Examples of org.geotools.data.store.ContentFeatureSource

org.geotools.data.store.ContentFeatureSource
Abstract implementation of FeatureSource.
This feature source works off of operations provided by {@link FeatureCollection}. Individual SimpleFeatureCollection implementations are provided by subclasses:
Even though a feature source is read-only, this class is transaction aware. (see {@link #setTransaction(Transaction)}. The transaction is taken into account during operations such as {@link #getCount()} and {@link #getBounds()}since these values may be affected by another operation (like writing to a FeautreStore) working against the same transaction.

Subclasses must also implement the {@link #buildFeatureType()} method which builds the schema for the feature source.
