Interface State

All Superinterfaces:

UsesCustomNull

All Known Implementing Classes:

BleDeviceState, BleManagerState, BleServerState

public interface State
extends UsesCustomNull

Bitwise enum contract for representing the state of devices and managers. Implementations are BleDeviceState and BleManagerState. Not intended for subclassing outside this library but go wild if you want.

Nested Class Summary

Modifier and Type	Interface and Description
static class	State.ChangeEvent<T_State extends State> Abstract base class for DeviceStateListener.StateEvent and ManagerStateListener.StateEvent.
static class	State.ChangeIntent Enumerates the intention behind a state change - as comprehensively as possible, whether the application user intended for the state change to happen or not.

Method Summary

Modifier and Type	Method and Description
boolean	didEnter(int oldStateBits, int newStateBits) Given an old and new state mask, for example from DeviceStateListener.onEvent(com.idevicesinc.sweetblue.DeviceStateListener.StateEvent) or ManagerStateListener.onEvent(com.idevicesinc.sweetblue.ManagerStateListener.StateEvent), this method tells you whether the the 'this' state was appended.
boolean	didExit(int oldStateBits, int newStateBits) Reverse of didEnter(int, int).
boolean	isNull() Returns true if this state is meant to stand in for Java's built-in null.
