Method Detail

getSqlBuilder

public SpatialDatabasesSQLBuilder getSqlBuilder(SpatialReferenceSystemID srid,
                                                String[] colNames)

Keeps a reference on SpatialiteDSMetadata into the SQL builder, to access Spatialite preferences necessary in order to build proper queries according to geometric type

Specified by:

getSqlBuilder in interface DataStoreConnection

Overrides:

getSqlBuilder in class SpatialDatabasesDSConnection

Parameters:

srid - srid of the dataset

colNames - list of column names

Returns:

the SpatialDatabasesSQLBuilder

executeFilterQuery

Overrides:

executeAdhocQuery in class SpatialDatabasesDSConnection

Parameters:

query - the query to execute

Returns:

the results of the query

Throws:

SQLException - if an SQLException occurs

Exception - if no geometric column is found in the query

getValueConverterFactory

public SpatialiteValueConverterFactory getValueConverterFactory()

Overrides:

getValueConverterFactory in class SpatialDatabasesDSConnection
