    • getTypeInternal

      public static final Type.TypeHolder getTypeInternal(String signature) throws StringIndexOutOfBoundsException
      Convert signature to a Type object.
      Parameter:
      signature - signature string such as Ljava/lang/String;
      Gibt zurück:
      type object
      Löst aus:
      StringIndexOutOfBoundsException

    • getReturnType

      public static Type getReturnType(String signature)
      Convert return value of a method (signature) to a Type object.
      Parameter:
      signature - signature string such as (Ljava/lang/String;)V
      Gibt zurück:
      return type

    • getArgumentTypes

      public static Type[] getArgumentTypes(String signature)
      Convert arguments of a method (signature) to an array of Type objects.
      Parameter:
      signature - signature string such as (Ljava/lang/String;)V
      Gibt zurück:
      array of argument types

    • getArgumentSizes

      public static int getArgumentSizes(String signature)
      Work out the type of each argument in the signature and return the cumulative sizes of all the types (size means number of stack slots it consumes, eg double=2, int=1). Unlike the call above, this does minimal unpacking

    • getTypeSize

      public static int getTypeSize(String signature)
      Return the size of the type expressed in the signature. The signature should contain only one type.

    • getType

      public static Type getType(Class cl)
      Convert runtime java.lang.Class to BCEL Type object.
      Parameter:
      cl - Java class
      Gibt zurück:
      corresponding Type object

    • getSignature

      public static String getSignature(Method meth)

    • getSignature

      public static String getSignature(Constructor<?> cons)
