Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`afterExternalization()`	Called by the virtualizer after the object's data is externalized, but before the virtual data is `removed`.
`void`	`afterInternalization()`	Called by the virtualizer after the object's data was made available to the object.
`void`	`beforeExternalization()`	Called by the virtualizer before the object's data is externalized.
`void`	`ensureVirtualData()`	Ensure that the virtual data is set to the object.
`JRVirtualizationContext`	`getContext()`	Returns the virtualization context this object belongs to.
`String`	`getUID()`	Used by the virtualizer to identify the data for this object.
`T`	`getVirtualData()`	Used by the virtualizer to get data.
`void`	`removeVirtualData()`	Used by the virtualizer to remove the data from the object in memory so that it may be garbage collected.
`void`	`setVirtualData(T o)`	Used by the virtualizer to set data.
