    • Method Summary

      All Methods Static Methods Concrete Methods 
      Modifier and Type Method Description
      static java.lang.String getString​(org.apache.bcel.generic.Type type)
      Get String representation of a Type including Generic information
      static org.apache.bcel.generic.Type getType​(java.lang.String signature)
      This method is analogous to Type.getType(String), except that it also accepts signatures with generic information.
      static GenericObjectType getType​(java.lang.String className, java.util.List<? extends org.apache.bcel.generic.ReferenceType> parameters)  
      static GenericUtilities.TypeCategory getTypeCategory​(org.apache.bcel.generic.Type type)
      Get the TypeCategory that represents this Object
      static java.util.List<org.apache.bcel.generic.ReferenceType> getTypeParameters​(java.lang.String signature)
      Parse a bytecode signature that has 1 or more (possibly generic) types and return a list of the Types.
      static boolean isPlainObject​(org.apache.bcel.generic.Type type)  
      static int lastMatchedLeftAngleBracket​(java.lang.String s)  
      static org.apache.bcel.generic.ObjectType merge​(GenericObjectType t1, org.apache.bcel.generic.ObjectType t2)  
      static org.apache.bcel.generic.Type merge​(GenericObjectType t1, org.apache.bcel.generic.Type t2)  
      static org.apache.bcel.generic.ObjectType merge​(org.apache.bcel.generic.Type t1, org.apache.bcel.generic.ObjectType t2)  
      static int nextUnmatchedRightAngleBracket​(java.lang.String s, int startingAt)  
      static java.lang.String removeMatchedAngleBrackets​(java.lang.String s)  
      static java.util.List<java.lang.String> split​(java.lang.String signature, boolean skipInitialAngleBracket)

        Get String representation of a Type including Generic information

      • getType

        public static GenericObjectType getType​(java.lang.String className,
                                        java.util.List<? extends org.apache.bcel.generic.ReferenceType> parameters)

      • getType

        @CheckForNull
public static org.apache.bcel.generic.Type getType​(java.lang.String signature)
        This method is analogous to Type.getType(String), except that it also accepts signatures with generic information. e.g. Ljava/util/ArrayList<TT;>;

        The signature should only contain one type. Use GenericSignatureParser to break up a signature with many types or call createTypes(String) to return a list of types
