Re: [Geotools-gt2-users] need to send featurecollection over network (need help fast)

[mounir y. <mou...@gm...>]

question 1: What does the assertEquals() and strip() methods do ?
And I want to send a feature collection with an OutputStream
(DataOutputStream or ObjectOutputStream) so should I do the following?


FeatureJSON fjson = new FeatureJSON();

StringWriter writer = new StringWriter();
fjson.writeFeatureCollection(collection(), writer); //question 2 -
does this take the collection
and return it as a string and put it in string writer ? If yes ! does
this mean that
I can simply send it as a string over the network ?

at the other end what should I read and how?
fjson.readFeatureCollection() ?
should I implement the collectionText() method ? if yes what does the
withBounds parameter mean ?

Thank you :) I hope the answer for these questions would help others :)
