Indicates whether applying repetition to the expression invalidates the boundedness computation.
Indicates whether applying repetition to the expression invalidates the boundedness computation. This generally indicates that the expression may match a zero-repetition ({0, n} or ?).
This is used to determine boundedness of enclosing expressions.
