BitSet Class

Namespace: Stimulsoft.Data.Expressions.Antlr.Runtime

A stripped-down version of org.antlr.misc.BitSet that is just good enough to handle runtime requirements such as FOLLOW sets for automatic error recovery.

Constructors

Constructor Description
constructor(number nbits) Construct a bitset given the size

constructor(nbits: number)

Construct a bitset given the size

Parameters

  • nbits (number) — The size of the bitset in bits
