Method Detail

getName

public String getName()
Return the name for this query result.


getDefiningType

public Class getDefiningType()
The class that defines this query result, or null if none.


setDefiningType

public void setDefiningType(Class cls)
The class that defines this query result, or null if none.


getColumnResults

public Object[] getColumnResults()

Return the mapped persistence-capable types in the query result.


addPCResult

public QueryResultMapping.PCResult addPCResult(Class candidate)
Add a mapped persistence-capable result with the given candidate type.


getSourceMode

public int getSourceMode()
