redefineClasses
public static void redefineClasses(OpenJPAConfiguration conf,
Map<Class,byte[]> classes)
- For each element in
classes
, this method will redefine
all the element's methods such that field accesses are intercepted
in-line. If canRedefineClasses()
returns false
,
this method is a no-op.
canRedefineClasses
public static boolean canRedefineClasses()
- Returns:
- whether or not this VM has an instrumentation installed that
permits redefinition of classes. This assumes that all the arguments
will be modifiable classes according to
java.lang.instrument.Instrumentation#isModifiableClass
, and
only checks whether or not an instrumentation is available and
if retransformation is possible.
