Class ConsistentNodeConfig<NodeIDType>

java.lang.Object

edu.umass.cs.reconfiguration.reconfigurationutils.ConsistentNodeConfig<NodeIDType>

Type Parameters:

NodeIDType -

All Implemented Interfaces:

NodeConfig<NodeIDType>, Stringifiable<NodeIDType>

Direct Known Subclasses:

ConsistentReconfigurableNodeConfig

public abstract class ConsistentNodeConfig<NodeIDType>
extends java.lang.Object
implements NodeConfig<NodeIDType>

This class isn't really used for anything other than as a parent for ConsistentReconfigurableNodeConfig, so it has been declared abstract (even though it has no abstract methods).

Constructor Detail

ConsistentNodeConfig

public ConsistentNodeConfig(NodeConfig<NodeIDType> nc)

Parameters:

nc -

Method Detail

getReplicatedServers

public java.util.Set<NodeIDType> getReplicatedServers(java.lang.String name)

Parameters:

name -

Returns:

Consecutive servers on the consistent hash ring to which this name hashes returned as an array.

nodeExists

public boolean nodeExists(NodeIDType id)

Specified by:

nodeExists in interface NodeConfig<NodeIDType>

Returns:

Whether the node id exists in the node config.

getNodeAddress

public java.net.InetAddress getNodeAddress(NodeIDType id)

Specified by:

getNodeAddress in interface NodeConfig<NodeIDType>

Returns:

InetAddress corresponding to id.

getBindAddress

public java.net.InetAddress getBindAddress(NodeIDType id)

Specified by:

getBindAddress in interface NodeConfig<NodeIDType>

Returns:

Locally bindable InetAddress corresponding to id.

getNodePort

public int getNodePort(NodeIDType id)

Specified by:

getNodePort in interface NodeConfig<NodeIDType>

Returns:

Port number corresponding to id.

getNodeSocketAddress

public java.net.InetSocketAddress getNodeSocketAddress(NodeIDType id)

Parameters:

id -

Returns:

Socket address corresponding to node id.

getNodeIDs

public java.util.Set<NodeIDType> getNodeIDs()

Specified by:

getNodeIDs in interface NodeConfig<NodeIDType>

Returns:

Set of all node IDs. Avoid using this method or at least avoid reusing the result of this method if the underlying set of nodes can change.

valueOf

public NodeIDType valueOf(java.lang.String strValue)

Description copied from interface: Stringifiable

Converts a string representation of a node id into the appropriate node id type. Put another way, this performs the reverse of the toString() method for things that are Stringifiable.

Specified by:

valueOf in interface Stringifiable<NodeIDType>

Returns:

Returns the object constructed from strValue.

getValuesFromStringSet

public java.util.Set<NodeIDType> getValuesFromStringSet(java.util.Set<java.lang.String> strNodes)

Description copied from interface: Stringifiable

Converts a set of string node ids using valueOf.

Specified by:

getValuesFromStringSet in interface Stringifiable<NodeIDType>

Returns:

Returns an ObjectType set constructed from a String set.

getValuesFromJSONArray

public java.util.Set<NodeIDType> getValuesFromJSONArray(org.json.JSONArray array)
                                                 throws org.json.JSONException

Specified by:

getValuesFromJSONArray in interface Stringifiable<NodeIDType>

Returns:

Returns an ObjectType set constructed from a JSONObject array.

Throws:

org.json.JSONException
