Public Class methods

new(pool, classidx)

Create a references container with the constant pool and skip references to index classidx which is the host class itself.

# File lib/javaclass/classfile/references.rb, line 12
      def initialize(pool, classidx)
        @constant_pool = pool
        @class_idx = classidx
      end

Public Instance methods

referenced_fields(includeown=false)

Return the constants referring to fields (Constants::ConstantField). If includeown is true then fields of this class are returned also.

# File lib/javaclass/classfile/references.rb, line 19
      def referenced_fields(includeown=false)
        @constant_pool.find(ConstantPool::FIELD_TAG).find_all do |field|
          includeown || field.class_index != @class_idx
        end
      end
referenced_methods(includeown=false)

Return the constants referring to methods (Constants::ConstantMethod) in classes or interfaces. If includeown is true then methods of this class are returned also.

# File lib/javaclass/classfile/references.rb, line 27
      def referenced_methods(includeown=false)
        @constant_pool.find(ConstantPool::METHOD_TAG, ConstantPool::INTERFACE_METHOD_TAG).find_all do |method|
          includeown || method.class_index != @class_idx
        end
      end
used_classes()

Return the list of all constant pool constantss containing class names of all used classes. Returns a list of ConstantClass.

# File lib/javaclass/classfile/references.rb, line 35
      def used_classes
        my_class_name = @constant_pool[@class_idx].class_name
        @constant_pool.find(ConstantPool::CLASS_TAG).find_all do |cl|
          cl.class_name != my_class_name 
        end
