Constructor Detail

AbstractMerit

protected AbstractMerit(Map<String,String> init)

Protected default constructor. Note that construction using an exisiting properties object is not supported. All information must be plunged into the property container either in the default subclasses constructor or later with the PropertyContainer.setProperty(java.lang.String, java.lang.String) method.

Method Detail

createMerit

public static Meriting createMerit(Map<String,String> prop)

Creates a meriting instance from a fully qualified class name. The class must support the default constructor.

initMerit

public void initMerit(Object obj)

Empty method for convenience. The very few classes that need initialization must override this method.

Specified by:

initMerit in interface Meriting

Parameters:

obj - An object used for initialization.

getInitializer

public Object getInitializer()

Returns null. If subclasses realy need an initializer, they should also override this method.

Specified by:

getInitializer in interface Meriting

Returns:

null if no initializer is needed.

writeObject

private void writeObject(ObjectOutputStream stream)
                  throws IOException

We customize object serialization. We serialize out properties.

Throws:

IOException

readObject

private void readObject(ObjectInputStream stream)
                 throws IOException,
                        ClassNotFoundException

On deserialization, first read the hidden object definitions, then the properties of this merit. The merit properties are then set using PropertyContainer.setProperties(java.util.Map<java.lang.String, java.lang.Object>).

Throws:

IOException

ClassNotFoundException
