Method Detail

• matchSingleParameterMethod

  public static com.google.common.base.Predicate<java.lang.reflect.Method> matchSingleParameterMethod(java.lang.String methodName,
                                                                                      java.lang.Object argument)

  Returns a predicate that matches a method with the given name, and a single parameter that TypeCoercions.tryCoerce(Object, com.google.common.reflect.TypeToken) can process from the given argument.

  Parameters:

  methodName - name of the method

  argument - argument that is intended to be given

  Returns:

  a predicate that will match a compatible method

• tryFindAndInvokeSingleParameterMethod

  public static Maybe<?> tryFindAndInvokeSingleParameterMethod(java.lang.Object instance,
                                               java.lang.String methodName,
                                               java.lang.Object argument)

  Tries to find a single-parameter method with a parameter compatible with (can be coerced to) the argument, and invokes it.

  Parameters:

  instance - the object to invoke the method on

  methodName - the name of the method to invoke

  argument - the argument to the method's parameter.

  Returns:

  the result of the method call, or Maybe.absent() if method could not be matched.

• matchMultiParameterMethod

  public static com.google.common.base.Predicate<java.lang.reflect.Method> matchMultiParameterMethod(java.lang.String methodName,
                                                                                     java.util.List<?> arguments)

  Returns a predicate that matches a method with the given name, and parameters that TypeCoercions.tryCoerce(Object, com.google.common.reflect.TypeToken) can process from the given list of arguments.

  Parameters:

  methodName - name of the method

  arguments - arguments that is intended to be given

  Returns:

  a predicate that will match a compatible method

• tryFindAndInvokeMultiParameterMethod

  public static Maybe<?> tryFindAndInvokeMultiParameterMethod(java.lang.Object instance,
                                              java.lang.String methodName,
                                              java.util.List<?> arguments)

  Tries to find a multiple-parameter method with each parameter compatible with (can be coerced to) the corresponding argument, and invokes it.

  Parameters:

  instance - the object to invoke the method on

  methodName - the name of the method to invoke

  argument - a list of the arguments to the method's parameters.

  Returns:

  the result of the method call, or Maybe.absent() if method could not be matched.

• tryFindAndInvokeBestMatchingMethod

  public static Maybe<?> tryFindAndInvokeBestMatchingMethod(java.lang.Object instance,
                                            java.lang.String methodName,
                                            java.lang.Object argument)

  Tries to find a method with each parameter compatible with (can be coerced to) the corresponding argument, and invokes it.

  Parameters:

  instance - the object to invoke the method on

  methodName - the name of the method to invoke

  argument - a list of the arguments to the method's parameters, or a single argument for a single-parameter method.

  Returns:

  the result of the method call, or Maybe.absent() if method could not be matched.
