Method Detail

getLenientConstructor

public static com.noleme.commons.container.Pair<Constructor<?>,Object[]> getLenientConstructor(Class<?> type,
                                                                                                     Class<?>[] parameterTypes,
                                                                                                     Object[] parameters)
                                                                                              throws NoSuchMethodException

Attempts to find a constructor for the provided class matching with the provided parameter types, if the search fails, it will attempt to make type conversions from String arguments.

Parameters:

type - the type of the class on which to perform the lookup

parameterTypes - the types of arguments expected for the constructor signature

parameters - the original expected arguments for the constructor

Returns:

a matching Constructor instance paired with a functional set of arguments (with possible type re-interpretations)

Throws:

NoSuchMethodException - thrown if no matching constructor could be found and/or type conversions failed

getLenientMethod

public static com.noleme.commons.container.Pair<Method,Object[]> getLenientMethod(Class<?> type,
                                                                                        String methodName,
                                                                                        Class<?>[] parameterTypes,
                                                                                        Object[] parameters)
                                                                                 throws NoSuchMethodException

Attempts to find a method for the provided class matching with the provided parameter types.

Parameters:

type - the type of the class on which to perform the lookup

methodName - the name of the method

parameterTypes - the types of the arguments expected for the method signature

parameters - the original expected arguments for the method

Returns:

a matching Method instance paired with a functional set of arguments (with possible type re-interpretations)

Throws:

NoSuchMethodException - thrown if no matching method could be found and/or type conversions failed
