Method Detail

classForName

Class classForName(String name,
                   String[] imports)

Resolve the type represented by the given class name. This will test the type against the namespace of the Query and the declared imports, and will properly handle primitives and java.lang types as well. Returns null if the name does not match a known type.

getFilterListener

FilterListener getFilterListener(String tag)

Return the filter listener for the given tag, or null if none.

getAggregateListener

AggregateListener getAggregateListener(String tag)

Return the function listener for the given tag, or null if none.

getConfiguration

OpenJPAConfiguration getConfiguration()

Return the OpenJPA configuration.

getQueryContext

QueryContext getQueryContext()

The QueryContext for which this resolver was created
