Methods

`Protected`createReferencesToAttribute

createReferencesToAttribute(
ruleOrAction: GrammarAST.AbstractParserRule | GrammarAST.Action,
attribute: GrammarAST.TypeAttribute,
): ReferenceDescription[]
Parameters
- ruleOrAction: GrammarAST.AbstractParserRule | GrammarAST.Action
- attribute: GrammarAST.TypeAttribute
Returns ReferenceDescription[]
- Defined in packages/langium/src/grammar/references/grammar-references.ts:70

`Protected`findActionDeclaration

findActionDeclaration(
action: GrammarAST.Action,
featureName?: string,
): GrammarAST.TypeAttribute | undefined
Parameters
- action: GrammarAST.Action
- OptionalfeatureName: string
Returns GrammarAST.TypeAttribute | undefined
- Defined in packages/langium/src/grammar/references/grammar-references.ts:160

`Protected`findAssignmentDeclaration

findAssignmentDeclaration(
assignment: GrammarAST.Assignment,
): AstNode | undefined
Parameters
- assignment: GrammarAST.Assignment
Returns AstNode | undefined
- Defined in packages/langium/src/grammar/references/grammar-references.ts:137

findDeclarationNodes

findDeclarationNodes(sourceCstNode: CstNode): CstNode[]
If the CstNode is a reference node the target CstNodes will be returned. If the CstNode is a significant node of the CstNode this CstNode will be returned.
Parameters
- sourceCstNode: CstNode
  CstNode that points to a AstNode
Returns CstNode[]
Inherited from DefaultReferences.findDeclarationNodes
- Defined in packages/langium/src/references/references.ts:148

findDeclarations

findDeclarations(sourceCstNode: CstNode): AstNode[]
If the CstNode is a reference node the target AstNodes will be returned. If the CstNode is a significant node of the CstNode this AstNode will be returned.
Parameters
- sourceCstNode: CstNode
  CstNode that points to a AstNode
Returns AstNode[]
Overrides DefaultReferences.findDeclarations
- Defined in packages/langium/src/grammar/references/grammar-references.ts:25

findReferences

findReferences(
targetNode: AstNode,
options: FindReferencesOptions,
): Stream<ReferenceDescription>
Finds all references to the target node as references (local references) or reference descriptions.
Parameters
- targetNode: AstNode
  Specified target node whose references should be returned
- options: FindReferencesOptions
Returns Stream<ReferenceDescription>
Overrides DefaultReferences.findReferences
- Defined in packages/langium/src/grammar/references/grammar-references.ts:41

`Protected`getSelfNodes

getSelfNodes(node: AstNode): AstNode[]
Returns all self-references for the specified node. Since the node can be part of a multi-reference, this method returns all nodes that are part of the same multi-reference.
Parameters
- node: AstNode
Returns AstNode[]
Inherited from DefaultReferences.getSelfNodes
- Defined in packages/langium/src/references/references.ts:113

`Protected`getSelfReferences

getSelfReferences(targetNode: AstNode): ReferenceDescription[]
Parameters
- targetNode: AstNode
Returns ReferenceDescription[]
Inherited from DefaultReferences.getSelfReferences
- Defined in packages/langium/src/references/references.ts:173
