Config::AST::Root(3) |
Config::AST::Root - root of the abstract syntax tree
An auxiliary class representing the root of the abstract syntax tree. It is
necessary because the tree itself forms a circular structure (due to the
root attribute of Config::AST::Node::Section). Without this
intermediate class (if root pointed to Config::AST itself), the
structure would have never been destroyed, because each element would remain
referenced at least once.
$ci is one to enable case-insensitive keyword lookup, and 0
otherwise.
Converts the string $name to a form suitable for lookups,
in accordance with the _ci attribute.
Destroys the underlying syntax tree.
Returns the root node of the tree, initializing it if necessary.
Returns true if the tree is empty.
