Hi,
I have a question with respect to org.opengis.filter.Filter.
My simple feature has a property XXX which is a JAVA class.
In a filter expression I want to compare one of the java bean
properties of this java class against a literal.
Example
=======
class A
{
boolean selected = ...
public boolean isSelected() { return selected; }
}
// building features
{
SimpleFeatureTypeBuilder builder = new SimpleFeatureTypeBuilder();
...
builder.nillable(false).add("XXX", A.class);
SimpleFeatureType type = builder.buildFeatureType();
SimpleFeatureBuilder featureBuilder = new SimpleFeatureBuilder(type);
...
featureBuilder.add(new A());
}
// filtering
{
FilterFactory2 filterFactory = CommonFactoryFinder.getFilterFactory2();
// this doesn't work
Filter filter = filterFactory.equals
( filterFactory.property("XXX")
, filterFactory.literal(true)));
// this doesn't work too
Filter filter = filterFactory.equals
( filterFactory.property("XXX.selected")
, filterFactory.literal(true)));
}
What is the right way to filter for all features which have a property "XXX"
whose value "selected" is "true"?
Thank you
Michael
