                           org.datanucleus.ClassLoaderResolver clr)

Constructor for an RDBMS implementation of a join array store.

Parameters:

mmd - Metadata for the owning field/property

arrayTable - The Join table

clr - ClassLoader resolver

Method Detail

iterator

public java.util.Iterator iterator(org.datanucleus.StateManager ownerSM)

Method to return an iterator to the array.

Specified by:

iterator in interface org.datanucleus.store.scostore.ArrayStore

Specified by:

iterator in class org.datanucleus.store.mapped.scostore.AbstractArrayStore

Parameters:

ownerSM - StateManager for the owner of the array

getSQLStatementForIterator

protected SQLStatement getSQLStatementForIterator(org.datanucleus.StateManager ownerSM)

Method to generate an SQLStatement for iterating through elements of the set. Selects the join table. Populates the iteratorMappingDef and iteratorMappingParams.

Parameters:

ownerSM - StateManager for the owner object

Returns:

The SQLStatement
