NAME¶
corba_object - The CORBA Object interface functionsDESCRIPTION¶
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.
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.
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.
Types:
Object = #objref
This function returns true if an object reference is remote otherwise
false.
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.
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.
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.
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.
