getGeneration()

public ByteString getGeneration()

generation indicates the freshness of the group information (including leader information) contained in this proto. Generations can be compared lexicographically; if generation A is greater than generation B, then the Group corresponding to A is newer than the Group corresponding to B, and should be used preferentially.

bytes generation = 4;

uint64 group_uid = 1;

Returns
Type	Description
`long`	The groupUid.

getLeaderIndex()

public int getLeaderIndex()

The last known leader tablet of the group as an index into tablets. May be negative if the group has no known leader.

getTablets(int index)

public Tablet getTablets(int index)

A list of tablets that are part of the group. Note that this list may not be exhaustive; it will only include tablets the server considers useful to the client. The returned list is ordered ascending by distance.

Tablet UIDs reference Tablet.tablet_uid.
