Class GMLOutputTemplate

java.lang.Object

org.locationtech.jts.jump.io.GMLOutputTemplate

public class GMLOutputTemplate
extends Object

This class provides a parser for reading GMLOuputTemplates. This does NOT contain an evaluator for
taking the parsed GMLOutputTemplate and a featureCollection and producing properly
formatted output GML. Thats the GMLWriter class.


Most people will just use the load() function, but there is support for directly
constructing/modifying one. Your best bet for hand creating one is to make a String that
contains a GMLOutputTemplate then make a java.io.StringReader and passing it to the load()
method.
The valuators (things that look like "<%") are:
<%=GEOMETRY> - replace this with a GML represention of the geometry
<%=COLUMN > - replace this with the corresponding JCS column value
<%FEATURE> - this marks the start of a feature in the OutputTemplate
<%ENDFEATURE> - This marks the end of a feature in the OutputTempalte


Here's an example of how a simple GMLOutputTemplate is parsed by this class: for input like:
<?xml version='1.0' encoding='UTF-8'?>
<dataset...>
<schemaFeatures>
<gml:featureMember>
<% FEATURE %>
<Feature>
<featureType> <%=COLUMN featureType %> </featureType>
<property fme:name="ID"> <%=COLUMN ID %> </property>
<property fme:name="SITE"> <%=COLUMN SITE %> </property>
<property fme:name="gml2_coordsys"></property>
<gml:pointProperty>
<%=GEOMETRY %>
</gml:pointProperty>
</Feature>
<% ENDFEATURE %>
</gml:featureMember>
</dataFeatures>
</dataset>


headeText =

<?xml version='1.0' encoding='UTF-8'?>
<dataset...>
<schemaFeatures>
<gml:featureMember>

footerText =
</gml:featureMember>
</dataFeatures>
</dataset>


featureText[0] =
<Feature>
<featureType>

codingText[0] = "=COLUMN featureTtype"

featureText[1] =
</property>
<property fme:name="SITE">

codingText[1] = "=COLUMN ID"
