::com::sun::star::lang::XInitialization
Description
allows initializing layer data source and target.

Both source and target of the update can be provided by passing a XUpdatableLayer object. Alternatively they can be provided individually by providing a XLayer object as data source and an XLayerHandler object to receive the updated data.

Implementations can provide more arguments to finetune the behavior. Such arguments are provided as ::com::sun::star::beans::NamedValue . Implementations should support the following named arguments:

Overwrite : boolean
If false , specifies that changes should be applied only if the existing layer is empty.
Truncate : boolean
If true requests that changes should not be merged onto existing data, but that the changes should be applied to a layer that is completely empty.
