public class InitialDirContext extends InitialContext implements DirContext {

    
Constructs an initial DirContext with the option of not initializing it. This may be used by a constructor in a subclass when the value of the environment parameter is not yet known at the time the InitialDirContext constructor is called. The subclass's constructor will call this constructor, compute the value of the environment, and then call init() before returning. 
Params:
  • lazy –  true means do not initialize the initial DirContext; false is equivalent to calling new InitialDirContext()
Throws:
