Classes

Serializer.YamlAlias

This class represents a YAML alias. An alias node is denoted by the * indicator. The alias refers to the most recent preceding node having the same anchor.

Members

Serializer.YamlDocument

This class represents a YAML document. A YAML document starts with the sequence --- and ends with an optional sequence ... or with the begining of the next document or the end of the stream. Each document is completely independent from the rest.

Members

Modifiers	Member	Description
