instance methods

external_types(&filter)

Determine all foreign imported types from all classes in this classpath. An additional block is used as filter on class names.

[Source]

# File lib/javaclass/analyse/dependencies.rb, line 45
      def external_types(&filter)
        used_types(&filter) - types(&filter)
      end
types(&filter)

Return all types in this classpath. An additional block is used as filter on class names. Returns a list of JavaQualifiedName. Requires a method names in the base class.

# File lib/javaclass/analyse/dependencies.rb, line 17
      def types(&filter)
        names(&filter).collect { |c| c.to_classname }.sort
      end
used_types(&filter)

Determine all imported types from all classes in this classpath. An additional block is used as filter on class names.

# File lib/javaclass/analyse/dependencies.rb, line 39
      def used_types(&filter)
        used_types_map(&filter).keys.sort
      end
used_types_map(&filter)

Determine all imported types from all classes in this classpath together with count of imports. An additional block is used as filter on class names. Requires a method values in the base class.

      def used_types_map(&filter)
        type_map = Hash.new(0) # class_name (JavaQualifiedName) => cnt
        values(&filter).collect { |clazz| clazz.imported_3rd_party_types }.flatten.each do |type|

          # hash keys need to be frozen to keep state
          if !type_map.include?(type)
            type = type.freeze 
          end

          type_map[type] += 1
        end
        type_map
      end
