All Implemented Interfaces:

ComputeNodesI<CodeStoreType>

public class ComputeNodes<CodeStoreType extends ComputeCodeStore<?>>
extends Object
implements ComputeNodesI<CodeStoreType>

A ComputeNodes is a collection of ComputeNodes. Each node has a unique id corresponding to its order of creation.

Parameters:

numberOfNodes -

Method Detail

canAllocateNewComputeNode

public boolean canAllocateNewComputeNode()

Assume that it is easy to add more nodes...

Specified by:

canAllocateNewComputeNode in interface ComputeNodesI<CodeStoreType extends ComputeCodeStore<?>>

Returns:

if false, ComputeNodesI.newComputeNode() may throw any throwable.

getNthComputeNode

public ComputeNode<CodeStoreType> getNthComputeNode(int n)

Description copied from interface: ComputeNodesI

Get the nth element of the collection of compute nodes.

Specified by:

getNthComputeNode in interface ComputeNodesI<CodeStoreType extends ComputeCodeStore<?>>

isValidComputeNodeNumber

public boolean isValidComputeNodeNumber(int nodeNumber)

Description copied from interface: ComputeNodesI

Does a number correspond to a compute node?

Specified by:

isValidComputeNodeNumber in interface ComputeNodesI<CodeStoreType extends ComputeCodeStore<?>>

Parameters:

nodeNumber - number to check

Returns:

true if a valid compute node number, false otherwise.

newComputeNode

public int newComputeNode()

Description copied from interface: ComputeNodesI

Create a new compute node if compute nodes are dynamically creatable.

Specified by:

newComputeNode in interface ComputeNodesI<CodeStoreType extends ComputeCodeStore<?>>

Returns:

unique number for the new compute node, usable with #getComputeNode(int).

size

public int size()

Description copied from interface: ComputeNodesI

Return the (current) number of compute nodes.

Specified by:

size in interface ComputeNodesI<CodeStoreType extends ComputeCodeStore<?>>

Returns:

size of collection of compute nodes.
