Method: Puppet::Parser::Compiler#evaluate_node_classes

Defined in:
lib/puppet/parser/compiler.rb

#evaluate_node_classes ⇒ Object

Evaluate all of the classes specified by the node. Classes with parameters are evaluated as if they were declared. Classes without parameters or with an empty set of parameters are evaluated as if they were included. This means classes with an empty set of parameters won’t conflict even if the class has already been included.
