Expand description

Typed views over the syntax tree.

Each type wraps a SyntaxNode of one kind. Accessors return None when the source is incomplete, so they work on trees with errors too.

Structs§

Alias: as name
ArgumentList
ConceptMap: conceptmap "url" { … }
ConceptMapCode: s:male
ConceptMapEntry: s:male - t:M
ConceptMapPrefix: prefix s = "url"
ConceptMapUnmapped: unmapped for s = provided
ConstantDeclaration: let name = expression;
DefaultClause: default (expression), or the legacy default "value".
DependentClause: then Group(a, b) { … }
Expr: Any FHIRPath expression node.
Group: group Name(…) extends Base <<types>> { … }
ImportsDeclaration: imports "url"
Invocation: name(arguments): a transform or a group call.
Literal: A literal token: string, number, boolean, date or time.
MapDeclaration: map "url" = "name"
Metadata: /// key = value
Parameter: source src : Type
ParameterList
QualifiedName: a.b.c
Rule: sources -> targets then … "name";
RuleBlock: { rule; … }
Source: One source of a rule.
SourceFile: A whole FML document.
Target: One target of a rule.
TypeAnnotation: : Type
UsesDeclaration: uses "url" alias Name as source

Enums§

GroupTypeMode: The type mode of a group: whether it is the default mapping for its types.
ListMode: A source or target list mode.
ModelMode: How a map uses a structure.
ParameterMode: Whether a group parameter is an input or an output.
TransformValue: The value a target is set to.

Traits§

AstNode: A typed view of a syntax node.

Functions§

name_text: The name a token spells: the identifier, or the content of a `delimited` identifier.
unescape: Removes the quotes from a string or delimited identifier and resolves escape sequences.
