Method Summary

Modifier and Type	Method and Description
void	addLocalBias(Object key, int topologyId) Allow reading local data if the topology is still actual.
void	clear() The cache has been cleared and therefore all biases are forgotten.
List<Address>	getRemoteBias(Object key)
boolean	hasLocalBias(Object key) Check if we can read local data and update last-read timestamp for this key.
void	onTopologyChange(TopologyChangedEvent event)
void	renewRemoteBias(Object key, Address origin) Notify the component that the node is reading the biased entry and the bias should not be revoked unless necessary.
void	revokeLocalBias(Object key) Stop reading local data.
void	revokeLocalBiasForSegments(IntSet segments) Stop reading local data from this segment.
void	start()
BiasManager.Revocation	startRevokingRemoteBias(Object key, Address newBiased) Check if there are any nodes that have local bias, and starting replacing them with the provided address.

addLocalBias

public void addLocalBias(Object key,
                         int topologyId)

Description copied from interface: BiasManager

Allow reading local data if the topology is still actual.

Specified by:

addLocalBias in interface BiasManager

revokeLocalBias

public void revokeLocalBias(Object key)

Description copied from interface: BiasManager

Stop reading local data.

Specified by:

revokeLocalBias in interface BiasManager

revokeLocalBiasForSegments

public void revokeLocalBiasForSegments(IntSet segments)

Description copied from interface: BiasManager

Stop reading local data from this segment.

Specified by:

revokeLocalBiasForSegments in interface BiasManager

hasLocalBias

public boolean hasLocalBias(Object key)

Description copied from interface: BiasManager

Check if we can read local data and update last-read timestamp for this key.

Specified by:

hasLocalBias in interface BiasManager

Returns:

getRemoteBias

public List<Address> getRemoteBias(Object key)

Specified by:

getRemoteBias in interface BiasManager

startRevokingRemoteBias

public BiasManager.Revocation startRevokingRemoteBias(Object key,
                                                      Address newBiased)

Description copied from interface: BiasManager

Check if there are any nodes that have local bias, and starting replacing them with the provided address. The caller can find out the currently biased nodes from BiasManager.Revocation.biased() and is expected to send RevokeBiasCommand to the holders and when this completes call BiasManager.Revocation.complete() or BiasManager.Revocation.fail(). This method returns null when there is no need to revoke any bias on remote nodes. When BiasManager.Revocation.shouldRevoke() returns false, the caller should set up a handler through BiasManager.Revocation.handleCompose(Supplier) and retry calling this method in the handler.

Specified by:

startRevokingRemoteBias in interface BiasManager

Returns:

renewRemoteBias

public void renewRemoteBias(Object key,
                            Address origin)

Description copied from interface: BiasManager

Notify the component that the node is reading the biased entry and the bias should not be revoked unless necessary.

Specified by:

renewRemoteBias in interface BiasManager

clear

public void clear()

Description copied from interface: BiasManager

The cache has been cleared and therefore all biases are forgotten.

Specified by:

clear in interface BiasManager
