executeQuery

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

getDataStoreActions

public String[] getDataStoreActions(org.apache.openjpa.kernel.StoreQuery q,
                                    Object[] params,
                                    org.apache.openjpa.kernel.StoreQuery.Range range)

Specified by:

getDataStoreActions in interface org.apache.openjpa.kernel.StoreQuery.Executor

Overrides:

getDataStoreActions in class org.apache.openjpa.kernel.AbstractStoreQuery.AbstractExecutor

isPacking

public boolean isPacking(org.apache.openjpa.kernel.StoreQuery q)

Specified by:

isPacking in interface org.apache.openjpa.kernel.StoreQuery.Executor

Overrides:

isPacking in class org.apache.openjpa.kernel.AbstractStoreQuery.AbstractExecutor

toParameterArray

public Object[] toParameterArray(org.apache.openjpa.kernel.StoreQuery q,
                                 Map userParams)

The given query is parsed to find the parameter tokens of the form ?n which is different than ? tokens in actual SQL parameter tokens. These ?n style tokens are replaced in the query string by ? tokens. During the token parsing, the ordering of the tokens is recorded. The given userParam must contain parameter keys as Integer and the same Integers must appear in the tokens.
