[udig-devel] Layer Attribute Query

[Andy Cox]

Jesse,

 

Thanks for the pointers. Is there an easy way to search the e-mail list
archives for previous posts as you suggest below ?

 

Cheers

Andy

Hi,

 

You'll want to look at the code snippets I sent in a previous email and the
Geotools Filters and JTS operations.

 

Here's a tip:

 

ff = FilterFactoryFinder.createFilterFactory()

idFilter1 = ff.createFidFilter( id1 );

 

idFilter2 = ff.createFidFilter( id2 );

 

or = ff.createLogicFilter( FilterType.LOGIC_OR )

 

or.addFilter( idFilter1 );

or.addFilter( idFilter2 );

 

Something like that.

 

Jesse

Hello,

I have a polygon layer which has about 10 polygons. I want to get access to
two specific polygons based on attribute query (e.g. their IDs). Then I want
to perform a Boolean spatial intersection to find out they intersect. Does
anyone have any pointers to where I can find some info on this?

Any help greatly appreciated.

Thanks
Andy
