# Interface DefaultParametersHandler<T>

Type Parameters:
  `T` - the type of parameters supported by this handler

All Known Implementing Classes:
  `CopyObjectDefaultHandler`

public interface DefaultParametersHandler<T>

Definition of an interface for setting default values for specific configuration parameter objects.

An object implementing this interface knows how to initialize a parameters object of a specific class with default values. Such objects can be registered at the `Parameters` class. Whenever a specific parameters object is created all registered `DefaultParametersHandler` objects that can handle this parameters type are invoked, so that they get the chance to perform arbitrary initialization.

  Modifier and Type
  Method
  Description
  `void`
  `initializeDefaults(T parameters)`
  Initializes the specified parameters object with default values.

- ## Method Details

  - ### initializeDefaults

    void initializeDefaults(T parameters)
    Initializes the specified parameters object with default values. This method is called after the parameters object was created and before it is passed to the calling code. A concrete implementation can perform arbitrary initializations. Note that if there are multiple `DefaultParametersHandler` objects registered supporting this parameters type they are called in the order they have been registered. So handlers registered later can override initializations done by handlers registered earlier.
    Parameters:
      `parameters` - the parameters object to be initialized
