Re: [Geotools-gt2-users] FeatureStore vs FeatureSource

[Chris H. <ch...@op...>]

A FeatureSource is a read only source of Features, mostly providing 
getFeatures().  A FeatureStore is used for transactions - it adds 
updateFeatures, addFeatures, deleteFeatures, as well as setting and 
getting Transactions.  So if you want to modify the source of your 
features you need to use a FeatureStore.  The idea is to have the 
capabilites be detectable from an instaceof, rather than using metadata.
