Examples of org.geotools.data.memory.MemoryDataStore

org.geotools.data.memory.MemoryDataStore
This is an example implementation of a DataStore used for testing.
It serves as an example implementation of:
- FeatureListenerManager use: allows handling of FeatureEvents
This class will also illustrate the use of In-Process locking when the time comes.
