getMethod

public static java.lang.reflect.Method getMethod(java.lang.Object target,
                                                 java.lang.String methodName,
                                                 java.lang.Class[] argTypes)
                                          throws java.lang.SecurityException,
                                                 java.lang.NoSuchMethodException

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:

java.lang.SecurityException - if security violation

java.lang.NoSuchMethodException - if no such method

getMethod

public static java.lang.reflect.Method getMethod(java.lang.Class target,
                                                 java.lang.String methodName,
                                                 java.lang.Class[] argTypes,
                                                 boolean isStaticReference)
                                          throws java.lang.SecurityException,
                                                 java.lang.NoSuchMethodException

java.lang.SecurityException

java.lang.NoSuchMethodException

getConstructor

public static java.lang.reflect.Constructor getConstructor(java.lang.Class targetClass,
                                                           java.lang.Class[] argTypes)
                                                    throws java.lang.SecurityException,
                                                           java.lang.NoSuchMethodException

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:

java.lang.NoSuchMethodException - if constructor not found.

java.lang.SecurityException
