Method Detail

refreshBufferedClusterInfoData

public void refreshBufferedClusterInfoData()

Description copied from interface: ClusterInfoManager

Refreshes the cluster info caches.

Specified by:

refreshBufferedClusterInfoData in interface ClusterInfoManager

createInitialStateIfMissing

public void createInitialStateIfMissing()

BE CAREFUL when calling outside the BambooContainer context. This method for a primary node will always recreate the file with its initial state. This may lead to the cluster corruption.

Specified by:

createInitialStateIfMissing in interface ClusterInfoManager

getClusterInfoData

@NotNull
public @NotNull Optional<ClusterInfoData> getClusterInfoData()

Specified by:

getClusterInfoData in interface ClusterInfoManager

Returns:

gets the current ClusterInfoData if present, empty otherwise

getBufferedClusterInfoData

@NotNull
public @NotNull Optional<ClusterInfoData> getBufferedClusterInfoData()

Specified by:

getBufferedClusterInfoData in interface ClusterInfoManager

Returns:

gets the eventually consistent ClusterInfoData if present, empty otherwise

setLifecycle

public boolean setLifecycle(@NotNull
                            @NotNull NodeLifecycleState nodeLifecycleState)

Description copied from interface: ClusterInfoManager

Sets the NodeLifecycleState coming from the current node. Based on implementation, the node lifecycle states might be internally mapped to different cluster states or not affect the cluster state at all.

Specified by:

setLifecycle in interface ClusterInfoManager

Parameters:

nodeLifecycleState - new lifecycle state originating from node

Returns:

true if the state was changed, false otherwise
