                          <documentation>GML supports two different ways to specify the control points of a curve segment.
  1. A sequence of "pos" (DirectPositionType) or "pointProperty" (PointPropertyType) elements. "pos" elements are control points that are only part of this curve segment, "pointProperty" elements contain a point that may be referenced from other geometry elements or reference another point defined outside of this curve segment (reuse of existing points).
  2. The "posList" element allows for a compact way to specifiy the coordinates of the control points, if all control points are in the same coordinate reference systems and belong to this curve segment only. The number of direct positions in the list must be at least three.</documentation>

Constructor Detail

ArcStringTypeBinding

public ArcStringTypeBinding(GeometryFactory gFactory,
                            CoordinateSequenceFactory csFactory,
                            ArcParameters arcParameters)

Method Detail

getTarget

public QName getTarget()

Specified by:

getTarget in interface Binding

Returns:

The qualified name of the target for the binding.

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.

See Also:

Binding.AFTER, Binding.BEFORE, Binding.OVERRIDE

getType

public Class getType()

Specified by:

getType in interface Binding

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.

getProperty

public Object getProperty(Object object,
                          QName name)
                   throws Exception

Description copied from class: AbstractComplexBinding

Subclasses should override this method if need be, the default implementation returns null.

Specified by:

getProperty in interface ComplexBinding

Overrides:

getProperty in class AbstractComplexBinding

Parameters:

object - The object being encoded.

name - The name of the property to obtain.

Returns:

The value of the property, or null.

Throws:

Exception

ComplexBinding.getProperty(Object, QName)

compareTo

public int compareTo(Object o)

Specified by:

compareTo in interface Comparable
