Methods

aggregateResult(dynamic aggregate, dynamic nextResult) → dynamic
Aggregates the results of visiting multiple children of a node. After either all children are visited or {@link #shouldVisitNextChild} returns false, the aggregate value is returned as the result of {@link #visitChildren}.
inherited
defaultResult() → dynamic
Gets the default value returned by visitor methods. This value is returned by the default implementations of {@link #visitTerminal visitTerminal}, {@link #visitErrorNode visitErrorNode}. The default implementation of {@link #visitChildren visitChildren} initializes its aggregate result to this value.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
shouldVisitNextChild(RuleNode node, dynamic currentResult) → bool
This method is called after visiting each child in {@link #visitChildren}. This method is first called before the first child is visited; at that point currentResult will be the initial value (in the default implementation, the initial value is returned by a call to {@link #defaultResult}. This method is not called after the last child is visited.
inherited
toString() → String
A string representation of this object.

visitChildren(RuleNode node) → dynamic
{@inheritDoc}
inherited
visitComment(CommentContext ctx) → dynamic
The default implementation returns the result of calling visitChildren on ctx.
inherited
visitEnv(EnvContext ctx) → dynamic
The default implementation returns the result of calling visitChildren on ctx.
inherited
visitErrorNode(ErrorNode node) → dynamic
{@inheritDoc}
inherited
visitKey(KeyContext ctx) → dynamic
The default implementation returns the result of calling visitChildren on ctx.
inherited
visitLine(LineContext ctx) → void
The default implementation returns the result of calling visitChildren on ctx.
override
visitString(StringContext ctx) → dynamic
The default implementation returns the result of calling visitChildren on ctx.
inherited
visitTerminal(TerminalNode node) → dynamic
{@inheritDoc}
inherited
visitValue(ValueContext ctx) → dynamic
The default implementation returns the result of calling visitChildren on ctx.
