layer to a file. The code can be found in the repository under community/jesse
I believe.
As for what you are doing wrong and how we should be doing it right.... I'm not
100% sure to be perfectly honest with you. What happens if you do a getString
hello,
In order to have a look to sld xml file, I did that :
public static void dumpStyle(Style style,Writer writer )
{
if (writer == null)
{
dumpStyle(style);
return;
}
SLDContent styleContent = new SLDContent();
try {
// save the state of the style
XMLMemento memento = XMLMemento.createWriteRoot
("styleEntry"); //$NON-NLS-1$
styleContent.save(memento, style);
memento.save(writer);
writer.close();
} catch (IOException e) {
System.out.println( "dumpStyle");
e.printStackTrace();
}
}
and that
public static void dumpStyle(Style style )
{
SLDContent styleContent = new SLDContent();
try {
// save the state of the sty le
XMLMemento memento = XMLMemento.createWriteRoot
("styleEntry"); //$NON-NLS-1$
styleContent.save(memento, style);
StringWriter writer = new StringWriter();
memento.save(writer);
System.out.println( writer.getBuffer().toString());
writer.close();
} catch (IOException e) {
System.out.println( "dumpStyle");
e.printStackTrace();
}
}
the result (the begining of the file) is :
<?xml version="1.0" encoding="UTF-8"?>
<styleEntry type="SLDStyle" version="1.0"><?xml version="
1.0" encoding="UTF-8"?><sld:NamedLayer
gml"><sld:UserStyle><sld:Name>Default Styler</
sld:Name><sld:Title>Default Styler</
sld:Title><sld:Abstract></
sld:Abstract><sld:FeatureTypeStyle><sld:FeatureTypeName>F
eature</
sld:FeatureTypeName><sld:Rule><sld:Name>name</
sld:Name><sld:Abstract>Abstract</
sld:Abstract><sld:Title>title</
not a good result definitly...
i tried to understand why and fall into SLDContent :
public void save( IMemento momento, Object value ) {
Style style = (Style) value;
// serialize out the style objects
SLDTransformer sldWriter = new SLDTransformer();
String out = ""; //$NON-NLS-1$
try {
out = sldWriter.transform(style);
} catch (TransformerException e) {
SLDPlugin.log(null, e);
e.printStackTrace();
} catch (Exception e) {
SLDPlugin.log(null, e);
}
momento.putTextData(out);
momento.putString("type", "SLDStyle"); //$NON-NLS-1$ //$NON-
NLS-2$
momento.putString("version", "1.0"); //$NON-NLS-1$ //$NON-
NLS-2$
}
when you use
-momento.putTextData(out);
with an XMLMemento, the DOMWriter use getEscaped() function if it
crosses a TEXT element
so the < and the > are trashed into > and <
...
As a side effect when i open the style editor i got this eerror :
Unable to create view: org.xml.sax.SAXParseException: Element type
"ogc:PropertyIsLike" must be followed by either attribute
specifications, ">" or "/>".
