Class PreparedSQLStoreQuery.PreparedSQLExecutor

java.lang.Object
  org.apache.openjpa.kernel.AbstractStoreQuery.AbstractExecutor
      org.apache.openjpa.kernel.ExpressionStoreQuery.AbstractExpressionExecutor
          org.apache.openjpa.jdbc.kernel.PreparedSQLStoreQuery.PreparedSQLExecutor

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.

Class[]	getProjectionTypes(StoreQuery q)
QueryExpressions[]	getQueryExpressions()
Object[]	toParameterArray(StoreQuery q, Map userParams) Convert given userParams to an array whose ordering matches as per expected during executeXXX() methods.

Method Detail

getQueryExpressions

public QueryExpressions[] getQueryExpressions()

Specified by:

getQueryExpressions in interface StoreQuery.Executor

Overrides:

getQueryExpressions in class AbstractStoreQuery.AbstractExecutor

getProjectionTypes

public Class[] getProjectionTypes(StoreQuery q)

Specified by:

getProjectionTypes in interface StoreQuery.Executor

Overrides:

getProjectionTypes in class ExpressionStoreQuery.AbstractExpressionExecutor

executeQuery

public org.apache.openjpa.lib.rop.ResultObjectProvider executeQuery(StoreQuery q,
                                                                    Object[] params,
                                                                    StoreQuery.Range range)

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
