NAME
Forest::Tree::Builder - An abstract role for bottom up tree readerSYNOPSIS
package MyBuilder; use Moose; with qw(Forest::Tree::Builder); # implement required builder: sub _build_subtrees { return [ $self->create_new_subtree( ... ), # probably a recursive process ]; } my $builder = MyBuilder->new( tree_class => ..., ... ); my $tree = $builder->tree;
DESCRIPTION
Forest::Tree::Builder replaces Forest::Tree::Loader and Forest::Tree::Reader with a bottom up construction approach, which is also suitable for constructing Forest::Tree::Pure derived trees without excessive cloning.It provides a declarative API instead of an imperative one, where "tree" is lazily constructed on the first use, instead of being constructed immediately and ``filled in'' by the "load" method.
METHODS
- create_new_subtree
- Implemented by Forest::Tree::Constructor
- _build_tree
- Constructs a root node by using the top level "subtrees" list as the children.
- _build_subtrees
- Build the subtrees.
Abstract method that should return an array ref of Forest::Tree::Pure derived objects.
