Remarks

An immutable set that implements IPGTerminalSet so that it can be used by LLParserGenerator.

This class effectively represents any type of set. It is used by GeneralCodeGenHelper.

Member Function Documentation

IPGTerminalSet Loyc.LLParserGenerator.PGNodeSet.UnionCore ( IPGTerminalSet other )

inline

Merges two sets.

Returns: The combination of the two sets, or null if other's type is not supported.

IPGTerminalSet Loyc.LLParserGenerator.PGNodeSet.WithEOF ( bool wantEOF = true )

inline

Adds or removes EOF from the set. If the set doesn't change, this method may return this.
