class YAML::Nodes::Builder

Overview

Builds a tree of YAML nodes.

This builder is similar to YAML::Builder, but instead of directly emitting the output to an IO it builds a YAML document tree in memory.

All "emitting" methods support specifying a "reference" object that will be associated to the emitted object, so that when that reference object is emitted again an anchor and an alias will be created. This generates both more compact documents and allows handling recursive data structures.
