This file is a collection of reflection utilities for dealing with
methods and constructors.
Author: Sanjiva Weerawarana Joseph Kesselman
Method Summary |
static Constructor | getConstructor(Class targetClass, Class[] argTypes) Class.getConstructor() finds only the entry point (if any)
_exactly_ matching the specified argument types. |
static Method | getMethod(Class target, String methodName, Class[] argTypes, boolean isStaticReference) |
static Method | getMethod(Object target, String methodName, Class[] argTypes)
Class.getMethod() finds only the entry point (if any) _exactly_
matching the specified argument types. |
public static Constructor getConstructor(Class targetClass, Class[] argTypes)
Class.getConstructor() finds only the entry point (if any)
_exactly_ matching the specified argument types. Our implmentation
can decide between several imperfect matches, using the same
search algorithm as the Java compiler.
Note that all constructors are static by definition, so
isStaticReference is true.
Throws: NoSuchMethodException if constructor not found.
public static Method getMethod(Class target, String methodName, Class[] argTypes, boolean isStaticReference)
public static Method getMethod(Object target, String methodName, Class[] argTypes)
Class.getMethod() finds only the entry point (if any) _exactly_
matching the specified argument types. Our implmentation can
decide between several imperfect matches, using the same search
algorithm as the Java compiler.
This version emulates the compiler behavior by allowing lookup to
be performed against either a class or an instance -- classname.foo()
must be a static method call, instance.foo() can invoke either static
or instance methods.
Parameters: target object on which call is to be made methodName name of method I'm lookin' for argTypes array of argument types of method
Returns: the desired method
Throws: SecurityException if security violation NoSuchMethodException if no such method
