Constructor Detail

RDBMSJoinListStore

public RDBMSJoinListStore(org.datanucleus.metadata.AbstractMemberMetaData mmd,
                          CollectionTable collTable,
                          org.datanucleus.ClassLoaderResolver clr)

Constructor for an RDBMS implementation of a join list store.

Parameters:

mmd - Metadata for the owning field/property

collTable - The Join table

clr - ClassLoader resolver

Method Detail

listIterator

protected java.util.ListIterator listIterator(org.datanucleus.StateManager ownerSM,
                                              int startIdx,
                                              int endIdx)

Accessor for an iterator through the list elements.

Specified by:

listIterator in class org.datanucleus.store.mapped.scostore.AbstractListStore

Parameters:

ownerSM - State Manager for the container.

startIdx - The start point in the list (only for indexed lists).

endIdx - End index in the list (only for indexed lists).

Returns:

The List Iterator

getSQLStatementForIterator

protected SQLStatement getSQLStatementForIterator(org.datanucleus.StateManager ownerSM,
                                                  int startIdx,
                                                  int endIdx,
                                                  org.datanucleus.store.mapped.StatementClassMapping resultMapping,

Method to generate an SQLStatement for iterating through elements of the set. Selects the join table. Populates the resultMapping and paramMapping argument objects.

Parameters:

ownerSM - StateManager for the owner object

startIdx - start index to be retrieved (inclusive). Only for indexed list

endIdx - end index to be retrieved (exclusive). Only for indexed list

resultMapping - Mapping for the candidate result columns

paramMapping - Mapping for the input parameters

Returns:

The SQLStatement
