class Psych::Nodes::Sequence - RDoc Documentation

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

ANY

Any Styles, emitter chooses

BLOCK

Block style sequence

FLOW

Flow style sequence

anchor[RW]

The anchor for this sequence (if any)

implicit[RW]

Is this sequence started implicitly?

style[RW]

The sequence style used

tag[RW]

The tag name for this sequence (if any)

Create a new object representing a YAML sequence.

anchor is the anchor associated with the sequence or nil. tag is the tag associated with the sequence or nil. implicit a boolean indicating whether or not the sequence was implicitly started. style is an integer indicating the list style.

See Psych::Handler#start_sequence

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