All known Subclasses:   org.geotools.data.jdbc.JDBCState,
ContentState
public class ContentState (Code)
State for a content entry.

This class maintains a cache of certain aspects of a feature type which are subject to the state of a dataset modified in a transaction. Examples of such content:

  • Type FeatureType (per FeatureTypeFactory )
  • key: "bounds"; value: Envelope of dataset
  • key: "count"; value: Number of features in dataset
