FTDictionaryServiceTransactionStepImpl

Abstract

A step using to update the dictionary of a particular graph

Methods

-performAction:: Called by the transaction controll in order to run the transaction
+transactionForOperationREMOVEOfNode: creates an transaction for removing a dictionary entry
+transactionForOperationREMOVEOfNode:withKey:withDictionaryServiceGraphImpl:transactionContext:: creates an transaction for removing a dictionary entry
+transactionForOperationSETOfNode: creates an transaction for adding/updating a dictionary entry
+transactionForOperationSETOfNode:withKey:withObject:withDictionaryServiceGraphImpl:transactionContext:: creates an transaction for adding/updating a dictionary entry
-undoAction:: removes all modifications previously been done by
