Method Detail

activate

public void activate(ActivationPurpose purpose)

Description copied from interface: Activatable

should be called by every reading field access of an object.

The recommended implementation of this method is to call Activator.activate(ActivationPurpose) on the Activator that was previously passed to Activatable.bind(Activator).

Specified by:

activate in interface Activatable

Parameters:

purpose - TODO

bind

public void bind(Activator activator)

Description copied from interface: Activatable

called by db4o upon instantiation.

The recommended implementation of this method is to store the passed Activator in a transient field of the object.

Specified by:

bind in interface Activatable

Parameters:

activator - the Activator
