Class AttachedState

java.lang.Object

org.multibit.hd.hardware.core.fsm.AbstractHardwareWalletState

org.multibit.hd.hardware.core.fsm.AttachedState

All Implemented Interfaces:

HardwareWalletState

public class AttachedState
extends AbstractHardwareWalletState

State to provide the following to hardware wallet clients:

• State transitions based on low level message events

The "attached" state represents when the underlying hardware has detected a new device that matches the required parameters.

This could be a USB attachment or a server socket accepting a connection.

The next state is normally Connected or Detached

Since:

0.0.1

Method Detail

await

public void await(HardwareWalletContext context)

Description copied from interface: HardwareWalletState

Invoke the state's awaiting behaviour. This may cause an immediate state transition (such as from Attached to Connected) or it may start a background process to wait for an event.

Specified by:

await in interface HardwareWalletState

Overrides:

await in class AbstractHardwareWalletState

Parameters:

context - The current context providing parameters for decisions

internalTransition

protected void internalTransition(HardwareWalletClient client,
                                  HardwareWalletContext context,
                                  MessageEvent event)

Description copied from class: AbstractHardwareWalletState

Initiate a move to the next state through the given client.

Typically the client is used to move in to or out of a "waiting state" and the context is updated with new data

Specified by:

internalTransition in class AbstractHardwareWalletState

Parameters:

client - The hardware wallet client for sending messages

context - The current context providing parameters for decisions

event - The event driving the transition
