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 index in the list (only for indexed lists)

endIdx - The end index in the list (only for indexed lists)

Returns:

The List Iterator

Method to generate an SQLStatement for iterating through elements of the list. Selects the element 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:
