class AlternationCapture : Node.ParserCapture

A ParserCapture subclass produced by AlternationElement.

This capture records which branch of an alternation was successfully matched.

Properties

val isAlternation: Boolean

Returns true if this node is an AlternationCapture.

Link copied to clipboard
val isRepeatable: Boolean

Returns true if this node is a RepeatableCapture.

Link copied to clipboard
open val nodes: <Error class: unknown class>

Returns only the child subnodes, excluding tokens.

open lateinit var stack: List<ParserContext.Frame>

The parser stack frames active when this Node was created.

Link copied to clipboard
open val tokens: <Error class: unknown class>

Returns only the tokens directly captured by this node, excluding tokens captured by subnodes.
