public class SpatialDomainTypeBinding
extends AbstractComplexBinding

Binding object for the type http://www.opengis.net/wcs:SpatialDomainType.

  
  <complexType name="SpatialDomainType">
      <annotation>
          <documentation>Defines the spatial domain of a coverage offering. A server shall describe the spatial domain by its edges, using one or more gml:Envelope elements. The gml:EnvelopeWithTimePeriod element may be used in place of gml:Envelope, to add the time bounds of the coverage offering. Each of these elements describes a bounding box defined by two points in space (or two positions in space and two in time). This bounding box could simply duplicate the information in the lonLatEnvelope of CoverageOfferingBrief; but the intent is to describe the locations in more detail (e.g., in several different CRSs, or several rectangular areas instead of one overall bounding box).

  In addition, a server can describe the internal grid structure of a coverage offering, using a gml:Grid (or gml:RectifiedGrid) in addition to a gml:Envelope. This element can help clients assess the fitness of the gridded data for their use (e.g. its native resolution, inferred from the offsetVector of a gml:RectifiedGrid), and to formulate grid coverage requests expressed in the internal grid coordinate reference system.

  Finally, a server can describe the spatial domain by means of a (repeatable) gml:Polygon, representing the polygon(s) covered by the coverage spatial domain. This is particularly useful for areas that are poorly approximated by a gml:Envelope (such as satellite image swaths, island groups, other non-convex areas). </documentation>

Constructor Detail

SpatialDomainTypeBinding

public SpatialDomainTypeBinding()

Method Detail

getTarget

public QName getTarget()

Returns:

The qualified name of the target for the binding.

getType

public Class getType()

Returns:

The java type this binding maps to.

parse

public Object parse(ElementInstance instance,
                    Node node,
                    Object value)
             throws Exception

Specified by:

parse in interface ComplexBinding

Overrides:

parse in class AbstractComplexBinding

Parameters:

instance - The element being parsed.

node - The node in the parse tree representing the element being parsed.

value - The result of the parse from another strategy in the type hierarchy. Could be null if this is the first strategy being executed.

Returns:

The parsed object, or null if the component could not be parsed.

Throws:

Exception - Strategy objects should not attempt to handle any exceptions.

getExecutionMode

public int getExecutionMode()

Description copied from class: AbstractComplexBinding

This implementation returns Binding.OVERRIDE.

Subclasses should override to change this behaviour.

Specified by:

getExecutionMode in interface Binding

Overrides:

getExecutionMode in class AbstractComplexBinding

Returns:

The execution mode of the binding, one of the constants AFTER, BEFORE, or OVERRIDE.
