Method Detail

getDefault

The default implementation always throws an IllegalArgumentException. If called by an overriding method, the last line of the overriding method should be return super.getDefault(type);. Provide a default instance of the given class.

Note calling this method twice for the same class should not be expected to return the same instance; however, there is no guarantee that the same instance will not be returned for two calls to this method.

Specified by:

getDefault in interface InstanceInitializer

Overrides:

getDefault in class AbstractInstanceInitializer

Type Parameters:

T - the class to get the default for

Parameters:

type - the class to get the default for

Returns:

the newly created default for the given class

getInitalizes

public java.util.Set<java.lang.Class<?>> getInitalizes()

The default implementation returns an empty set. Get the set of classes for which this InstanceInitializer can provide default instances for.

Specified by:

getInitalizes in interface InstanceInitializer

Overrides:

getInitalizes in class AbstractInstanceInitializer

Returns:

the set of classes this InstanceInitalizer supports; if empty, InstanceInitializer.getDefault(java.lang.Class) will never be called.
