Method Detail

getTargetClass

public static java.lang.Class getTargetClass(java.lang.Object o)

Gets the "target" class of an object for looking up accessors that are registered on the target. If the object is a Class object this will return the Class itself, else it will return object's getClass() result.

Returns a unique descriptor string that includes the object's class' base name and a unique integer identifier.

toArray

public static java.lang.Object[] toArray(java.util.List list)

java.lang.IllegalAccessException

getArgClass

public static final java.lang.Class getArgClass(java.lang.Object arg)
