◆ equals()

virtual bool UnOpExpr::equals	(	const Expr *	expr,
		bool	exact = `false`
	)		const

overridevirtualnoexcept

Checks if this expression and expr have the same structure, Every expression has the same structure as '_' (it's called ANY after all).

Parameters

expr	The expression to compare to this.
exact	If true any must equal any and nothing else. Otherwise any is equal to anyting else.

Reimplemented from Expr.

overridevirtualnoexcept

Evaluates expression one time.

Parameters

gc
env	Environment for accessing variables.

Reimplemented from Expr.

virtual Expr* UnOpExpr::optimize ( GCMain & gc )

overridevirtualnoexcept

Returns: Returns an optimized version of this expression. If nothing was optimized, returns itself.

Reimplemented from Expr.
