public class: InitialLdapContext [javadoc | source]
java.lang.Object
   javax.naming.InitialContext
      javax.naming.directory.InitialDirContext
         javax.naming.ldap.InitialLdapContext

All Implemented Interfaces:
    LdapContext, DirContext, Context

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.

Fields inherited from javax.naming.InitialContext:
myProps,  defaultInitCtx,  gotDefault
Constructor:
 public InitialLdapContext() throws NamingException 
    Constructs an initial context using no environment properties or connection request controls. Equivalent to new InitialLdapContext(null, null).
    Throws:
    NamingException - if a naming exception is encountered
 public InitialLdapContext(Hashtable<?, ?> environment,
    Control[] connCtls) throws NamingException 
    Constructs an initial context using environment properties and connection request controls. See javax.naming.InitialContext for a discussion of environment properties.

    This constructor will not modify its parameters or save references to them, but may save a clone or copy. Caller should not modify mutable keys and values in environment after it has been passed to the constructor.

    connCtls is used as the underlying context instance's connection request controls. See the class description for details.

    Parameters:
    environment - environment used to create the initial DirContext. Null indicates an empty environment.
    connCtls - connection request controls for the initial context. If null, no connection request controls are used.
    Throws:
    NamingException - if a naming exception is encountered
