Field Detail

ZERO

public static final ConfigVersion ZERO

A synthetic version, older than anything the server could send.

(Actually, the server could send a version with a negative epoch to indicate the epoch is not yet initialized, but we want to ignore those undercooked configs.)

ConfigVersion

public ConfigVersion(long epoch,
                     long rev)

Parameters:

epoch - Major version. May be negative to indicate the epoch is not yet initialized. May be zero to indicate the server is too old to know about epochs.
