package org.jboss.weld.context;

/**
 * 
 * Lifecycle management for built in contexts. {@link ManagedContext} only allows a context to be activated, deactivated and
 * destroyed. It does not allow the context to be associated with an underlying data store. These operations are defined on
 * {@link BoundContext}.
 * 
 *
 * 
 * Weld provides a number of managed contexts: {@link SessionContext}, {@link ConversationContext}, {@link RequestContext}. All
 * these managed contexts are scoped to the thread, and propagation of the backing store between threads is the responsibility
 * of the managed context user.
