Lookup a variable in a remote namespace.
|
|
|
|
For example:
|
|
|
|
$foo = getvar('site::data::foo')
|
|
# Equivalent to $foo = $site::data::foo
|
|
|
|
This is useful if the namespace itself is stored in a string:
|
|
|
|
$datalocation = 'site::data'
|
|
$bar = getvar("${datalocation}::bar")
|
|
# Equivalent to $bar = $site::data::bar
|
|
ENDHEREDOC
|
|
|
|
unless args.length == 1
|
|
raise Puppet::ParseError, ("getvar(): wrong number of arguments (#{args.length}; must be 1)")
|
|
end
|
|
|
|
self.lookupvar("#{args[0]}")
|
|
|
|
end
|
|
|
|
end
