Method Detail

getCoordinateSystem

public org.opengis.referencing.crs.CoordinateReferenceSystem getCoordinateSystem()

Description copied from interface: GeometryAttributeType

Retrieve the CS_CoordinateSystem used by this GeometryAttributeType.

OUT OF DATE: The class CoordinateSystem holds a GeometryFactory that is used for creating new content. By extension this includes the SRID, PercisionModel and CoordinateSequenceFactory information.

Specified by:

getCoordinateSystem in interface GeometryAttributeType

Returns:

CS_CoordinateSystem for this GeometryAttributeType

getGeometryFactory

public com.vividsolutions.jts.geom.GeometryFactory getGeometryFactory()

Description copied from interface: GeometryAttributeType

The Geometryfactory used for creating new content.

Replace with the following code:

 Map hints = new HashMap();
 hints.put( CoordinateReferneceSystem.class, type.getCoordinateSystem() ); 
 GeometryFactory gf = FactoryFinder.getGeometryFactory( Map hints );
 
 // You can now use gf create methods
 

Specified by:

getGeometryFactory in interface GeometryAttributeType

Returns:

GeometryFactory used for new Content

parse

public java.lang.Object parse(java.lang.Object value)
                       throws java.lang.IllegalArgumentException

Description copied from interface: AttributeType

Allows this AttributeType to convert an argument to its prefered storage type. If no parsing is possible, returns the original value. If a parse is attempted, yet fails (i.e. a poor decimal format) throw the Exception. This is mostly for use internally in Features, but implementors should simply follow the rules to be safe.

Specified by:

parse in interface AttributeType

Overrides:

parse in class DefaultAttributeType

Parameters:

value - the object to attempt parsing of.

Returns:

value converted to the preferred storage of this AttributeType. If no parsing was possible then the same object is returned.

Throws:

java.lang.IllegalArgumentException - if parsing is attempted and is unsuccessful.

duplicate

public java.lang.Object duplicate(java.lang.Object o)
                           throws IllegalAttributeException

Description copied from interface: AttributeType

Create a duplicate value of the passed Object. For immutable Objects, it is not neccessary to create a new Object.

Specified by:

duplicate in interface AttributeType

Overrides:

duplicate in class DefaultAttributeType

Returns:

A duplicated Object if the type is mutable or the same Object if it is immutable or null if the passed Object is null.

Throws:

IllegalAttributeException - if the Object cannot be duplicated.

getRestriction

public Filter getRestriction()

Description copied from interface: GeometryAttributeType

Restriction is assumed to be in agreement with Geometry class indicated.

Specified by:

getRestriction in interface GeometryAttributeType

Overrides:

getRestriction in class DefaultAttributeType
