GMLWriter (OpenJUMP 2.4.0 API)

java.lang.Object
- com.vividsolutions.jump.io.GMLWriter

All Implemented Interfaces:

JUMPWriter, TaskMonitorSupport

Direct Known Subclasses:

JMLWriter
```
public class GMLWriter
extends Object
implements JUMPWriter, TaskMonitorSupport
```
GMLWriter is a JUMPWriter specialized to output GML. TODO: use a proper XML framework, switch to XML1.1 which supports much broader range of unicode characters
DataProperties for the JCSWriter write(featureSchema,DataProperties) interface:

Parameter Meaning

OutputFile or DefaultValue File name for output .xml file

OutputTemplateFile File name for GMLOutputTemplate file

NOTE: If OutputTemplateFile is unspecified, one will be auto-created (the JCS format).

Programmer details:

This is usually called as follows:
```
    gmlWriter= new GMLWriter(); 
    gmlWriter.write( DriverProperites);
 
```
or:
```
    gmlWriter.setOutputTemplate( GMLOutputTemplate);
    gmlWriter.write( <writer>, <stream name>);
 
```
Also, the function "makeOutputTemplate()" is useful for autogenerating the JCS outputtemplate.

Output will be formed from the OutputTeplate like:
```
 headerText
 ==== This section repeated for each feature 
 featureText[0] <evaluate codeText[0]>
 featureText[1] <evaluate codeText[1]>
 ... 
 featureTextFooter
 ====
 footerText 
 
```
