mil.nga.giat.geowave.vector.adapter.FeatureDataAdapter
This data adapter will handle all reading/writing concerns for storing and retrieving GeoTools SimpleFeature objects to and from a GeoWave persistent store in Accumulo. If the implementor needs to write rows with particular visibility, this can be done by providing a FieldVisibilityHandler to a constructor or a VisibilityManagement to a constructor. When using VisibilityManagement, the feature attribute to contain the visibility meta-data is, by default, called GEOWAVE_VISIBILITY. This can be overridden by setting the UserData property 'visibility' to Boolean.TRUE for the feature attribute that describes the attribute that contains the visibility meta-data. persistedType.getDescriptor("someAttributeName").getUserData().put( "visibility", Boolean.TRUE) The adapter will use the SimpleFeature's default geometry for spatial indexing. The adaptor will use the first temporal attribute (a Calendar or Date object) as the timestamp of a temporal index. If the feature type contains a UserData property 'time' for a specific time attribute with Boolean.TRUE, then the attribute is used as the timestamp of a temporal index. If the feature type contains UserData properties 'start' and 'end' for two different time attributes with value Boolean.TRUE, then the attributes are used for a range index. If the feature type contains a UserData property 'time' for *all* time attributes with Boolean.FALSE, then a temporal index is not used.
