JavaTM 2 Platform Std. Ed. v1.4.2
org.omg.IOP
Class TaggedComponentHolder
java.lang.Object
org.omg.IOP.TaggedComponentHolder
- All Implemented Interfaces:
- Streamable
- public final class TaggedComponentHolder
- extends Object
- implements Streamable
TaggedComponents contained in
TAG_INTERNET_IOP and
TAG_MULTIPLE_COMPONENTS profiles are identified by
unique numeric tags using a namespace distinct form that is used for
profile tags. Component tags are assigned by the OMG.
Specifications of components must include the following information:
- Component ID: The compound tag that is obtained
from OMG.
- Structure and encoding: The syntax of the component
data and the encoding rules. If the component value is
encoded as a CDR encapsulation, the IDL type that is
encapsulated and the GIOP version which is used for encoding
the value, if different than GIOP 1.0, must be specified as
part of the component definition.
- Semantics: How the component data is intended to be
used.
- Protocols: The protocol for which the component is
defined, and whether it is intended that the component be
usable by other protocols.
- At most once: whether more than one instance of this
component can be included in a profile.
Specification of protocols must describe how the components affect
the protocol. The following should be specified in any protocol
definition for each TaggedComponent that the protocol uses:
- Mandatory presence: Whether inclusion of the component
in profiles supporting the protocol is required (MANDATORY
PRESENCE) or not required (OPTIONAL PRESENCE).
- Droppable: For optional presence component, whether
component, if present, must be retained or may be dropped.
