service LayerUpdateMerger
Description applies updates to a configuration layer. The configuration layer data is read from a XLayer and the changed layer is provided as XLayer again or described to a XLayerHandler .

Exported Interfaces
XUpdateHandler | Description accepts events describing the changes.
::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.
