ESCGrammarExprs.Binary

Description

Represents a binary expression; that is, an expression that requires two operands (a left-hand side, LHS, and a right-hand side, RHS) and an operator that takes both operands as input. Examples include addition, subtraction.

Members

Methods

init

func init(left: ESCGrammarExpr, operator: ESCToken, right: ESCGrammarExpr) -> void

Initialization method. Must be called after instantiation.

Parameters

Name	Type	Description	Required?
left	`ESCGrammarExpr`	Left-hand operand expression.	yes
operator	`ESCToken`	Token representing the operator applied to the operands.	yes
right	`ESCGrammarExpr`	Right-hand operand expression.	yes

Returns

Returns nothing.

get_left

func get_left() -> ESCGrammarExpr

The LHS of the binary expression.

Parameters

None.

Returns

Returns the LHS of the binary expression. (ESCGrammarExpr)

get_right

func get_right() -> ESCGrammarExpr

The RHS of the binary expression.

Parameters

None.

Returns

Returns the RHS of the binary expression. (ESCGrammarExpr)

get_operator

func get_operator() -> ESCToken

The operator the binary expression.

Parameters

None.

Returns

Returns the operator the binary expression. (ESCToken)

accept

func accept(visitor: Variant) -> Variant

Method to invoke visitor-specific code.

Parameters

Name	Type	Description	Required?
visitor	`Variant`	Visitor instance invoked to process this expression.	yes

Returns

Returns the result of visiting this binary expression. (Variant)
