Class IsRemovedCoalescingOperator

java.lang.Object

org.ek9lang.compiler.phase1.IsRemovedCoalescingOperator

All Implemented Interfaces:

Predicate<org.antlr.v4.runtime.Token>

final class IsRemovedCoalescingOperator
extends Object
implements Predicate<org.antlr.v4.runtime.Token>

THE "is this token one of the removed coalescing operators?" - <=?, >=? (E01095), ?? or ??= (E01096), all reported by RemovedCoalescingOperatorOrError. A phase-1 check that would report AT such a token for another reason (E08269 reports a coalescing operand from the enclosing expression, before this one is entered) asks this and leaves the place to that error, so the first error at the place says what is wrong. Was RemovedCoalescingOperatorOrError.isRemoved (no-statics lane P1, 2026-10-29).
