Hi Kencana,,

This function is to release or close the the feature reader returned by the
feature property, if the command is of type insert features. If we don't
close the feature readers properly, the application could hang. 

I havent worked in php...so pardon me if im wrong...but isnt it possible to
write functions there...? So u can just include the same code as a function
rt?

Something like:
<?php function ReleaseReader($MgPropertyCollection,$
MgFeatureCommandCollection)
{
}
?>


Regards
Farah

Hi Farah,

Thanks a lot for the explanation.
how ever i got one doubt.
can I know this code is for?
void ReleaseReader(MgPropertyCollection res, MgFeatureCommandCollection 
commands) throws MgException
{
    if(res == null)
        return;

    for(int i = 0; i < res.GetCount(); i++)
    {
        MgFeatureCommand cmd = commands.GetItem(i);
        if(cmd instanceof MgInsertFeatures)
        {
            MgFeatureProperty resProp = (MgFeatureProperty)res.GetItem(i);
            if(resProp != null)
            {
                MgFeatureReader reader = 
(MgFeatureReader)resProp.GetValue();
                if(reader == null)
                    return;
                reader.Close();
            }
        }
    }
}

do you have any idea how it done in PHP?

Regards,
Kencana
