sourceInterval property
Interval
sourceInterval
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.
An interval of i..i-1 indicates an empty interval at position i in the input stream, where 0 <= i <= the size of the input token stream. Currently, the code base can only have i=0..n-1 but in concept one could have an empty interval after EOF.
If source interval is unknown, this returns {@link Interval#INVALID}.
As a weird special case, the source interval for rules matched after EOF is unspecified.
Implementation
Interval get sourceInterval;
