Enum EventHandler.EventType

      extended by org.apache.hadoop.hbase.executor.EventHandler.EventType
All Implemented Interfaces:
Serializable, Comparable<EventHandler.EventType>
Enclosing class:
EventHandler

public static enum EventHandler.EventType
extends Enum<EventHandler.EventType>

List of all HBase event handler types. Event types are named by a convention: event type names specify the component from which the event originated and then where its destined -- e.g. RS2ZK_ prefix means the event came from a regionserver destined for zookeeper -- and then what the even is; e.g. REGION_OPENING.

We give the enums indices so we can add types later and keep them grouped together rather than have to add them always to the end as we would have to if we used raw enum ordinals.

Method Detail

values

public static EventHandler.EventType[] 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 (EventHandler.EventType c : EventHandler.EventType.values())
    System.out.println(c);

Returns:
an array containing the constants of this enum type, in the order they are declared

valueOf

public static EventHandler.EventType 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
