Public Instance Methods

evaluate(scope) click to toggle source

we're returning self here to wrap the regexp and to be used in places where a string would have been used, without modifying any client code. For instance, in many places we have the following code snippet:

val = @val.safeevaluate(@scope)
if val.match(otherval)
    ...
end

this way, we don't have to modify this test specifically for handling regexes.

   # File lib/puppet/parser/ast/leaf.rb

72   self
