Method Details

onConnected

protected void onConnected()

Overrides:

onConnected in class Instruction

onDisconnected

protected void onDisconnected()

Overrides:

onDisconnected in class Instruction

getResultType

public AType getResultType()

Description copied from class: Instruction

Gets the stack type of the value produced by this Instruction.

Specified by:

getResultType in class Instruction

Returns:

The AType.

C> R accept(InsnVisitor<R,C> visitor,
 C ctx)

Description copied from class: Instruction

Pass this Instruction through the supplied InsnVisitor.

Specified by:

accept in class Instruction

Parameters:

visitor - The InsnVisitor.

ctx - The context.

Returns:

The return result from the InsnVisitor.

copy

public Branch copy()

Description copied from class: Instruction
