>> fileset::to-string(id,separator) - returns a list of files from the fileset 'id' separated by 'separator'
Very happy with this naming here. -Peter -----Original Message----- From: Jaroslaw Kowalski [mailto:[EMAIL PROTECTED] Sent: Friday, March 19, 2004 1:01 PM To: Ian MacLean; Horsfield, Peter A Cc: [EMAIL PROTECTED] Subject: Re: [nant-dev] New to the list OK. I'd like to gather current ideas (with some minor modifications) with one-line summaries: fileset::exists(id) - checks whether fileset named "id" is defined in current project fileset::get-file-count(id) - returns the number of files matched by the fileset "id" fileset::is-empty(id) - checks whether fileset named "id" matches zero files (a shortcut function - same thing can be achieved by fileset::get-file-count(id)=0) fileset::get-file-name(id,n) - returns the n-th file from the fileset (according to some ordering) fileset::to-string(id,separator) - returns a list of files from the fileset 'id' separated by 'separator' fileset::contains(id,filename) - checks whether the fileset 'id' contains file 'filename' Any corrections or new ideas ?
