public void insert(IQueryResult theQueryResult)
            throws QueryResultStoreException

Stores the given query result.

Specified by:

insert in interface IQueryResultStore

Parameters:

theQueryResult - The IQueryResult.

Throws:

copy

protected void copy(Record theSource,
                    Record theDestination)

copy all the attributes except: hibernateId and fields. TODO use reflection

copy

protected void copy(Field theSource,
                    Field theDestination)

Parameters:

theRecord - The record the field will be associated with.

theQueryParam - The provided IPointQueryParam.

Returns:

The created Field, or null if no mapping has been registered for the provided IQueryParam

createRecordFrom

protected Record createRecordFrom(IDataItem theDataItem)

Creates the corresponding Record for the provided IQuery.

Parameters:

theDataItem - The provided IQuery.

Returns:

The created Record.

getQueryParamHelper

protected IQueryParamHelper getQueryParamHelper(IQueryParam theQueryParam)

Retrieves the IQueryParamHelper corresponding to the provided query param.

Parameters:

theQueryParam - The provided query param.

Returns:

The corresponding IQueryParamHelper, or null if there is no corresponding IQueryParamHelper for the provided query param.
