  • Method Details

    • getTypeCategory

      public static final GenericUtilities.TypeCategory getTypeCategory(org.apache.bcel.generic.Type type)
      Get the TypeCategory that represents this Object
      See Also:

    • isPlainObject

      public static final boolean isPlainObject(org.apache.bcel.generic.Type type)

    • getString

      public static final String getString(org.apache.bcel.generic.Type type)
      Get String representation of a Type including Generic information

    • getType

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

    • getType

      @CheckForNull public static org.apache.bcel.generic.Type getType(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

    • getTypeParameters

      @CheckForNull public static final List<org.apache.bcel.generic.ReferenceType> getTypeParameters(String signature)
      Parse a bytecode signature that has 1 or more (possibly generic) types and return a list of the Types.
      Parameters:
      signature - bytecode signature e.g. e.g. Ljava/util/ArrayList<Ljava/lang/String;>;Ljava/util/ArrayList<TT;>;Ljava/util/ArrayList<*>;
