org.geotools.data.efeature.internal.EFeatureInfoCache

{@link EFeatureInfo} cache class.

Each {@link EFeatureInfo} instance is uniquely identified by a key.

The key is constructed from the structure information and has following format:

 eKey := <eNsURI>/<eFolder>/<eFeature> where {@link EFeatureInfo#eNsURI() <eNsURI>}        := is the {@link EPackage#getNsURI() EMF package namespace URI} {@link EFeatureInfo#eFolderName() <eFolder>}       := is the {@link EFeatureFolderInfo#eName() folder name}{@link EFeatureInfo#eName() <eFeature>}      := is the {@link EClass#getName() name} of the {@link EFeature} compatible {@link EClass implementation}

NOTE: {@link EFeatureInfo} instances are cached using hard references. Each {@link EFeatureInfo} instance is required to call {@link #detach(EFeatureInfo)} when the context is {@link EFeatureContextFactory#dispose(EFeatureContext) disposed} to allow the garbage collector to reclaim allocated memory.
