Method Detail

addSource

protected final void addSource(java.lang.StringBuilder sb)

Specified by:

addSource in class FilterReader<BDO extends DataObject,X>

getSourceTables

protected final java.util.Set<Repository> getSourceTables()

Specified by:

getSourceTables in class FilterReader<BDO extends DataObject,X>

getDBTag

protected final java.lang.String getDBTag()

Description copied from class: FilterReader

Get the tag used to create the connection for this query from a DatabaseService. Normally this just queries the repository for the main table in the query (as this table HAS to take part) and relies on the query failing if there is an illegal join. Any more advanced checking should really be done when constructing the filter as this is where there is a chance to recover from the error.

Specified by:

getDBTag in class FilterReader<BDO extends DataObject,X>
