Field Detail

pack

java.lang.String pack

The package this class is in including the trailing dot or an empty string for the unnamed (aka default) package.

---

interfaces

java.lang.Class[] interfaces

The interfaces this class implements. Non-null, but possibly empty.

---

methods

Method[] methods

The Method objects this class must pass as the second argument to invoke (also useful for determining what methods this class has). Non-null, non-empty (includes at least Object.hashCode, Object.equals, and Object.toString).

---

exceptions

java.lang.Class[][] exceptions

The exceptions that do not need to be wrapped in UndeclaredThrowableException. exceptions[i] is the same as, or a subset of subclasses, of methods[i].getExceptionTypes(), depending on compatible throws clauses with multiple inheritance. It is unspecified if these lists include or exclude subclasses of Error and RuntimeException, but excluding them is harmless and generates a smaller class.

---

count

private static int count

For unique id's

---

id

final int id

The id of this proxy class

Constructor Detail

Proxy.ProxyData

Proxy.ProxyData()

Construct a ProxyData with uninitialized data members.

Method Detail

getPackage

private static java.lang.String getPackage(java.lang.Class k)

Return the name of a package (including the trailing dot) given the name of a class. Returns an empty string if no package. We use this in preference to using Class.getPackage() to avoid problems with ClassLoaders that don't set the package.

---

getProxyData

static Proxy.ProxyData getProxyData(Proxy.ProxyType pt)

Verifies that the arguments are legal, and sets up remaining data This should only be called when a class must be generated, as it is expensive.

---

isCoreObjectMethod

private static boolean isCoreObjectMethod(Method method)

Checks whether the method is similar to a public non-final method of Object or not (i.e. with the same name and parameter types). Note that we can't rely, directly or indirectly (via Collection.contains) on Method.equals as it would also check the declaring class, what we do not want. We only want to check that the given method have the same signature as a core method (same name and parameter types)
