Net-OSLC-CM Perl Module

Simple Defects (SD) SD connectors Introduction to OSLC-CM Development goal Net-OSLC-CM Perl Module q  OSLC connector in SD q  Using and testing q  Making-up

Net-OSLC-CM

q  Standard Perl module

q  Helping implement a OSLC-CM Consumer


Example


use Net::OSLC::CM; my $oslccm = Net::OSLC::CM−>new( url => $self−>remote_url, username => $username, password => $password )); # Getting an array of changeRequests

my @results = $oslccm−>get_oslc_resources;


my @results = $oslccm−>changeRequests;

Résultat final

Detailed example


$oslccm−>url = "http://example.com"; $oslccm−>parser( Net::OSLC::CM::Parser−>new(cm => $oslccm) ); $oslccm−>create_catalog; $oslccm−>get_provider_catalog_resource; $oslccm−>get_service_providers; $oslccm−>get_changeRequests($oslccm−>providers); $oslccm−>load_changeRequests(); my @results = $oslccm−>changeRequests;
