Constructor & Destructor Documentation

LambdaCapture()

LambdaCapture::LambdaCapture	(	SourceLocation	Loc,
		bool	Implicit,
		LambdaCaptureKind	Kind,
		ValueDecl *	Var = nullptr,
		SourceLocation	EllipsisLoc = SourceLocation()
	)

Create a new capture of a variable or of this.

Parameters

Loc	The source location associated with this capture.
Kind	The kind of capture (this, byref, bycopy), which must not be init-capture.
Implicit	Whether the capture was implicit or explicit.
Var	The local variable being captured, or null if capturing this.
EllipsisLoc	The location of the ellipsis (...) for a capture that is a pack expansion, or an invalid source location to indicate that this is not a pack expansion.
