public abstract class Utility
extends org.apache.bcel.classfile.Utility

Some Routines to convert from java.lang.Class to org.apache.bcel.generic.Type. These get round some inconsistencies with Class.getName() wrt primitives.

 e.g. 

  Character.Type.getName() returns char.

I think it should return C. Don't know if this is a code bug. But there's a bug on Bug Parade (#4369208) about the javadoc being misleading.

Method Detail

getType

public static org.apache.bcel.generic.Type getType(Class clazz)

Get the org.apache.bcel.generic.Type for a class. This handles the case where the class represents an n-dimensional array by relying on the fact that Class.getName() on an array returns the signature

 e.g.

   new Object[].getClass().getName() returns [Ljava.lang.Object;

Parameters:: clazz - a Class value
Returns:: a Type value
See Also:: Utility

getTypes

public static org.apache.bcel.generic.Type[] getTypes(Class[] classes)

Get the org.apache.bcel.generic.Type for an array of Classes

Parameters:: classes - a Class[] value
Returns:: a Type[] value

getObjectEquivalentClassName

public static String getObjectEquivalentClassName(org.apache.bcel.generic.BasicType t)

Get the Object equivalent Class name for a primitive

 e.g

   int   <-> java.lang.Integer
   char  <-> Character

Parameters:: t - a BasicType value
Returns:: a String value
Throws:: IllegalArgumentException - Unexpected type
