Class InitialLdapContext

java.lang.Object
javax.naming.InitialContext
javax.naming.directory.InitialDirContext
javax.naming.ldap.InitialLdapContext
All Implemented Interfaces:
Context, DirContext, LdapContext
public class InitialLdapContext extends InitialDirContext implements LdapContext
This class is the starting context for performing LDAPv3-style extended operations and controls.

See javax.naming.InitialContext and javax.naming.InitialDirContext for details on synchronization, and the policy for how an initial context is created.

Request Controls

When you create an initial context (InitialLdapContext), you can specify a list of request controls. These controls will be used as the request controls for any implicit LDAP "bind" operation performed by the context or contexts derived from the context. These are called connection request controls. Use getConnectControls() to get a context's connection request controls.

The request controls supplied to the initial context constructor are not used as the context request controls for subsequent context operations such as searches and lookups. Context request controls are set and updated by using setRequestControls().

As shown, there can be two different sets of request controls associated with a context: connection request controls and context request controls. This is required for those applications needing to send critical controls that might not be applicable to both the context operation and any implicit LDAP "bind" operation. A typical user program would do the following: 

 InitialLdapContext lctx = new InitialLdapContext(env, critConnCtls);
 lctx.setRequestControls(critModCtls);
 lctx.modifyAttributes(name, mods);
 Controls[] respCtls =  lctx.getResponseControls();
It specifies first the critical controls for creating the initial context (critConnCtls), and then sets the context's request controls (critModCtls) for the context operation. If for some reason lctx needs to reconnect to the server, it will use critConnCtls. See the LdapContext interface for more discussion about request controls.

Service provider implementors should read the "Service Provider" section in the LdapContext class description for implementation details.
