int	getMachineId() Return the Member's machine Id.
String	getMachineName() Determine the configured name for the Machine (such as a host name) in which this Member resides.
String	getMemberName() Determine the configured name for the Member.
int	getPort() Return the port of the Member's DatagramSocket for point-to-point communication.
String	getProcessName() Determine the configured name for the Process (such as a JVM) in which this Member resides.
String	getRackName() Determine the configured name for the Rack (such as a physical rack, cage or blade frame) in which this Member resides.
String	getRoleName() Determine the configured role name for the Member.
String	getSiteName() Determine the configured name for the Site (such as a data center) in which this Member resides.
long	getTimestamp() Return the date/time value (in cluster time) that the Member joined.
UID	getUid() Return the unique identifier of the Member.

Method Detail

getAddress

InetAddress getAddress()

Return the IP address of the Member's DatagramSocket for point-to-point communication.

Returns:

the IP address of the Member's DatagramSocket

getPort

int getPort()

Return the port of the Member's DatagramSocket for point-to-point communication.

Returns:

the port of the Member's DatagramSocket

getMachineId

int getMachineId()

Return the Member's machine Id.

This identifier should be the same for Members that are on the same physical machine, and different for Members that are on different physical machines.

Returns:

the Member's machine Id

getTimestamp

long getTimestamp()

Return the date/time value (in cluster time) that the Member joined.

Returns:

the cluster date/time value that the Member joined

getUid

UID getUid()

Return the unique identifier of the Member.

Returns:

the unique identifier of the Member

getId

int getId()

Return a small number that uniquely identifies the Member at this point in time and does not change for the life of this Member.

This value sometimes referred to as a "mini-id" in comparison to the "Uid" returned by getUid(). It does not uniquely identify the Member throughout the duration of the cluster because Members that existed but left the cluster before this Member existed may have had the same mini-id value and the same goes for Members that may join the cluster after this Member leaves the cluster.

Returns:

the mini-id of the Member

getSiteName

String getSiteName()

Determine the configured name for the Site (such as a data center) in which this Member resides. This name is used for logging purposes and to differentiate among multiple geographic sites.

Returns:

the configured Site name or null

Since:

Coherence 3.2

getRackName

String getRackName()

Determine the configured name for the Rack (such as a physical rack, cage or blade frame) in which this Member resides. This name is used for logging purposes and to differentiate among multiple racks within a particular data center, for example.

Returns:

the configured Rack name or null

Since:

Coherence 3.2

getMachineName

String getMachineName()

Determine the configured name for the Machine (such as a host name) in which this Member resides. This name is used for logging purposes and to differentiate among multiple servers, and may be used as the basis for determining the MachineId property.

Returns:

the configured Machine name or null

Since:

Coherence 3.2

getProcessName

String getProcessName()

Determine the configured name for the Process (such as a JVM) in which this Member resides. This name is used for logging purposes and to differentiate among multiple processes on a a single machine.

Returns:

the configured Process name or null

Since:

Coherence 3.2

getMemberName

String getMemberName()

Determine the configured name for the Member. This name is used for logging purposes and to differentiate among Members running within a particular process.

Returns:

the configured Member name or null

Since:

Coherence 3.2

getRoleName

String getRoleName()

Determine the configured role name for the Member. This role is completely definable by the application, and can be used to determine what Members to use for specific purposes, such as to send particular types of work to.

Returns:

the configured role name for the Member or null
