Detailed Description

A CDR stream for reading, i.e. for demarshalling.

This class is based on the the CORBA spec for Java (98-02-29), java class omg.org.CORBA.portable.InputStream. It diverts in a few ways: + Operations to retrieve basic types take parameters by reference. + Operations taking arrays don't have offsets, because in C++ it is easier to describe an array starting from x+offset. + Operations return an error status, because exceptions are not widely available in C++ (yet). A particularly useful static member function for this buffer is an interpretive encoding routine, usable as a typecode interpreter callback. Ditto for decoding. These are used to support all OMG-IDL datatypes, even those not supported directly by put/get primitives.

Constructor & Destructor Documentation

TAO_InputCDR::TAO_InputCDR ( const char *  buf,
size_t  bufsiz,
int  byte_order = ACE_CDR_BYTE_ORDER,
ACE_CDR::Octet  major_version = TAO_DEF_GIOP_MAJOR,
ACE_CDR::Octet  minor_version = TAO_DEF_GIOP_MINOR,
TAO_ORB_Core orb_core = 0 
)

Create an input stream from an arbitrary buffer, care must be exercised wrt alignment, because this contructor will *not* work if the buffer is unproperly aligned.

TAO_InputCDR::TAO_InputCDR ( size_t  bufsiz,
int  byte_order = ACE_CDR_BYTE_ORDER,
ACE_CDR::Octet  major_version = TAO_DEF_GIOP_MAJOR,
ACE_CDR::Octet  minor_version = TAO_DEF_GIOP_MINOR,
TAO_ORB_Core orb_core = 0 
)

Create an empty input stream. The caller is responsible for putting the right data and providing the right alignment.

TAO_InputCDR::TAO_InputCDR ( const ACE_Message_Block data,
int  byte_order = ACE_CDR_BYTE_ORDER,
ACE_CDR::Octet  major_version = TAO_DEF_GIOP_MAJOR,
ACE_CDR::Octet  minor_version = TAO_DEF_GIOP_MINOR,
TAO_ORB_Core orb_core = 0 
)

Create an input stream from an ACE_Message_Block.

TAO_InputCDR::TAO_InputCDR ( const ACE_Message_Block data,
ACE_Lock lock,
int  byte_order = ACE_CDR_BYTE_ORDER,
ACE_CDR::Octet  major_version = TAO_DEF_GIOP_MAJOR,
ACE_CDR::Octet  minor_version = TAO_DEF_GIOP_MINOR,
TAO_ORB_Core orb_core = 0 
)

Create an input stream from an ACE_Message_Block with an optional lock used to protect the data.

TAO_InputCDR::TAO_InputCDR ( ACE_Data_Block data,
ACE_Message_Block::Message_Flags  flag = 0,
int  byte_order = ACE_CDR_BYTE_ORDER,
ACE_CDR::Octet  major_version = TAO_DEF_GIOP_MAJOR,
ACE_CDR::Octet  minor_version = TAO_DEF_GIOP_MINOR,
TAO_ORB_Core orb_core = 0 
)

Create an input stream from an ACE_Data_Block.

TAO_InputCDR::TAO_InputCDR ( ACE_Data_Block data,
ACE_Message_Block::Message_Flags  flag,
size_t  read_pointer_position,
size_t  write_pointer_position,
int  byte_order = ACE_CDR_BYTE_ORDER,
ACE_CDR::Octet  major_version = TAO_DEF_GIOP_MAJOR,
ACE_CDR::Octet  minor_version = TAO_DEF_GIOP_MINOR,
TAO_ORB_Core orb_core = 0 
)

Create an input stream from an ACE_Data_Block.

TAO_InputCDR::TAO_InputCDR ( const TAO_InputCDR rhs)

Make a copy of the current stream state, but does not copy the internal buffer; so the same stream can be read multiple times efficiently.

TAO_InputCDR::TAO_InputCDR ( const TAO_InputCDR rhs,
size_t  size,
ACE_CDR::Long  offset 
)

When interpreting indirected TypeCodes it is useful to make a "copy" of the stream starting in the new position.

TAO_InputCDR::TAO_InputCDR ( const TAO_InputCDR rhs,
size_t  size 
)

This creates an encapsulated stream, the first byte must be (per the spec) the byte order of the encapsulation. The default values for the allocators in this constructor are not 0, but are generated by the ORB. Refer to the constructor body in CDR.cpp for the code that supplies these values to the base class constructor.

TAO_InputCDR::TAO_InputCDR ( const TAO_OutputCDR rhs,
ACE_Allocator buffer_allocator = 0,
ACE_Allocator data_block_allocator = 0,
ACE_Allocator message_block_allocator = 0,
TAO_ORB_Core orb_core = 0 
)

Create an input CDR from an output CDR.

TAO_InputCDR::TAO_InputCDR ( ACE_InputCDR::Transfer_Contents  rhs,
TAO_ORB_Core orb_core = 0 
)

Initialize the contents of one CDR from another, without data copying and with minimimum locking overhead.

TAO_InputCDR::~TAO_InputCDR ( void  )

Destructor.

TAO_InputCDR::Codebase_URL_Map_Handle & TAO_InputCDR::get_codebase_url_map ( )
TAO_InputCDR::Repo_Id_Map_Handle & TAO_InputCDR::get_repo_id_map ( )

These methods are used by valuetype indirection support. Accessor to the indirect maps.

TAO_InputCDR::Value_Map_Handle & TAO_InputCDR::get_value_map ( )
TAO_ORB_Core * TAO_InputCDR::orb_core ( void  ) const

Accessor.

void TAO_InputCDR::reset_vt_indirect_maps ( )

If indirect map is not nil and not empty, unbind all entries. Called after demarshalling.

void TAO_InputCDR::set_codebase_url_map ( TAO_InputCDR::Codebase_URL_Map_Handle map)
void TAO_InputCDR::set_repo_id_map ( TAO_InputCDR::Repo_Id_Map_Handle map)

Updater of the maps. These updaters are used to make indirect maps in original stream take effect even during marshalling/demarshalling a redirected stream.

void TAO_InputCDR::set_value_map ( TAO_InputCDR::Value_Map_Handle map)
void TAO_InputCDR::throw_skel_exception ( int  error_num) [static]
