The source and destination repositories are selected by arguments passed to ::com::sun::star::task::XJob::execute(). The names and meanings of such arguments depend on the implementation. Each implementation must document such arguments.

Implementations may return a value from ::com::sun::star::task::XJob::execute() that indicates the status of job execution. The type and meaning of such status indicators depend on the implementation.

If void or true is returned, this indicates successful execution. If an ::com::sun::star::uno::Exception is returned, it represents an error condition encountered during execution.

The following arguments to ::com::sun::star::task::XJob::execute() should be supported by implementations. Implementations must document a failure to support any of these arguments:

ImporterService : string

A service or implementation name used to instantiate the Importer to use for importing. If this parameter is missing, the implementation selects an appropriate importer. By default, a MergeImporter should be used.

OverwriteExisting : boolean

If true, specifies that no existing data should be overwritten by the import. If the Importer used does not support such protection, an error may be raised. If some data is not imported, because there is existing data, this is indicated by returning an appropriate exception.

TruncateExisting : boolean

If true, specifies that existing data should be discarded and replaced by the imported data. If the Importer used does not support this operation, an error may be raised. By default, a CopyImporter is used to perform truncating import.

Entity : string

An identifier for the entity in the destination backend for which the imported data should apply. The value will be passed to XLayerImporter::importLayerForEntity(). If this parameter is missing, the implementation uses XLayerImporter::importLayer() instead.

Component : string

Names the component for which to import data. If this parameter is missing, the selection of data to import depends on implementation-specific parameters.

LayerFilter : LayerFilter

A filter to transform data during import. This parameter is optional. If this parameter is missing, data will be imported unaltered. Support for this parameter is optional. If the implementation does not support a filter it will raise an ::com::sun::star::lang::IllegalArgumentException.
