All Implemented Interfaces:
StoreQuery.Executor
Enclosing class:
PreparedSQLStoreQuery

public static class PreparedSQLStoreQuery.PreparedSQLExecutor
extends ExpressionStoreQuery.AbstractExpressionExecutor

Executor of a prepared query uses the QueryExpressions of the original query available via the PreparedQuery.

Constructor Detail

PreparedSQLStoreQuery.PreparedSQLExecutor

public PreparedSQLStoreQuery.PreparedSQLExecutor(PreparedSQLStoreQuery q,
                                                 ClassMetaData candidate)
Method Detail

getQueryExpressions

public QueryExpressions[] getQueryExpressions()
Description copied from interface: StoreQuery.Executor
Return the parsed query expressions for our candidate types. The expressions are available only after query has been parsed.

Specified by:
getQueryExpressions in interface StoreQuery.Executor
Overrides:
getQueryExpressions in class AbstractStoreQuery.AbstractExecutor

getProjectionTypes

public Class[] getProjectionTypes(StoreQuery q)
Description copied from interface: StoreQuery.Executor
Return the expected types of the projections used by this query, or an empty array if not a projection.

Specified by:
getProjectionTypes in interface StoreQuery.Executor
Overrides:
getProjectionTypes in class ExpressionStoreQuery.AbstractExpressionExecutor

executeQuery

public ResultObjectProvider executeQuery(StoreQuery q,
                                         Object[] params,
                                         StoreQuery.Range range)
Description copied from interface: StoreQuery.Executor
Return the result of executing this query with the given parameter values. If this query is a projection and this executor does not pack results itself, each element of the returned result object provider should be an object array containing the projection values.

StoreQuery.Executor.isPacking(org.apache.openjpa.kernel.StoreQuery)

toParameterArray

public Object[] toParameterArray(StoreQuery q,
                                 Map userParams)
Convert given userParams to an array whose ordering matches as per expected during executeXXX() methods. The given userParams is already re-parameterized, so this method have to merely copy the given Map values.

Specified by:
toParameterArray in interface StoreQuery.Executor
Overrides:
toParameterArray in class ExpressionStoreQuery.AbstractExpressionExecutor
Returns:
array with parameter values ordered in the same way as this receiver's executeXXX() method expects.
