Enum Constant Summary

Enum Constants

Enum Constant	Description
CATCH_UP	Server should consume stream events to catch up to the offset contained in this response
COMMIT	Server should send back a SegmentCommitRequest after processing this response
COMMIT_CONTINUE	Never sent by the controller, but locally used by the controller during the segmentCommit() processing
COMMIT_SUCCESS	Commit succeeded, behave exactly like KEEP
DISCARD	Server should discard the rows in memory
FAILED	Commit failed.
HOLD	Server should send SegmentConsumedRequest after waiting for less than MAX_HOLD_TIME_MS
KEEP	Server should build a segment out of the rows in memory, and replace in-memory rows with the segment built
NOT_LEADER	Server should locate the current controller leader and re-send the message
NOT_SENT	Never sent by the controller, but locally used by server when sending a request fails
PROCESSED	Sent by controller as an acknowledgement to the SegmentStoppedConsuming message
UPLOAD_SUCCESS	Sent by controller as an acknowledgement during split commit for successful segment upload

Method Detail

values

public static SegmentCompletionProtocol.ControllerResponseStatus[] 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 (SegmentCompletionProtocol.ControllerResponseStatus c : SegmentCompletionProtocol.ControllerResponseStatus.values())
    System.out.println(c);

Returns:

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

valueOf

public static SegmentCompletionProtocol.ControllerResponseStatus 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
