Method Details

add

public FeatureKey add(BigId parentID,
 V value)
               throws DataStoreException

Description copied from interface: IFeatureStoreBase

Add a new feature to the store, generating a new key for it, and also add it as a child of the specified parent

Specified by:

add in interface IFeatureStoreBase<V extends IFeature,VF extends IFeatureStoreBase.FeatureField,F extends FeatureFilterBase<? super V>>

Parameters:

parentID - Internal ID of parent feature

value - New feature object

Returns:

The newly allocated key (internal ID)

Throws:

DataStoreException - if a feature with the same UID and valid time already exists, or if the parent ID is unknown

getParent

public BigId getParent(BigId internalID)

Description copied from interface: IFeatureStoreBase

Get a feature's parent ID

Specified by:

getParent in interface IFeatureStoreBase<V extends IFeature,VF extends IFeatureStoreBase.FeatureField,F extends FeatureFilterBase<? super V>>

Parameters:

internalID - Internal ID of feature

Returns:

Internal ID of parent feature or null if no feature with the given ID was found or the feature has no parent

getFeaturesBbox

public Bbox getFeaturesBbox()

Specified by:

getFeaturesBbox in interface IFeatureStoreBase<V extends IFeature,VF extends IFeatureStoreBase.FeatureField,F extends FeatureFilterBase<? super V>>

Returns:

Overall bounding rectangle of all features contained in this data store
