# class 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:

- `Psych::Nodes::Sequence`

- `Psych::Nodes::Mapping`

- `Psych::Nodes::Scalar`

- `Psych::Nodes::Alias`

    def initialize anchor = nil, tag = nil, implicit = true, style = BLOCK
      super()
