Class NullTypeBinding

Object
  AbstractSimpleBinding
      NullTypeBinding

All Implemented Interfaces:

Binding, SimpleBinding

public class NullTypeBinding
extends AbstractSimpleBinding

Binding object for the type http://www.opengis.net/gml:NullType.

  <code>
  <simpleType name="NullType">
      <annotation>
          <documentation>
          If a bounding shape is not provided for a feature collection, 
          explain why. Allowable values are:
          innapplicable - the features do not have geometry
          unknown - the boundingBox cannot be computed
          unavailable - there may be a boundingBox but it is not divulged
          missing - there are no features
        </documentation>
      </annotation>
      <restriction base="string">
          <enumeration value="inapplicable"/>
          <enumeration value="unknown"/>
          <enumeration value="unavailable"/>
          <enumeration value="missing"/>

Constructor Detail

NullTypeBinding

public NullTypeBinding()

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.

getExecutionMode

public int getExecutionMode()

Description copied from class: AbstractSimpleBinding

This implementation returns Binding.AFTER.

Subclasses should override to change this behaviour.

Specified by:

getExecutionMode in interface Binding

Overrides:

getExecutionMode in class AbstractSimpleBinding

Returns:

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

See Also:

Binding.AFTER, Binding.BEFORE, Binding.OVERRIDE

parse

public Object parse(InstanceComponent instance,
                    Object value)
             throws Exception

Specified by:

parse in interface SimpleBinding

Overrides:

parse in class AbstractSimpleBinding

Parameters:

instance - The component 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

encode

public String encode(Object object,
                     String value)
              throws Exception

Description copied from class: AbstractSimpleBinding

Performs the encoding of the object as a String.

Specified by:

encode in interface SimpleBinding

Overrides:

encode in class AbstractSimpleBinding

Parameters:

object - The object being encoded, never null.

value - The string returned from another binding in the type hierachy, which could be null.

Returns:

A String representing the object.

Throws:

Exception
