Interface IObsStorage

All Superinterfaces:

IBasicStorage

All Known Subinterfaces:

IObsStorageModule<ConfigType>

public interface IObsStorage
extends IBasicStorage

Adds support for storing/retrieving features of interests.
ObsKey and IObsFilter can be used in all record retrieval methods and concrete implementations must handle them properly (e.g. they must handle all obs filter criteria when they are specified)

Method Detail

getNumFois

int getNumFois(IFoiFilter filter)

Gets the number of features of interest matching the filter

Parameters:

filter - filtering criterias

Returns:

Number of features of interest registered in this storage

getFoisSpatialExtent

org.vast.util.Bbox getFoisSpatialExtent()

Gets the bounding rectangle of all features of interest contained in this storage

Returns:

bounding rectangle as Bbox instance

getFoiIDs

java.util.Iterator<java.lang.String> getFoiIDs(IFoiFilter filter)

Gets IDs of FOIs matching the filter

Parameters:

filter - filtering criterias

Returns:

A read-only iterator over IDs of features of interest

java.util.Iterator<net.opengis.gml.v32.AbstractFeature> getFois(IFoiFilter filter)

Retrieves features of interest matching the given filter

Parameters:

filter - filtering criterias

Returns:

A read-only iterator over matching FOIs

storeFoi

void storeFoi(java.lang.String producerID,
              net.opengis.gml.v32.AbstractFeature foi)
