configured attributes for this member.

getAttribute

String getAttribute(String key)

Returns the value of the specified key for this member or null if value is undefined.

Parameters:

key - The key to lookup.

Returns:

The value for this member key.

setAttribute

void setAttribute(String key,
                  String value)

Defines a key-value pair string attribute for this member available to other cluster members.

Parameters:

key - The key for this property.

value - The value that corresponds to this attribute and this member.

removeAttribute

void removeAttribute(String key)

Parameters:

key - The key to be deleted from the member attributes

Since:

3.2

getVersion

MemberVersion getVersion()

Returns the Hazelcast codebase version of this member; this may or may not be different from the version reported by Cluster.getClusterVersion(), for example when a node with a different codebase version is added to an existing cluster.
