WFSFeatureStore
public class WFSFeatureStore
FeatureStore used to assemble a Transaction Request (issued during commit).
Please note this FeatureStore does not support working on Transaction.AUTO_COMMIT. Instead it builds up the Transaction request in a WFSTransactionState; each call to addFeatures, removeFeatures etc results in a series of "Actions" being recorded. These actions are used to both modify the contents you are looking at prior to commit being called; and to construct the Transaction Request when commit() is called.
