Package com.couchbase.client.core.env

Class CoreEnvironment

java.lang.Object
com.couchbase.client.core.env.CoreEnvironment
public class CoreEnvironment
extends Object
The Environment is the main place in the SDK where configuration and state lives (i.e. I/O pools).

Note that unless you are using the core directly, you want to consider the child implementations for each language binding (i.e. the ClusterEnvironment for the java client).
