type CalcLexer 

type CalcLexer struct {
	*antlr.BaseLexer
	// contains filtered or unexported fields
}

func NewCalcLexer 

func NewCalcLexer(input antlr.CharStream) *CalcLexer

NewCalcLexer produces a new lexer instance for the optional input antlr.CharStream.

The *CalcLexer instance produced may be reused by calling the SetInputStream method. The initial lexer configuration is expensive to construct, and the object is not thread-safe; however, if used within a Golang sync.Pool, the construction cost amortizes well and the objects can be used in a thread-safe manner.

type CalcListener 

type CalcListener interface {
	antlr.ParseTreeListener

	// EnterStart is called when entering the start production.
	EnterStart(c *StartContext)

	// EnterNumber is called when entering the Number production.
	EnterNumber(c *NumberContext)

	// EnterMulDiv is called when entering the MulDiv production.
	EnterMulDiv(c *MulDivContext)

	// EnterAddSub is called when entering the AddSub production.
	EnterAddSub(c *AddSubContext)

	// EnterParens is called when entering the Parens production.
	EnterParens(c *ParensContext)

	// ExitStart is called when exiting the start production.
	ExitStart(c *StartContext)

	// ExitNumber is called when exiting the Number production.
	ExitNumber(c *NumberContext)

	// ExitMulDiv is called when exiting the MulDiv production.
	ExitMulDiv(c *MulDivContext)

	// ExitAddSub is called when exiting the AddSub production.
	ExitAddSub(c *AddSubContext)

	// ExitParens is called when exiting the Parens production.
	ExitParens(c *ParensContext)
}

CalcListener is a complete listener for a parse tree produced by CalcParser.

type CalcParser 

type CalcParser struct {

func NewCalcParser 

func NewCalcParser(input antlr.TokenStream) *CalcParser

NewCalcParser produces a new parser instance for the optional input antlr.TokenStream.

The initial parser configuration is expensive to construct, and the object is not thread-safe; however, if used within a Golang sync.Pool, the construction cost amortizes well and the objects can be used in a thread-safe manner.
