Overview | The members read and write operations provide for the access and update of the list of elements of an OMG IDL structure definition in the Interface Repository. |
Original interface | StructDef Interface |
Exceptions | CORBA::SystemException |
Intended Usage
The members attribute contains a description of each structure member. The members read and write operation provide the means to access and update the members attribute.
Syntax
attribute StructMemberSeq members;
Read operations
The returned pointer references a sequence that is representative of the structure members. The memory is owned by the caller and can be released by invoking delete.
Write operations
The members parameter provides the list of structure members with which to update the StructDef.
Example
// C++ /// assume 'this_struct_def', 'pk_long_ptr', and 'pk_double_ptr' // have already been initialized CORBA::StructDef * this_struct_def; CORBA::PrimitiveDef * pk_long_ptr; CORBA::PrimitiveDef * pk_double_ptr; // establish and initialize the StructMemberSeq . . . CORBA::StructMemberSeq seq_update; seq_update.length (2); seq_update[0].name = CORBA::string_dup ("element_zero_long"); seq_update[0].type_def = CORBA::IDLType::_duplicate (pk_long_ptr); seq_update[1].name = CORBA::string_dup ("element_one_double"); seq_update[1].type_def = CORBA::IDLType::_duplicate (pk_double_ptr); // set the members attribute of the StructDef this_struct_def-> members (seq_update); // read the members attribute information from the StructDef CORBA::StructMemberSeq * returned_members; returned_members = this_struct_def-> members ();
