SyntheticTemplateAst class abstract
An AST node that was created programmatically (not from parsed source).
Synthetic ASTs are useful for:
- Error fallback (parser can add nodes that were missing but expected)
- Testing (i.e. comparing actual parsed nodes to expected synthetic ones)
- Transformation (modifying an AST tree that originally was parsed)
- Implemented types
Constructors
- SyntheticTemplateAst()
-
Create a synthetic AST that has no origin from parsed source.
const
- SyntheticTemplateAst.from(TemplateAst? origin)
-
Create a synthetic AST that originated from another AST node.
