@LcdService(service=ILcdModelEncoder.class,
            priority=20000)
public class TLcdGML32ModelEncoder
extends ALcdXMLModelEncoder

This model encoder encodes Geography Markup Language (GML) version 3.2.

Output files

File	Description
.gml, .gml32, *.xml	GML 3.2 data file
*.xsd	Application schema (XML Schema)

Supported file transfer protocols

This model encoder supports all transfer protocols that are supported by the outputStreamFactory of this encoder.

Supported models for saving

This model encoder can save all models decoded by the TLcdGML32ModelDecoder and models having a TLcdGML32ModelDescriptor. These models are instances of TLcdGML32Model or TLcdGML32AbstractFeatureCollection. Model elements are instances of TLcdGML32AbstractFeature.

Supported models for exporting

This model encoder can save all models having ILcdShape/ILcdDataObject elements. Nested features are also supported.

The following shapes are supported:

Java class	GML geometry type
ILcdPoint	gml:PointType
ILcdPolyline	gml:LineStringType
ILcdCircle	gml:CurveType
ILcdCircleBy3Points	gml:CurveType
ILcdCircularArcBy3Points	gml:CurveType
ILcdCircularArcByBulge	gml:CurveType
ILcdCircularArcByCenterPoint	gml:CurveType
ILcdCircularArc	gml:CurveType
ILcdCompositeCurve	gml:CompositeCurveType
ILcdPolygon	gml:PolygonType
ILcdComplexPolygon	gml:SurfaceType
ILcdSurface	gml:SurfaceType
ILcdShapeList	gml:MultiGeometryType

The following feature classes are supported:

Java class	XSD type
Boolean	xsd:boolean
Byte	xsd:byte
Short	xsd:short
Integer	xsd:int
Long	xsd:long
Float	xsd:float
Double	xsd:double

Supported model references

This model encoder supports all model references which can be formatted by the TLcdOGCModelReferenceFormatter.

Useful settings

A default target namespace can be configured on this model encoder. This namespace will be the namespace of all the application schemas that are generated during export of non-GML32 models.

Sample code


 ILcdModelEncoder encoder = new TLcdGML32ModelEncoder();
 encoder.export(model, "world.gml32");

Thread safety

The encoding of models is thread-safe, as long as no properties are changed during the encoding.

Supported versions and specifications

GML 3.2.1

Known limitations

Since:: 9.0

    toString in class Object
  - getDefaultTargetNamespace
```
public String getDefaultTargetNamespace()

    the default namespace for generated application schemas, or null if a namespace is generated.
  - setDefaultTargetNamespace
```
public void setDefaultTargetNamespace(String aTargetNamespace)
```
    Sets the default target application schema namespace. This is the namespace in which all generated elements and types generated specifically for the exported document will be declared. If null (the default), a namespace will be generated.
    
    Parameters:
    
    aTargetNamespace - the default namespace for generated application schemas.
  - isAutoEncodeSchema
```
public boolean isAutoEncodeSchema()
```
    Returns true if the schema is automatically encoded when a model is encoded, false otherwise.
    
    Returns:
    
    true if the schema is automatically encoded when a model is encoded, false otherwise.
  - setAutoEncodeSchema
```
public void setAutoEncodeSchema(boolean aAutoEncodeSchema)
```
    Sets whether a schema is to be encoded automatically when a model is encoded. When set to true, this means that two output streams will be created when the save or export method is called, one for the destination file and one for the schema.
    
    Parameters:
    
    aAutoEncodeSchema - whether a schema is to be encoded automatically when a model is encoded.
  - createSchemaLocation
```
protected String createSchemaLocation(String aNamespaceURI,
                                      String aDefaultSchemaLocation,
                                      String aDestinationName)
```
    Returns a schema location for the specified namespace URI to be encoded in the "xsi:schemaLocations" attribute in the generated XML documents. The default implementation just returns the default location which is passed. This might be a local source however, which can be unwanted in some cases (e.g. a WFS server).
    
    Parameters:
    
    aNamespaceURI - the namespace URI for which to create a schema location.
    
    aDefaultSchemaLocation - the default schema location, if known by the encoder.
    
    aDestinationName - the name of the document being saved or exported, which will refer in its "xsi:schemaLocations" attribute to this schema location.
    
    Returns:
    
    a schema location for the specified namespace URI, which has a useful meaning in the encoded document.
  - canExport
```
public boolean canExport(ILcdModel aModel,
                         String aDestinationName)
```
    Description copied from interface: ILcdModelEncoder
    
    Returns whether this encoder can export the specified model to the specified destination. This method will typically check whether the contents of the specified model are compatible with the format this encoder is written for.
    
    Parameters:
    
    aModel - the model to be verified.
    
    aDestinationName - the location where the model should be exported to.
    
    Returns:
    
    true if this encoder can export the specified model to the specified location, false otherwise.
