Class CompositeCstNodeImpl

A composite CST node contains other nodes, but no directly associated token.

The content array must not be modified directly; use the CstNodeBuilder methods instead to ensure that the container references of the child nodes are set correctly.

constructor

new CompositeCstNodeImpl(): CompositeCstNodeImpl

Returns CompositeCstNodeImpl

Inherited from AbstractCstNode.constructor

Properties

container

container: CompositeCstNode | undefined = undefined

The container node in the CST

content

content: CstNode[] = []

This array must not be modified directly; use the CstNodeBuilder methods instead to ensure that the container references of the child nodes are set correctly.

grammarSource

grammarSource: GrammarAST.AbstractElement | undefined = undefined

The grammar element from which this node was parsed

Accessors

astNode

get astNode(): AstNode
The AST node created from this CST node

Returns AstNode
Implementation of CompositeCstNode.astNode

Overrides AbstractCstNode.astNode
- Defined in packages/langium/src/parser/cst-node-builder.ts:320
set astNode(value: AstNode | undefined): void
The AST node created from this CST node
Parameters
- value: AstNode | undefined
Returns void
Implementation of CompositeCstNode.astNode

Overrides AbstractCstNode.astNode
- Defined in packages/langium/src/parser/cst-node-builder.ts:332

end

get end(): number
Returns number
Implementation of CompositeCstNode.end

Overrides AbstractCstNode.end
- Defined in packages/langium/src/parser/cst-node-builder.ts:348

hidden

get hidden(): boolean
Whether the token is hidden, i.e. not explicitly part of the containing grammar rule

Returns boolean
Implementation of CompositeCstNode.hidden

Overrides AbstractCstNode.hidden
- Defined in packages/langium/src/parser/cst-node-builder.ts:336

length

get length(): number
Returns number
Implementation of CompositeCstNode.length

Overrides AbstractCstNode.length
- Defined in packages/langium/src/parser/cst-node-builder.ts:344

offset

get offset(): number
Returns number
Implementation of CompositeCstNode.offset

Overrides AbstractCstNode.offset
- Defined in packages/langium/src/parser/cst-node-builder.ts:340

range

get range(): Range
Returns Range
Implementation of CompositeCstNode.range

Overrides AbstractCstNode.range
- Defined in packages/langium/src/parser/cst-node-builder.ts:352

root

get root(): RootCstNode
The root CST node.

The root is resolved by walking up the container chain on every access. Avoid repeated accesses in loops over many nodes of the same tree; resolve the root once instead.

Returns RootCstNode
Implementation of CompositeCstNode.root

Inherited from AbstractCstNode.root
- Defined in packages/langium/src/parser/cst-node-builder.ts:211

text

get text(): string
The actual text covered by this node.

The text is extracted from the document content on every access. When processing many nodes of the same tree, prefer resolving root.fullText once and slicing it with the nodes' offset and end values.

Returns string
Implementation of CompositeCstNode.text

Inherited from AbstractCstNode.text
- Defined in packages/langium/src/parser/cst-node-builder.ts:220
