Class GMLWriter

java.lang.Object

com.vividsolutions.jump.io.GMLWriter

All Implemented Interfaces:

JUMPWriter

public class GMLWriter
extends Object
implements JUMPWriter

GMLWriter is a JUMPWriter specialized to output GML.

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( , );
 

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

Method Detail

write

public void write(FeatureCollection featureCollection,
         DriverProperties dp)
           throws IllegalParametersException,
                  Exception

Main entry function - write the GML file.

Specified by:

write in interface JUMPWriter

Parameters:

featureCollection - features to write

dp - specify the 'OuputFile' and 'OuputTemplateFile'

Throws:

IllegalParametersException

Exception

write

public void write(FeatureCollection featureCollection,
         Writer writer)
           throws Exception

Actual evaluator/writer - you should have already called setOutputTemplate

Parameters:

featureCollection - features to write

writer - - where to send the output to

Throws:

Exception

safeXML

public static String safeXML(String s)

Convert an arbitary string into something that will not cause XML to gack. Ie. convert "<" to "<"

Parameters:

s - string to safe-ify

setOutputTemplate

public void setOutputTemplate(GMLOutputTemplate ot)

Attaches a GMLOuputTemplate

toString

protected String toString(Feature f,
              String column)

format

protected String format(Date date)

makeOutputTemplate

public static GMLOutputTemplate makeOutputTemplate(FeatureSchema fcmd)

given a FEatureSchema, make an output template in the JCS format

Parameters:

fcmd - input featureSchema

makeInputTemplate

public static String makeInputTemplate(FeatureSchema fcmd)

given a FeatureSchema, make a chunk of XML that represents a valid GMLInputTemplate for the JCS format. Used by makeOutputTemplate since the output template includes an inputtemplate.

Parameters:

fcmd - the featureSchema to describe
