Class CouchbaseConfig

java.lang.Object

net.spy.memcached.compat.SpyObject

com.couchbase.client.vbucket.config.CouchbaseConfig

All Implemented Interfaces:

Config

public class CouchbaseConfig
extends net.spy.memcached.compat.SpyObject
implements Config

A Config implementation that represents a "couchbase" bucket config. This Config implementation is VBucket-aware and allows several operations against a list of nodes and VBuckets. For "memcached" type buckets, see the MemcacheConfig implementation.

Method Detail

getReplicasCount

public int getReplicasCount()

Specified by:

getReplicasCount in interface Config

getVbucketsCount

public int getVbucketsCount()

Specified by:

getVbucketsCount in interface Config

getServersCount

public int getServersCount()

Specified by:

getServersCount in interface Config

getServer

public java.lang.String getServer(int serverIndex)

Specified by:

getServer in interface Config

getVbucketByKey

public int getVbucketByKey(java.lang.String key)

Specified by:

getVbucketByKey in interface Config

getMaster

public int getMaster(int vbucketIndex)

Specified by:

getMaster in interface Config

getReplica

public int getReplica(int vbucketIndex,
                      int replicaIndex)

Specified by:

getReplica in interface Config

getCouchServers

public java.util.List<java.net.URL> getCouchServers()

Specified by:

getCouchServers in interface Config

foundIncorrectMaster

public int foundIncorrectMaster(int vbucket,
                                int wrongServer)

Specified by:

foundIncorrectMaster in interface Config

getServers

public java.util.List<java.lang.String> getServers()

Specified by:

getServers in interface Config

getVbuckets

public java.util.List<VBucket> getVbuckets()

Specified by:

getVbuckets in interface Config

compareTo

public ConfigDifference compareTo(Config config)

Compares the given configuration with the current configuration and calculates the differences. Note that if a MEMCACHE type config is used, only the servers are compared because MEMCACHE buckets do not contain vBuckets. If COUCHBASE configs are compared, also the vBucket changes are taken into account.

Specified by:

compareTo in interface Config

Parameters:

config - the new config to compare against.

Returns:

the differences between the configurations.

getHashAlgorithm

public net.spy.memcached.HashAlgorithm getHashAlgorithm()

Specified by:

getHashAlgorithm in interface Config

getRestEndpoints

public java.util.List<java.lang.String> getRestEndpoints()

Specified by:

getRestEndpoints in interface Config

nodeHasActiveVBuckets

public boolean nodeHasActiveVBuckets(java.net.InetSocketAddress node)

Check if the given node has active VBuckets. Note that the passed in node needs to have the port stripped off, so it can be checked independent of ports.

Parameters:

node - the node to verify.

Returns:

if it has active VBuckets or not.

getConfigType

public ConfigType getConfigType()

Specified by:

getConfigType in interface Config

isTainted

public boolean isTainted()

Description copied from interface: Config

If the current config is tainted and will most possibly be replaced soon with a clean one.

Specified by:

isTainted in interface Config

Returns:

true if it is tainted, false otherwise.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
