Enum Constant Summary

Enum Constants
Enum Constant and Description
`RDMA_CM_EVENT_ADDR_CHANGE` This event is generated when the network device associated with this ID through address resolution changes its hardware address.
`RDMA_CM_EVENT_ADDR_ERROR` This event is generated on the client (active) side.
`RDMA_CM_EVENT_ADDR_RESOLVED` This event is generated on the client (active) side in response to rdma_resolve_addr().
`RDMA_CM_EVENT_CONNECT_ERROR` This event may be generated on the active or passive side of the connection.
`RDMA_CM_EVENT_CONNECT_REQUEST` This is generated on the passive side of the connection to notify the user of a new connection request.
`RDMA_CM_EVENT_CONNECT_RESPONSE` This event may be generated on the active side of the connection to notify the user that the connection request has been successful.
`RDMA_CM_EVENT_DEVICE_REMOVAL` This event is generated when the RDMA CM indicates that the device associated with the rdma_cm_id has been removed.
`RDMA_CM_EVENT_DISCONNECTED` This event is generated on both sides of the connection in response to rdma_disconnect().
`RDMA_CM_EVENT_ESTABLISHED` This event is generated on both sides of a connection.
`RDMA_CM_EVENT_MULTICAST_ERROR` This event is generated when an error occurs while attempting to join a multicast group or on an existing multicast group if the group had already been joined.
`RDMA_CM_EVENT_MULTICAST_JOIN` This event is generated in response to rdma_join_multicast().
`RDMA_CM_EVENT_REJECTED` This event may be generated on the client (active) side and indicates that a connection request or response has been rejected by the remote device.
`RDMA_CM_EVENT_ROUTE_ERROR` This is generated on the passive side of the connection to notify the user of a new connection request.
`RDMA_CM_EVENT_ROUTE_RESOLVED` This event is generated on the client (active) side in response to rdma_resolve_route().
`RDMA_CM_EVENT_TIMEWAIT_EXIT` This event is generated when the QP associated with the connection has exited its timewait state and is now ready to be re-used.
`RDMA_CM_EVENT_UNREACHABLE` This event is generated on the active side of a connection.

- Enum Constant Detail
  - RDMA_CM_EVENT_ADDR_CHANGE
```
public static final ConnectionEvent.EventType RDMA_CM_EVENT_ADDR_CHANGE
```
    This event is generated when the network device associated with this ID through address resolution changes its hardware address. For example, this may happen following bonding fail over.
  - RDMA_CM_EVENT_ADDR_ERROR
```
public static final ConnectionEvent.EventType RDMA_CM_EVENT_ADDR_ERROR
```
    This event is generated on the client (active) side. It is generated in response to rdma_resolve_addr() in the case where an error occurs. This may happen, for example, if the device cannot be found such as when a user supplies an incorrect device
  - RDMA_CM_EVENT_ADDR_RESOLVED
```
public static final ConnectionEvent.EventType RDMA_CM_EVENT_ADDR_RESOLVED
```
    This event is generated on the client (active) side in response to rdma_resolve_addr(). It is generated when the system is able to resolve the server address supplied by the client.
  - RDMA_CM_EVENT_CONNECT_ERROR
```
public static final ConnectionEvent.EventType RDMA_CM_EVENT_CONNECT_ERROR
```
    This event may be generated on the active or passive side of the connection. It is generated when an error occurs while attempting to establish a connection.
  - RDMA_CM_EVENT_CONNECT_REQUEST
```
public static final ConnectionEvent.EventType RDMA_CM_EVENT_CONNECT_REQUEST
```
    This is generated on the passive side of the connection to notify the user of a new connection request. It indicates that a connection request has been received.
  - RDMA_CM_EVENT_CONNECT_RESPONSE
```
public static final ConnectionEvent.EventType RDMA_CM_EVENT_CONNECT_RESPONSE
```
    This event may be generated on the active side of the connection to notify the user that the connection request has been successful. The event is only generated on rdma_cm_ids which do not have a QP associated with them.
  - RDMA_CM_EVENT_DEVICE_REMOVAL
```
public static final ConnectionEvent.EventType RDMA_CM_EVENT_DEVICE_REMOVAL
```
    This event is generated when the RDMA CM indicates that the device associated with the rdma_cm_id has been removed.
  - RDMA_CM_EVENT_DISCONNECTED
```
public static final ConnectionEvent.EventType RDMA_CM_EVENT_DISCONNECTED
```
    This event is generated on both sides of the connection in response to rdma_disconnect(). The event will be generated to indicate that the connection between the local and remote devices has been disconnected.
  - RDMA_CM_EVENT_ESTABLISHED
```
public static final ConnectionEvent.EventType RDMA_CM_EVENT_ESTABLISHED
```
    This event is generated on both sides of a connection. It indicates that a connection has been established with the remote end point.
  - RDMA_CM_EVENT_MULTICAST_ERROR
```
public static final ConnectionEvent.EventType RDMA_CM_EVENT_MULTICAST_ERROR
```
    This event is generated when an error occurs while attempting to join a multicast group or on an existing multicast group if the group had already been joined. When this happens, the multicast group will no longer be accessible and must be rejoined if necessary.
  - RDMA_CM_EVENT_MULTICAST_JOIN
```
public static final ConnectionEvent.EventType RDMA_CM_EVENT_MULTICAST_JOIN
```
    This event is generated in response to rdma_join_multicast(). It indicates that the multicast join operation has completed successfully.
  - RDMA_CM_EVENT_REJECTED
```
public static final ConnectionEvent.EventType RDMA_CM_EVENT_REJECTED
```
    This event may be generated on the client (active) side and indicates that a connection request or response has been rejected by the remote device. This may happen for example if an attempt is made to connect with the remote end point on the wrong port.
  - RDMA_CM_EVENT_ROUTE_ERROR
```
public static final ConnectionEvent.EventType RDMA_CM_EVENT_ROUTE_ERROR
```
    This is generated on the passive side of the connection to notify the user of a new connection request. It indicates that a connection request has been received.
  - RDMA_CM_EVENT_ROUTE_RESOLVED
```
public static final ConnectionEvent.EventType RDMA_CM_EVENT_ROUTE_RESOLVED
```
    This event is generated on the client (active) side in response to rdma_resolve_route(). It is generated when the system is able to resolve the server address supplied by the client.
  - RDMA_CM_EVENT_TIMEWAIT_EXIT
```
public static final ConnectionEvent.EventType RDMA_CM_EVENT_TIMEWAIT_EXIT
```
    This event is generated when the QP associated with the connection has exited its timewait state and is now ready to be re-used. After a QP has been disconnected, it is maintained in a timewait state to allow any in flight packets to exit the network. After the timewait state has completed, the rdma_cm will report this event.
  - RDMA_CM_EVENT_UNREACHABLE
```
public static final ConnectionEvent.EventType RDMA_CM_EVENT_UNREACHABLE
```
    This event is generated on the active side of a connection. It indicates that the (remote) server is unreachable or unable to respond to a connection request.
- Method Detail
  - valueOf
```
public static ConnectionEvent.EventType 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
  - values
```
public static ConnectionEvent.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 (ConnectionEvent.EventType c : ConnectionEvent.EventType.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
