ErrorNodeImpl class

Represents a token that was consumed during resynchronization rather than during a valid match operation. For example, we will create this kind of a node during single token insertion and deletion as well as during "consume until error recovery set" upon no viable alternative exceptions.

Properties

childCount → int
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
parent ↔ ParseTree?
covariantgetter/setter pairinherited
payload → Token?
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
sourceInterval → Interval
Return an Interval indicating the index in the TokenStream of the first and last token associated with this subtree. If this node is a leaf, then the interval represents a single token and has interval i..i for token index i.
no setterinherited
symbol ↔ Token
getter/setter pairinherited
text → String?
Return the combined text of all leaf nodes. Does not get any off-channel tokens (if any) so won't return whitespace and comments if they are sent to parser on hidden channel.

The ParseTreeVisitor needs a double dispatch method. */
override
getChild<T>(int i) → ParseTree?

isErrorNode() → bool
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.

toString() → String
A string representation of this object.
inherited
toStringTree({Parser? parser}) → String
Specialize toStringTree so that it can print out more information based upon the parser.
