MethodUtils instances should NOT be constructed in standard programming. Instead, the class should be used as MethodUtils.getAccessibleMethod(method).

This constructor is public to permit tools that require a JavaBean instance to operate.

Method Detail

getAccessibleMethod

public static Method getAccessibleMethod(Method method)

Returns an accessible method (that is, one that can be invoked via reflection) that implements the specified Method. If no such method can be found, return null.

Parameters:

method - The method that we wish to call

Returns:

The accessible method

getMatchingAccessibleMethod

public static Method getMatchingAccessibleMethod(Class<?> cls,
                                                 String methodName,
                                                 Class<?>... parameterTypes)

Finds an accessible method that matches the given name and has compatible parameters. Compatible parameters mean that every method parameter is assignable from the given parameters. In other words, it finds a method with the given name that will take the parameters given.

This method can match primitive parameter by passing in wrapper classes. For example, a Boolean will match a primitive boolean parameter.

Parameters:

cls - find method in this class

methodName - find method with this name

parameterTypes - find method with most compatible parameters

Returns:

The accessible method
