to a method or constructor whose parameter type is the given class.
If object is null this will return true because null is compatible
with any type.
|
| setSecurityManager | | public static void setSecurityManager(SecurityManager value)(Code) | | Sets the SecurityManager that OGNL uses to determine permissions for
invoking methods.
Parameters:
value - SecurityManager to set |
| toArray | | public static Object[] toArray(List list)(Code) | | Utility to convert a List into an Object[] array. If the list is zero
elements this will return a constant array; toArray() on List always
returns a new object and this is wasteful for our purposes.
