Interface NamingContextDataStore

All Known Implementing Classes:
NamingContextImpl, TransientNamingContext

public interface NamingContextDataStore
This interface defines a set of methods that must be implemented by the "data store" associated with a NamingContext implementation. It allows for different implementations of naming contexts that support the same API but differ in storage mechanism.
  • Method Details

    • bindImpl

      void bindImpl(NameComponent n, Object obj, BindingType bt) throws SystemException
      Method which implements binding a name to an object as the specified binding type.
      Parameters:
      n - a NameComponent which is the name under which the object will be bound.
      obj - the object reference to be bound.
      bt - Type of binding (as object or as context).
      Throws:
      SystemException - One of a fixed set of CORBA system exceptions.
    • resolveImpl

      Method which implements resolving the specified name, returning the type of the binding and the bound object reference. If the id and kind of the NameComponent are both empty, the initial naming context (i.e., the local root) must be returned.
      Parameters:
      n - a NameComponent which is the name to be resolved.
      bth - the BindingType as an out parameter.
      Returns:
      the object reference bound under the supplied name.
      Throws:
      SystemException - One of a fixed set of CORBA system exceptions.
    • unbindImpl

      Object unbindImpl(NameComponent name) throws SystemException
      Method which implements unbinding a name.
      Parameters:
      name - name to unbind.
      Returns:
      the object reference bound to the name, or null if not found.
      Throws:
      SystemException - One of a fixed set of CORBA system exceptions.
    • listImpl

      void listImpl(int how_many, BindingListHolder bl, BindingIteratorHolder bi) throws SystemException
      Method which implements listing the contents of this NamingContext and return a binding list and a binding iterator.
      Parameters:
      how_many - The number of requested bindings in the BindingList.
      bl - The BindingList as an out parameter.
      bi - The BindingIterator as an out parameter.
      Throws:
      SystemException - One of a fixed set of CORBA system exceptions.
    • newContextImpl

      NamingContext newContextImpl() throws SystemException
      Method which implements creating a new NamingContext.
      Returns:
      an object reference for a new NamingContext object implemented by this Name Server.
      Throws:
      SystemException - One of a fixed set of CORBA system exceptions.
    • destroyImpl

      void destroyImpl() throws SystemException
      Method which implements destroying this NamingContext.
      Throws:
      SystemException - One of a fixed set of CORBA system exceptions.
    • isEmptyImpl

      boolean isEmptyImpl()
      Method which returns whether this NamingContext is empty or not.
      Returns:
      true if this NamingContext contains no bindings.
    • getNSPOA

      POA getNSPOA()
