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

UnionCore()

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.

Implements Loyc.LLParserGenerator.IPGTerminalSet.

WithEOF()

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.

Implements Loyc.LLParserGenerator.IPGTerminalSet.
