Class ReflectionBase

java.lang.Object
  org.jikesrvm.runtime.ReflectionBase

public abstract class ReflectionBase
extends Object
extends Object

Base class for all reflective method invoker classes, contains utility methods that are invoked to unwrap the reflective arguments. Also contains invoke(RVMMethod, Object, Object[]) that is called to perform the reflective method call.

Field Summary
`static ReflectionBase`	`nullInvoker` Reflective method invoker that performs no invocation

Constructor Summary
`ReflectionBase()`

Method Summary
`protected static Object`	`boxAsBoolean(boolean b)` Wrap result as boolean
`protected static Object`	`boxAsByte(byte b)` Wrap result as byte
`protected static Object`	`boxAsChar(char c)` Wrap result as char
`protected static Object`	`boxAsDouble(double d)` Wrap result as double
`protected static Object`	`boxAsFloat(float f)` Wrap result as float
`protected static Object`	`boxAsInt(int i)` Wrap result as int
`protected static Object`	`boxAsLong(long l)` Wrap result as long
`protected static Object`	`boxAsShort(short s)` Wrap result as short
`Object`	`invoke(RVMMethod method, Object obj, Object[] args)` Invoke reflective method being wrapped by this object
`abstract Object`	`invokeInternal(Object obj, Object[] args)` Invoke reflective method being wrapped by this object, internal method specific part.
`private static void`	`throwIllegalArgumentException()` Throw error with argument
`protected static boolean`	`unboxAsBoolean(Object obj)` Unwrap boolean for call
`protected static byte`	`unboxAsByte(Object obj)` Unwrap boolean for call
