class Puppet::Parser::AST::ASTArray

The basic container class. This object behaves almost identically to a normal array except at initialization time. Note that its name is ‘AST::ASTArray’, rather than plain ‘AST::Array’; I had too many bugs when it was just ‘AST::Array’, because things like ‘object.is_a?(Array)’ never behaved as I expected.

def evaluate(scope)
  result = []
  @children.each do |child|
    # Skip things that respond to :instantiate (classes, nodes,
    # and definitions), because they have already been
    # instantiated.
    if !child.respond_to?(:instantiate)
      item = child.safeevaluate(scope)
      if !item.nil?
        # nil values are implicitly removed.
