Detailed Description

Implementation of a CDR encapsulation coder/decoder (Codec).

This coder/decoder (Codec) class encodes and decodes data to and from a CDR encapsulation, respectively. It is useful for creation of octet sequences that contain CDR encapsulations. Those octet sequences can then be placed in a IOP::ServiceContext or an IOP::TaggedComponent, for example.

Note:

This Codec should not be used for operations internal to the ORB core since it uses interpretive marshaling rather than compiled marshaling.

Constructor & Destructor Documentation

TAO_CDR_Encaps_Codec::TAO_CDR_Encaps_Codec (  CORBA::Octet    major, CORBA::Octet    minor, TAO_ORB_Core *    orb_core )

Constructor.

TAO_CDR_Encaps_Codec::~TAO_CDR_Encaps_Codec (  void    )  [protected]

Destructor. Only allow this class to be instantiated on the heap since it is reference counted.

TAO_CDR_Encaps_Codec::TAO_CDR_Encaps_Codec (  const TAO_CDR_Encaps_Codec &    )  [private]

Prevent copying through the copy constructor and the assignment operator.

Member Function Documentation

void TAO_CDR_Encaps_Codec::check_type_for_encoding (  const CORBA::Any &data    ACE_ENV_ARG_DECL )  [protected]

Typical reasons for failure include attempting to encode a type that isn't supported for the version of GIOP associated with this Codec.

CORBA::Any * TAO_CDR_Encaps_Codec::decode (  const CORBA::OctetSeq &data    ACE_ENV_ARG_DECL_WITH_DEFAULTS )  throw (CORBA::SystemException, IOP::Codec::FormatMismatch) [virtual]

Extract the TypeCode and the value from the octet sequence and place them into an Any. Implements IOP::Codec.

CORBA::Any * TAO_CDR_Encaps_Codec::decode_value (  const CORBA::OctetSeq &    data, CORBA::TypeCode_ptr tc    ACE_ENV_ARG_DECL_WITH_DEFAULTS )  throw (CORBA::SystemException, IOP::Codec::FormatMismatch, IOP::Codec::TypeMismatch) [virtual]

Extract the value from the octet sequence, based on the given TypeCode, and place it into an Any. Implements IOP::Codec.

CORBA::OctetSeq * TAO_CDR_Encaps_Codec::encode (  const CORBA::Any &data    ACE_ENV_ARG_DECL_WITH_DEFAULTS )  throw (CORBA::SystemException, IOP::Codec::InvalidTypeForEncoding) [virtual]

Encode the given data, including the TypeCode, into an octet sequence. Implements IOP::Codec.

CORBA::OctetSeq * TAO_CDR_Encaps_Codec::encode_value (  const CORBA::Any &data    ACE_ENV_ARG_DECL_WITH_DEFAULTS )  throw (CORBA::SystemException, IOP::Codec::InvalidTypeForEncoding) [virtual]

Encode the given data, excluding the TypeCode, into an octet sequence. Implements IOP::Codec.

void TAO_CDR_Encaps_Codec::operator= (  const TAO_CDR_Encaps_Codec &    )  [private]
