Puppet::Pops::Types::TypeParser#parse can be used to get a data type object
given a
type expressed as in the puppet language. As an example - this:
tparser = Puppet::Pops::Types::TypeParser.singleton
t = tparser.parse(‘Array[String]’, scope)
would assign a data type of Array type accepting String values to the
variable t.
An alternative is to use the Puppet::Pops::Types::TypeFactory to create
the same Array[String] datatype:
tf = Puppet::Pops::Types::TypeFactory
t = tf.array_of(tf.string)
Hope those help in the future
