parametersSuitableForMethod

public static boolean parametersSuitableForMethod(Method m,
 Object[] params)

Check if a provided list of parameters can be used for a given method.

Parameters:

m - The method that should be inspected

params - The parameters that should be inspected

Returns:

True if the provided parameters can be used for the provided method

findSuitableMethods

public static List<Method> findSuitableMethods(Class<?> clazz,
 Object[] params,
 String methodName)

Find all methods in a class that match a given list of parameters. The parameters have to be provided in the order as they are passes to the method.

Parameters:
