SpatialiteDSMetadata

public SpatialiteDSMetadata(DataStoreConnection con)

Parameters:

con - a DataStoreConnection

Method Detail

getGeometryAttributes

protected List<GeometryColumn> getGeometryAttributes(String sql,
                                                     String datasetName)

Overridden to deal with indexed geometry columns, as queries to get features are different if spatial index is detected on the column. Builds a GeometryColumn object with 5 params constructor.

Overrides:

getGeometryAttributes in class SpatialDatabasesDSMetadata

Parameters:

sql - SQL string to retrieve geometry columns

datasetName - name of the dataset

Returns:

a List of GeometryColumn

getSpatialExtentQuery1

public String getSpatialExtentQuery1(String schema,
                                     String table,
                                     String attributeName)

Overrides:

getSpatialExtentQuery1 in class SpatialDatabasesDSMetadata

getSpatialExtentQuery2

public String getSpatialExtentQuery2(String schema,
                                     String table,
                                     String attributeName)

Overrides:

getSpatialExtentQuery2 in class SpatialDatabasesDSMetadata

getGeoColumnsQuery

public String getGeoColumnsQuery(String datasetName)

No schema in SQLite

Overrides:

getGeoColumnsQuery in class SpatialDatabasesDSMetadata

Parameters:

datasetName - name of the Dataset

Returns:

the SQL string to retrieve the geometry columns

getSridQuery

public String getSridQuery(String schemaName,
                           String tableName,
                           String colName)

Overrides:

getSridQuery in class SpatialDatabasesDSMetadata

isSpatialiteLoaded

public boolean isSpatialiteLoaded()

getSpatialiteVersion

public String getSpatialiteVersion()

setSpatialiteVersion

public void setSpatialiteVersion(String spatialiteVersion)

getGeometryColumnsLayout

public GeometryColumnsLayout getGeometryColumnsLayout()

getGeoColTypesdMap

public Map<String,GeometricColumnType> getGeoColTypesdMap()

setIndexInfo

protected void setIndexInfo(String datasetName,
                            GeometryColumn gc)

set if given gc column is spatially indexed (true/false) according to spatialite DB type

Parameters:

datasetName - the name of the dataset this column belongs to

gc - the geometry column to set

getGeometryColumn

public GeometryColumn getGeometryColumn(String datasetName,
                                        String geoCol)

Convenience method to get a geometryColumn object from this metadata

Parameters:

datasetName - the name of the dataset

geoCol - the name of the geo column

Returns:

a GeometryColumn object
