Description copied from interface: TransactionContext

Adds a modification to the modification list.

Specified by:

addModification in interface TransactionContext

Parameters:

command - modification

getModifications

public List<WriteCommand> getModifications()

Description copied from interface: TransactionContext

Returns all modifications. If there are no modifications in this transaction this method will return an empty list.
