• getMethodNamePrefix

  protected String getMethodNamePrefix()

• getMethod

  public Method getMethod(Class<?> clazz, String name, Class[] parameterTypes, boolean acceptPrivate, boolean acceptPackage, ComponentLogger logger) throws SuitableMethodNotAccessibleException, InvocationTargetException

  Finds the named public or protected method in the given class or any super class. If such a method is found, its accessibility is enfored by calling the Method.setAccessible method if required and the method is returned. Enforcing accessibility is required to support invocation of protected methods.

  Parameters:

  clazz - The Class which provides the method.

  name - The name of the method.

  parameterTypes - The parameters to the method. Passing null is equivalent to using an empty array.

  logger -

  Returns:

  The named method with enforced accessibility or null if no such method exists in the class.

  Throws:

  SuitableMethodNotAccessibleException - If method with the given name taking the parameters is found in the class but the method is not accessible.

  InvocationTargetException - If an unexpected Throwable is caught trying to access the desired method.

• accept

  protected static boolean accept(Method method, boolean acceptPrivate, boolean acceptPackage, boolean allowReturnValue)

  Returns true if the method is acceptable to be returned from the getMethod(Class, String, Class[], boolean, boolean, ComponentLogger) and also makes the method accessible.

  This method returns true iff:

  • The method has void return type
  • Is not static
  • Is public or protected
  • Is private and acceptPrivate is true
  • Is package private and acceptPackage is true

  This method is package private for unit testing purposes. It is not meant to be called from client code.

  Parameters:

  method - The method to check

  acceptPrivate - Whether a private method is acceptable

  acceptPackage - Whether a package private method is acceptable

  allowReturnValue - whether the method can return a value (to update service registration properties)

  Returns:

  whether the method is acceptable

• getPackageName

  public static String getPackageName(Class<?> clazz)

  Returns the name of the package to which the class belongs or an empty string if the class is in the default package.

• invoke

  public MethodResult invoke(Object componentInstance, P rawParameter, MethodResult methodCallFailureResult)

  Calls the declared method on the given component with the provided method call arguments.

  Parameters:

  componentInstance - The component instance on which to call the method

  rawParameter - The parameter container providing the actual parameters to provide to the called method

  methodCallFailureResult - The result to return from this method if calling the method resulted in an exception.

  logger -

  Returns:

  true if the method was called successfully or the method was not found and was not required. false if the method was not found but required. methodCallFailureResult is returned if the method was found and called, but the method threw an exception.

• methodExists

  public boolean methodExists(ComponentLogger logger)
