Method Detail

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)

Overrides:

getGeoColumnsQuery in class SpatialDatabasesDSMetadata

getSridQuery

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

Overrides:

getSridQuery in class SpatialDatabasesDSMetadata

getGeometryAttributes

public List<GeometryColumn> getGeometryAttributes(String datasetName)

Description copied from class: SpatialDatabasesDSMetadata

Retrieves list of geometric tables from a custom DB Query: Should use OGC metadata geoemtry_columns or equivalent mechanism according to target DB.

Specified by:

getGeometryAttributes in interface DataStoreMetadata

Overrides:

getGeometryAttributes in class SpatialDatabasesDSMetadata

Parameters:

datasetName - name of a dataset

Returns:

list of GeometryColumn's referenced in this dataset

getAddGeometryColumnStatement

public String getAddGeometryColumnStatement(String schemaName,
                                            String tableName,
                                            String geometryColumn,
                                            int srid,
                                            String geometryType,
                                            int dim)

Description copied from class: SpatialDatabasesDSMetadata

Creates the query String to add a GeometryColumn.

Note 1 : In PostGIS 2.x, srid=-1 is automatically converted to srid=0 by AddGeometryColumn function.

Note 2 : To stay compatible with PostGIS 1.x, last argument of AddGeometryColumn is omitted. As a consequence, geometry type uses type modifier rather than constraints (new default behaviour in 2.x)

The geometry column name must have its final form. Attribute name normalization is the responsability of the calling method.

Overrides:

getAddGeometryColumnStatement in class SpatialDatabasesDSMetadata

Parameters:

schemaName - the name of the Schema

tableName - the name of the Table

geometryColumn - the name of the geometry column

srid - the SRID for the geometry column

geometryType - the (SQL) geometry type as a String

dim - the coordinate dimension (2 or 3)

Returns:

a SQL query string to add a geometry column to a table

getAddSpatialIndexStatement

public String getAddSpatialIndexStatement(String schemaName,
                                          String tableName,
                                          String geometryColumn)

Description copied from class: SpatialDatabasesDSMetadata

Create statement to add a spatial index on the specified geometry column. The geometry column name must have its final form. Attribute name normalization is the responsability of the calling method.

Overrides:

getAddSpatialIndexStatement in class SpatialDatabasesDSMetadata

Parameters:

schemaName - unquoted schema name or null if default schema is used

tableName - unquoted table name

geometryColumn - unquoted geometry column name

Returns:

a sql string to add a spatial index
