Interface IIntegerArrayTransaction

All Superinterfaces:

IIntegerArray, ITransaction, IWritableIntegerArray

All Known Implementing Classes:

IntegerArrayTransaction

public interface IIntegerArrayTransaction
extends ITransaction, IWritableIntegerArray

A transaction on an IIntegerArray that contains the transient, writable state of the array.

The state is defined as the delta with respect to a base array.
The base array is never modified by those writes.
The writes are propagated to the base array only when and if the transaction is committed.

Method Details

getDelta

gnu.trove.map.TIntIntMap getDelta()

Returns the delta object containing the old values for this transaction.

The delta object is a mapping from a row ID to the old value for this row.

Returns:

the delta

getNewDelta

gnu.trove.map.TIntIntMap getNewDelta()

Returns the delta object containing the new values for this transaction.

The delta object is a mapping from a row ID to the new value for this row.

Returns:

the delta

reset

void reset()

Empties the array.

Its size will be set to 0.
