CandidBaseVisitor<T> class

This class provides an empty implementation of CandidVisitor, which can be extended to create a visitor which only needs to handle a subset of the available methods.

T is the return type of the visit operation. Use void for operations with no return type.

Methods

aggregateResult(T? aggregate, T? nextResult) → T?

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() → T?

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, T? 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.
