public class NoLimitScannerContext
extends ScannerContext

This is a special ScannerContext subclass that is designed to be used globally when limits should not be enforced during invocations of InternalScanner.next(java.util.List) or InternalScanner.next(java.util.List).

Instances of NoLimitScannerContext are immutable after construction. Any attempt to change the limits or progress of a NoLimitScannerContext will fail silently. The net effect is that all limit checks will return false, thus indicating that a limit has not been reached.
