| Method Summary | |
| public SQLFunctionCall | buildSRSTransformCall(MappedGeometryPropertyType geoProperty, String targetSRS)
Returns an
SQLFunctionCall that refers to the given
MappingGeometryField in the specified target
SRS using a database specific SQL function. | | public String | buildSRSTransformCall(String geomIdentifier, int nativeSRSCode)
| | protected boolean | canTransformTo(String targetSRS)
Returns whether the datastore is capable of performing a native coordinate transformation (using an SQL function
call for example) into the given SRS. | | public Geometry | convertDBToDeegreeGeometry(Object value, CoordinateSystem targetCS, Connection conn)
Converts an Oracle specific geometry Object from the ResultSet to a deegree
Geometry. | | public STRUCT | convertDeegreeToDBGeometry(Geometry geometry, int nativeSRSCode, Connection conn)
Converts a deegree Geometry to an Oracle specific geometry object. | | public Object | convertFromDBType(Object rsObject, int sqlTypeCode)
Converts the given object from a java.sql.ResultSet column to the common type to be used as a
feature property. | | public static String | fromOracleSRIDCode(int srid)
| | public int | getNativeSRSCode(String srsName)
| | public static int | getOracleSRIDCode(String code)
| | public Object | getSequenceNextVal(Connection conn, String sequence)
Returns the next value of the given SQL sequence. | | public WhereBuilder | getWhereBuilder(MappedFeatureType[] rootFts, String[] aliases, Filter filter, SortProperty[] sortProperties, TableAliasGenerator aliasGenerator, VirtualContentProvider vcProvider)
Returns a specific
WhereBuilder implementation for Oracle Spatial. | | public PreparedStatement | prepareStatement(Connection conn, StatementBuffer statementBuffer)
Converts the
StatementBuffer into a
PreparedStatement , which is initialized and ready to be
performed. | | protected Query | transformQuery(Query query)
Transforms the incoming
Query so that the
CoordinateSystem of all spatial arguments (BBOX, etc.)
in the
Filter match the SRS of the targeted
MappingGeometryField s.
NOTE: If this transformation can be performed by the backend (e.g. | | protected FeatureCollection | transformResult(FeatureCollection fc, String targetSRS)
Transforms the
FeatureCollection so that the geometries of all contained geometry properties use the
requested SRS. |
| canTransformTo | | protected boolean canTransformTo(String targetSRS)(Code) | | Returns whether the datastore is capable of performing a native coordinate transformation (using an SQL function
call for example) into the given SRS.
Parameters:
targetSRS - target spatial reference system (usually "EPSG:XYZ") true, if the datastore can perform the coordinate transformation, false otherwise |
| convertDBToDeegreeGeometry | | public Geometry convertDBToDeegreeGeometry(Object value, CoordinateSystem targetCS, Connection conn) throws SQLException(Code) | | Converts an Oracle specific geometry Object from the ResultSet to a deegree
Geometry.
Parameters:
value -
Parameters:
targetCS -
Parameters:
conn - corresponding deegree geometry
throws:
SQLException - |
| convertDeegreeToDBGeometry | | public STRUCT convertDeegreeToDBGeometry(Geometry geometry, int nativeSRSCode, Connection conn) throws DatastoreException(Code) | | Converts a deegree Geometry to an Oracle specific geometry object.
Parameters:
geometry -
Parameters:
nativeSRSCode -
Parameters:
conn - corresponding Oracle specific geometry object
throws:
DatastoreException - |
| convertFromDBType | | public Object convertFromDBType(Object rsObject, int sqlTypeCode) throws DatastoreException(Code) | | Converts the given object from a java.sql.ResultSet column to the common type to be used as a
feature property.
NOTE: String- and boolean-valued results have a special conversion handling:
Strings: because we encountered difficulties when inserting empty strings "" into String-type
columns with NOT NULL constraints (for example in VARCHAR2 fields), "$EMPTY_STRING$" is used to mark them.Boolean:because Oracle has no special boolean type, it is assumed that a CHAR(1) column is used
instead (with values 'Y'=true and 'N'=false)
Parameters:
rsObject -
Parameters:
sqlTypeCode - an object that is suitable for a table column of the specified SQL type
throws:
DatastoreException - |
| fromOracleSRIDCode | | public static String fromOracleSRIDCode(int srid)(Code) | |
Parameters:
srid - an EPSG code or "-1", if none was found |
| getNativeSRSCode | | public int getNativeSRSCode(String srsName)(Code) | | |
| getOracleSRIDCode | | public static int getOracleSRIDCode(String code)(Code) | |
Parameters:
code - an EPSG code the oracle code as stored in srs_codes_oracle.properties |
| getSequenceNextVal | | public Object getSequenceNextVal(Connection conn, String sequence) throws DatastoreException(Code) | | Returns the next value of the given SQL sequence.
Parameters:
conn - JDBC connection to be used.
Parameters:
sequence - name of the SQL sequence next value of the given SQL sequence
throws:
DatastoreException - if the value could not be retrieved |
| getWhereBuilder | | public WhereBuilder getWhereBuilder(MappedFeatureType[] rootFts, String[] aliases, Filter filter, SortProperty[] sortProperties, TableAliasGenerator aliasGenerator, VirtualContentProvider vcProvider) throws DatastoreException(Code) | | Returns a specific
WhereBuilder implementation for Oracle Spatial.
Parameters:
rootFts - involved (requested) feature types
Parameters:
aliases - aliases for the feature types, may be null
Parameters:
filter - filter that restricts the matched features
Parameters:
sortProperties - sort criteria for the result, may be null or empty
Parameters:
aliasGenerator - used to generate unique table aliases
Parameters:
vcProvider - WhereBuilder implementation for Oracle Spatial
throws:
DatastoreException - |
| prepareStatement | | public PreparedStatement prepareStatement(Connection conn, StatementBuffer statementBuffer) throws SQLException(Code) | | Converts the
StatementBuffer into a
PreparedStatement , which is initialized and ready to be
performed.
TODO remove this method (use super class method instead), change handling of JGeometry NOTE: String- and
boolean-valued results have a special conversion handling:
Strings: because we encountered difficulties when inserting empty strings "" into String-type
columns with NOT NULL constraints (for example in VARCHAR2 fields), "$EMPTY_STRING$" is used to mark them.Boolean:because Oracle has no special boolean type, it is assumed that a CHAR(1) column is used
instead (with values 'Y'=true and 'N'=false)
Parameters:
conn - connection to be used to create the PreparedStatement
Parameters:
statementBuffer - the PreparedStatment, ready to be performed
throws:
SQLException - if a JDBC related error occurs |
| transformQuery | | protected Query transformQuery(Query query)(Code) | | Transforms the incoming
Query so that the
CoordinateSystem of all spatial arguments (BBOX, etc.)
in the
Filter match the SRS of the targeted
MappingGeometryField s.
NOTE: If this transformation can be performed by the backend (e.g. by Oracle Spatial), this method should be
overwritten to return the original input
Query .
Parameters:
query - query to be transformed query with spatial arguments transformed to target SRS |
| transformResult | | protected FeatureCollection transformResult(FeatureCollection fc, String targetSRS)(Code) | | Transforms the
FeatureCollection so that the geometries of all contained geometry properties use the
requested SRS.
Parameters:
fc - feature collection to be transformed
Parameters:
targetSRS - requested SRS transformed FeatureCollection |
