Method Detail

clone

public DefaultCluster<ClusterType> clone()

Description copied from class: AbstractCloneableSerializable

This makes public the clone method on the Object class and removes the exception that it throws. Its default behavior is to automatically create a clone of the exact type of object that the clone is called on and to copy all primitives but to keep all references, which means it is a shallow copy. Extensions of this class may want to override this method (but call super.clone() to implement a "smart copy". That is, to target the most common use case for creating a copy of the object. Because of the default behavior being a shallow copy, extending classes only need to handle fields that need to have a deeper copy (or those that need to be reset). Some of the methods in ObjectUtil may be helpful in implementing a custom clone method. Note: The contract of this method is that you must use super.clone() as the basis for your implementation.

Specified by:

clone in interface CloneableSerializable

Overrides:

clone in class AbstractCloneableSerializable

Returns:

A clone of this object.

getIndex

public int getIndex()

Gets the cluster index.

Returns:

The index of the cluster.

getMembers

public java.util.ArrayList<ClusterType> getMembers()

Gets the members of the cluster.

Specified by:

getMembers in interface Cluster<ClusterType>

Returns:

The members of the cluster.

setIndex

public void setIndex(int index)

Sets the index of the cluster.

Parameters:

index - The new index.
