Enum Constant Detail

JOINED

public static final GridDiscoveryEventType JOINED

New node has been discovered and joined grid topology. Note that even though a node has been discovered there could be a number of warnings in the log. In certain situations GridGain doesn't prevent a node from joining but prints warning messages into the log.

LEFT

public static final GridDiscoveryEventType LEFT

Node has normally left the grid.

FAILED

public static final GridDiscoveryEventType FAILED

GridGain detected that node has presumably crashed and is considered failed.

METRICS_UPDATED

public static final GridDiscoveryEventType METRICS_UPDATED

Callback for when node's metrics are updated. In most cases this callback is invoked with every heartbeat received from a node (including local node).

Method Detail

values

public static final GridDiscoveryEventType[] values()

Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:

for(GridDiscoveryEventType c : GridDiscoveryEventType.values())
        System.out.println(c);

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

valueOf

public static GridDiscoveryEventType 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.)

Throws:: IllegalArgumentException - if this enum type has no constant with the specified name
Parameters:: name - the name of the enum constant to be returned.
Returns:: the enum constant with the specified name
