Constructor & Destructor Documentation

Move() [1/3]

TTAProgram::Move::Move	(	Terminal *	src,
		Terminal *	dst,
		const TTAMachine::Bus &	bus,
		MoveGuard *	guard

Creates a guarded move.

The ownership of the source and destination terminal objects and the guard will be passed to the move.

Parameters

src	The source of the move.
dst	The destination of the move.
bus	The bus on which the transport is carried.
guard	The Boolean expression the move is predicated with.

copy()

std::shared_ptr< Move > TTAProgram::Move::copy

(

const

Makes a copy of the move.

The copy is identical, except that it is not registered to the instruction of the original move (and therefore, any address it refers to is not meaningful).

Returns

A copy of the move.
