OperationDef

OperationDef::contexts
OperationDef::describe()
OperationDef::mode
OperationDef::result

Synopsis:

Interface OperationDef describes an IDL operation. It inherits from Contained. Note that the parameters and exceptions of the operation are not directly available as attributes but they are available through the inherited operation Contained::describe().

One use of OperationDef is to construct an NVList for a specific operation. See CORBA::ORB::create_operation_list() for details.

CORBA:

 // IDL 
 enum OperationMode { NORMAL, ONEWAY };
 
 interface OperationDef : Contained {
 	typedef Identifier ContextIdentifier;
 	typedef sequence <ContextIdentifier>
 		ContextIdSeq;
 	attribute TypeCode result;
 	attribute OperationDef::OperationMode mode;
 	attribute IdentifierSeq contexts;
 };

Notes:

CORBA defined.

OperationDef::contexts

Synopsis:

 attribute ContextIdentifierSeq contexts;

Description:

Gives the list of context identifiers specified in the context clause of the operation.

Notes:

CORBA defined.

OperationDef::describe()

Synopsis:

The operation describe() is inherited from Contained. It returns a structure of type Contained::Description:

 // IDL
 struct Description {
 	Identifier name;
 	any value
 };

The name member of this structure contains the string "OperationDescription".

The TypeCode of the value member is:

 _tc_OperationDescription

The value of the any is a structure of type:

 // IDL
 struct OperationDescription {
 	Identifier name;
 	RepositoryId id;
 	RepositoryId defined_in;
 	TypeCode result;
 	OperationDef::OperationMode mode;
 	sequence<OperationDef::ContextIdentifier>
 		contexts;
 	sequence<ParameterDescription>
 		parameters;
 	sequence<ExceptionDesciption> exceptions;
 };
