Method Details

getMethodFromTypes

public static Method getMethodFromTypes(Class<?> agentClass,
 String methodName,
 Class<?>... parameterTypes)
                                 throws NoSuchMethodException

Returns the agent's method named methodName considering a given agentClass. This also works for private and inherited methods.

Parameters:

agentClass - the class wherein the search has to be started

methodName - the name of the method

parameterTypes - the parameter types of the targeted method

Returns:

the agent's method named methodName

Throws:

NoSuchMethodException - if the method cannot be found

getMethodOn

public static Method getMethodOn(Class<?> agentClass,
 String methodName,
 Object... argsSample)
                          throws NoSuchMethodException

Returns the agent's method named methodName considering a given agentClass and a sample of the arguments which could be passed to it. The purpose of this method is restricted to a limited number of use cases since getMethodFromTypes(Class, String, Class...) should be preferred if the exact signature of the searched method is known. A typical use case of this method is when the only information available is the arguments which are passed, for instance when overriding the Activator.execute(Object...) method and the like in Activator subclasses. This also works for private and inherited methods.

Parameters:

agentClass - the class wherein the search has to be made

methodName - the name of the method

argsSample - a sample of the args which can be passed to the method

Returns:

the agent's method named methodName

Throws:

NoSuchMethodException - if a matching method cannot be found
