DESCRIPTION

Manages a Naming Service for a remote name space which includes bindings for net_local naming context. All strings are stored in wide character format. A Name Binding consists of a name (that's the key), a value string and an optional type string (no wide chars).

Initialization and termination methods.

ACE_Remote_Name_Space (void);

"Do-nothing" constructor.

ACE_Remote_Name_Space (const ASYS_TCHAR *hostname, u_short port);

Specifies the scope of this namespace, opens and memory-maps the associated file (if accessible) or contacts the dedicated name server process for NET_LOCAL namespace.

int open (const ASYS_TCHAR *servername, u_short port);

Specifies the scope of this namespace, opens and memory-maps the associated file (if accessible) or contacts the dedicated name server process for NET_LOCAL namespace.

~ACE_Remote_Name_Space (void);

destructor, do some cleanup :TBD: last dtor should "compress" file

virtual int bind (
    const ACE_WString &name_in,
    const ACE_WString &value_in,
    const char *type_in = ""
    );

Bind a new name to a naming context (Wide character strings).

virtual int rebind (
    const ACE_WString &name_in,
    const ACE_WString &value_in,
    const char *type_in = ""
    );

Overwrite the value or type of an existing name in a ACE_Remote_Name_Space or bind a new name to the context, if it didn't exist yet. (Wide charcter strings interface).

virtual int unbind (const ACE_WString &name_in);

Delete a name from a ACE_Remote_Name_Space (Wide charcter strings Interface).

virtual int resolve (
    const ACE_WString &name_in,
    ACE_WString &value_out,
    char *&type_out
    );

Get value and type of a given name binding (Wide chars). The caller is responsible for deleting both value_out and type_out!

virtual int list_names (
    ACE_WSTRING_SET &set_out,
    const ACE_WString &pattern_in
    );

Get a set of names matching a specified pattern (wchars). Matching means the names must begin with the pattern string.

virtual int list_values (
    ACE_WSTRING_SET &set_out,
    const ACE_WString &pattern_in
    );

Get a set of values matching a specified pattern (wchars). Matching means the values must begin with the pattern string.

virtual int list_types (
    ACE_WSTRING_SET &set_out,
    const ACE_WString &pattern_in
    );

Get a set of types matching a specified pattern (wchars). Matching means the types must begin with the pattern string.

virtual int list_name_entries (
    ACE_BINDING_SET &set,
    const ACE_WString &pattern
    );

Get a set of names matching a specified pattern (wchars). Matching means the names must begin with the pattern string. Returns the complete binding associated each pattern match.

virtual int list_value_entries (
    ACE_BINDING_SET &set,
    const ACE_WString &pattern
    );

Get a set of values matching a specified pattern (wchars). Matching means the values must begin with the pattern string. Returns the complete binding associated each pattern match.

virtual int list_type_entries (
    ACE_BINDING_SET &set,
    const ACE_WString &pattern
    );

Get a set of types matching a specified pattern (wchars). Matching means the types must begin with the pattern string. Returns the complete binding associated each pattern match.

virtual void dump (void) const;

Dump the state of the object.
