Psych::Nodes::Sequence

This class represents a YAML sequence.

A YAML sequence is basically a list, and looks like this:

%YAML 1.1
---
- I am
- a Sequence

A YAML sequence may have an anchor like this:

%YAML 1.1
---
&A [
  "This sequence",
  "has an anchor"
]

A YAML sequence may also have a tag like this:

%YAML 1.1
---
!!seq [
  "This sequence",
  "has a tag"
]

This class represents a sequence in a YAML document. A Psych::Nodes::Sequence node may have 0 or more children. Valid children for this node are:
