ThreadMode (EventBus 3.1.1 API)

java.lang.Object
- java.lang.Enum<ThreadMode>
- - org.greenrobot.eventbus.ThreadMode

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<ThreadMode>
```
public enum ThreadMode
extends java.lang.Enum<ThreadMode>
```
Each subscriber method has a thread mode, which determines in which thread the method is to be called by EventBus. EventBus takes care of threading independently from the posting thread.

Enum Constant Summary

Enum Constants
Enum Constant and Description
`ASYNC` Subscriber will be called in a separate thread.
`BACKGROUND` On Android, subscriber will be called in a background thread.
`MAIN` On Android, subscriber will be called in Android's main thread (UI thread).
`MAIN_ORDERED` On Android, subscriber will be called in Android's main thread (UI thread).
`POSTING` Subscriber will be called directly in the same thread, which is posting the event.

- Enum Constant Detail
  - POSTING
```
public static final ThreadMode POSTING
```
    Subscriber will be called directly in the same thread, which is posting the event. This is the default. Event delivery implies the least overhead because it avoids thread switching completely. Thus this is the recommended mode for simple tasks that are known to complete in a very short time without requiring the main thread. Event handlers using this mode must return quickly to avoid blocking the posting thread, which may be the main thread.
  - MAIN
```
public static final ThreadMode MAIN
```
    On Android, subscriber will be called in Android's main thread (UI thread). If the posting thread is the main thread, subscriber methods will be called directly, blocking the posting thread. Otherwise the event is queued for delivery (non-blocking). Subscribers using this mode must return quickly to avoid blocking the main thread. If not on Android, behaves the same as POSTING.
  - MAIN_ORDERED
```
public static final ThreadMode MAIN_ORDERED
```
    On Android, subscriber will be called in Android's main thread (UI thread). Different from MAIN, the event will always be queued for delivery. This ensures that the post call is non-blocking.
  - BACKGROUND
```
public static final ThreadMode BACKGROUND
```
    On Android, subscriber will be called in a background thread. If posting thread is not the main thread, subscriber methods will be called directly in the posting thread. If the posting thread is the main thread, EventBus uses a single background thread, that will deliver all its events sequentially. Subscribers using this mode should try to return quickly to avoid blocking the background thread. If not on Android, always uses a background thread.
  - ASYNC
```
public static final ThreadMode ASYNC
```
    Subscriber will be called in a separate thread. This is always independent from the posting thread and the main thread. Posting events never wait for subscriber methods using this mode. Subscriber methods should use this mode if their execution might take some time, e.g. for network access. Avoid triggering a large number of long running asynchronous subscriber methods at the same time to limit the number of concurrent threads. EventBus uses a thread pool to efficiently reuse threads from completed asynchronous subscriber notifications.

  - values
```
public static ThreadMode[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (ThreadMode c : ThreadMode.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static ThreadMode valueOf(java.lang.String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
