Method Detail

getSocketAddress

public InetSocketAddress getSocketAddress()

Description copied from interface: ReplicationNode

The socket address used by other nodes in the replication group to communicate with this node.

Specified by:

getSocketAddress in interface ReplicationNode

Returns:

the socket address

isQuorumAck

public boolean isQuorumAck()

Returns whether the node was acknowledged by a quorum and its entry is therefore considered durable. Secondary nodes are always considered acknowledged.

isRemoved

public boolean isRemoved()

setChangeVersion

public void setChangeVersion(int changeVersion)

getChangeVersion

public int getChangeVersion()

getNameIdPair

public NameIdPair getNameIdPair()

getName

public String getName()

Description copied from interface: ReplicationNode

Returns the unique name associated with the node.

Specified by:

getName in interface ReplicationNode

Returns:

the name of the node

getNodeId

public int getNodeId()

getType

public NodeType getType()

Description copied from interface: ReplicationNode

Returns the type associated with the node.

Specified by:

getType in interface ReplicationNode

Returns:

the node type

getHostName

public String getHostName()

Description copied from interface: ReplicationNode

Returns the host name associated with the node.

Specified by:

getHostName in interface ReplicationNode

Returns:

the host name of the node

setHostName

public void setHostName(String hostName)

getPort

public int getPort()

Description copied from interface: ReplicationNode

Returns the port number associated with the node.

Specified by:

getPort in interface ReplicationNode

Returns:

the port number of the node

setPort

public void setPort(int port)

getHostPortPair

public String getHostPortPair()

getBarrierState

public CleanerBarrierState getBarrierState()

setBarrierState

public CleanerBarrierState setBarrierState(CleanerBarrierState barrierState)

setQuorumAck

public void setQuorumAck(boolean quorumAck)

setRemoved

public void setRemoved(boolean isRemoved)

getJEVersion

public JEVersion getJEVersion()

Returns the JE Version most recently noted running on this node, or null if not known.

updateJEVersion

public void updateJEVersion(JEVersion otherJEVersion)

Updates the JE version most recently known running on this node to match the version specified. Does nothing if the argument is null.

Parameters:

otherJEVersion - the version or null

toString

public String toString()

Overrides:

toString in class Object

equivalent

public boolean equivalent(RepNodeImpl mi)

Checks if the argument represents the same node, ignoring fields that might legitimately vary over time. Like the equals method, considers all fields, except ignores the quorumAck field (which may change temporarily), the nodeId (since it may not have been resolved as yet), and the isRemoved, barrierState, changeVersion, and jeVersion fields (which can change over time).

Parameters:

mi - the other object in the comparison

Returns:

true if the two are equivalent

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
