HandlerPriority (OpenHFT/Chronicle Core 2.27ea0 API)

java.lang.Object
- java.lang.Enum<HandlerPriority>
- - net.openhft.chronicle.core.threads.HandlerPriority

All Implemented Interfaces:

Serializable, Comparable<HandlerPriority>
```
public enum HandlerPriority
extends Enum<HandlerPriority>
```
Enum representing different priority levels for event handlers in an event loop. The priority determines how frequently and in what order the handlers are executed.

Enum Constant Summary

Enum Constants
Enum Constant and Description
`BLOCKING` Represents tasks that involve blocking operations.
`CONCURRENT` Represents tasks that can be performed concurrently, especially as they might block for some time.
`DAEMON` Represents tasks that are run only when there is nothing else to do.
`HIGH` Represents critical tasks that need to be run in a tight loop.
`MEDIUM` Represents less critical tasks.
`MONITOR` Represents tasks that are run periodically in a background thread.
`REPLICATION` Used for replication tasks to ensure that replication events run on a separate thread.
`REPLICATION_TIMER` Similar to TIMER, but specifically used for replication tasks.
`TIMER` Represents timing-based tasks which are called at regular intervals.

- Enum Constant Detail
  - HIGH
```
public static final HandlerPriority HIGH
```
    Represents critical tasks that need to be run in a tight loop. These tasks have the highest priority and are executed very frequently.
  - MEDIUM
```
public static final HandlerPriority MEDIUM
```
    Represents less critical tasks. These tasks are invoked approximately 1/4 as often as tasks with HIGH priority.
  - TIMER
```
public static final HandlerPriority TIMER
```
    Represents timing-based tasks which are called at regular intervals. These tasks are not sensitive to thread pauses such as garbage collection or debugging, making them more robust against delays compared to using absolute time differences.
  - DAEMON
```
public static final HandlerPriority DAEMON
```
    Represents tasks that are run only when there is nothing else to do. These tasks have a very low priority and are meant to be run in the background.
  - MONITOR
```
public static final HandlerPriority MONITOR
```
    Represents tasks that are run periodically in a background thread. These tasks are used for monitoring purposes.
  - BLOCKING
```
public static final HandlerPriority BLOCKING
```
    Represents tasks that involve blocking operations. These tasks are added to a cached thread pool to avoid blocking the main event loop.
  - REPLICATION
```
public static final HandlerPriority REPLICATION
```
    Used for replication tasks to ensure that replication events run on a separate thread. Alias for MEDIUM priority.
  - REPLICATION_TIMER
```
public static final HandlerPriority REPLICATION_TIMER
```
    Similar to TIMER, but specifically used for replication tasks. Alias for TIMER priority.
  - CONCURRENT
```
public static final HandlerPriority CONCURRENT
```
    Represents tasks that can be performed concurrently, especially as they might block for some time. Alias for MEDIUM priority.
- Method Detail
  - values
```
public static HandlerPriority[] 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 (HandlerPriority c : HandlerPriority.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static HandlerPriority valueOf(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:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - alias
```
public HandlerPriority alias()
```
    Returns the effective priority for the handler. Some priority levels are aliases for other priorities (e.g., REPLICATION is an alias for MEDIUM). This method returns the actual priority that should be used for scheduling.
    
    Returns:
    
    the effective HandlerPriority.
