Overview
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 Sequence
node may have 0 or more children. Valid children for this node are:
Constant Summary
-
ANY =
Any Styles, emitter chooses
0
-
BLOCK =
Block style sequence
1
-
FLOW =
Flow style sequence
2
