# corba_object

### MODULE

corba_object

### MODULE SUMMARY

The CORBA Object interface functions

### DESCRIPTION

This module contains the CORBA Object interface functions that can be called for all objects.

### EXPORTS

get_interface(Object) -> InterfaceDef

Types:

Object = #objref
InterfaceDef = term()

This function returns the full interface description for an object.

is_nil(Object) -> boolean()

Types:

Object = #objref

This function checks if the object reference has a nil object value, which denotes no object. It is the reference that is tested and no object implementation is involved in the test.

is_a(Object, Logical_type_id) -> Return
is_a(Object, Logical_type_id, Contexts) -> Return

Types:

Object = #objref
Logical_type_id = string()
Contexts = [Context]
Context = #'IOP_ServiceContext'{context_id = CtxId, context_data = CtxData}
CtxId = ?ORBER_GENERIC_CTX_ID
CtxData = {interface, Interface} | {userspecific, term()} | {configuration, Options}
Interface = string()
Options = [{Key, Value}]
Key = ssl_client_options
Value = allowed value associated with the given key
Return = boolean() | {'EXCEPTION', E}

The Logical_type_id is a string that is a share type identifier (repository id). The function returns true if the object is an instance of that type or an ancestor of the "most derived" type of that object.

The configuration context is used to override the global SSL client side configuration.

Note: Other ORB suppliers may not support this function completely according to the OMG specification. Thus, a is_a call may raise an exception or respond unpredictable if the Object is located on a remote node.

is_remote(Object) -> boolean()

Types:

Object = #objref

This function returns true if an object reference is remote otherwise false.

non_existent(Object) -> Return
non_existent(Object, Contexts) -> Return

Types:

Object = #objref
Contexts = [Context]
Context = #'IOP_ServiceContext'{context_id = CtxId, context_data = CtxData}
CtxId = ?ORBER_GENERIC_CTX_ID
CtxData = {interface, Interface} | {userspecific, term()} | {configuration, Options}
Interface = string()
Options = [{Key, Value}]
Key = ssl_client_options
Value = allowed value associated with the given key
Return = boolean() | {'EXCEPTION', E}

This function can be used to test if the object has been destroyed. It does this without invoking any application level code. The ORB returns true if it knows that the object is destroyed otherwise false.

The configuration context is used to override the global SSL client side configuration.

Note: The OMG have specified two different operators, _not_existent (CORBA version 2.0 and 2.2) and _non_existent (CORBA version 2.3), to be used for this function. It is not mandatory to support both versions. Thus, a non_existent call may raise an exception or respond unpredictable if the Object is located on a remote node. Depending on which version, ORB:s you intend to communicate with supports, you can either use this function or not_existent/1.

not_existent(Object) -> Return
not_existent(Object, Contexts) -> Return

Types:

Object = #objref
Contexts = [Context]
Context = #'IOP_ServiceContext'{context_id = CtxId, context_data = CtxData}
CtxId = ?ORBER_GENERIC_CTX_ID
CtxData = {interface, Interface} | {userspecific, term()} | {configuration, Options}
Interface = string()
Options = [{Key, Value}]
Key = ssl_client_options
Value = allowed value associated with the given key
Return = boolean() | {'EXCEPTION', E}

This function is implemented due to Interoperable purposes. Behaves as non_existent except the operator _not_existent is used when communicating with other ORB:s.

The configuration context is used to override the global SSL client side configuration.

is_equivalent(Object, OtherObject) -> boolean()

Types:

Object = #objref
OtherObject = #objref

This function is used to determine if two object references are equivalent so far the ORB easily can determine. It returns true if the target object reference is equal to the other object reference and false otherwise.

hash(Object, Maximum) -> int()

Types:

Object = #objref
Maximum = int()

This function returns a hash value based on the object reference that not will change during the lifetime of the object. The Maximum parameter denotes the upper bound of the value.
