Class WFSFeatureStore

Object
  AbstractFeatureSource
      WFSFeatureSource
          WFSFeatureStore

All Implemented Interfaces:

FeatureSource<SimpleFeatureType,SimpleFeature>, FeatureStore<SimpleFeatureType,SimpleFeature>, SimpleFeatureSource, SimpleFeatureStore

public class WFSFeatureStore
extends WFSFeatureSource
implements SimpleFeatureStore

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.
