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).

Constructor & Destructor Documentation

ACE_InputCDR::ACE_InputCDR ( const char * buf,

size_t bufsiz,

int byte_order = ACE_CDR_BYTE_ORDER,

ACE_CDR::Octet major_version = ACE_CDR_GIOP_MAJOR_VERSION,

ACE_CDR::Octet minor_version = ACE_CDR_GIOP_MINOR_VERSION

)

Create an input stream from an arbitrary buffer. The buffer must be properly aligned because this contructor will *not* work if the buffer is aligned unproperly.See ACE_ptr_align_binary() for instructions on how to align a pointer properly and use ACE_CDR::MAX_ALIGNMENT for the correct alignment.

ACE_InputCDR::ACE_InputCDR ( size_t bufsiz,

int byte_order = ACE_CDR_BYTE_ORDER,

ACE_CDR::Octet major_version = ACE_CDR_GIOP_MAJOR_VERSION,

ACE_CDR::Octet minor_version = ACE_CDR_GIOP_MINOR_VERSION

)

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

ACE_InputCDR::ACE_InputCDR ( const ACE_Message_Block * data,

int byte_order = ACE_CDR_BYTE_ORDER,

ACE_CDR::Octet major_version = ACE_CDR_GIOP_MAJOR_VERSION,

ACE_CDR::Octet minor_version = ACE_CDR_GIOP_MINOR_VERSION

)

Create an input stream from an ACE_Message_Block.
The alignment of the

data block is carried into the new ACE_InputCDR object. This constructor either increments the
data reference count, or copies the data (if it's a compound message block) so the caller can release the block immediately upon return.

ACE_InputCDR::ACE_InputCDR ( ACE_Data_Block * data,

ACE_Message_Block::Message_Flags flag = 0,

int byte_order = ACE_CDR_BYTE_ORDER,

ACE_CDR::Octet major_version = ACE_CDR_GIOP_MAJOR_VERSION,

ACE_CDR::Octet minor_version = ACE_CDR_GIOP_MINOR_VERSION

)

Create an input stream from an ACE_Data_Block. The <flag> indicates whether the <data> can be deleted by the CDR stream or not

ACE_InputCDR::ACE_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 = ACE_CDR_GIOP_MAJOR_VERSION,

ACE_CDR::Octet minor_version = ACE_CDR_GIOP_MINOR_VERSION

)

Create an input stream from an ACE_Data_Block. It also sets the read and write pointers at the desired positions. This would be helpful if the applications desires to create a new CDR stream from a semi-processed datablock.

ACE_InputCDR::ACE_InputCDR ( const ACE_InputCDR & rhs )

These make a copy of the current stream state, but do not copy the internal buffer, so the same stream can be read multiple times efficiently.

ACE_InputCDR::ACE_InputCDR ( const ACE_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.

ACE_InputCDR::ACE_InputCDR ( const ACE_InputCDR & rhs,

size_t size

)

This creates an encapsulated stream, the first byte must be (per the spec) the byte order of the encapsulation.

ACE_InputCDR::ACE_InputCDR ( const ACE_OutputCDR & rhs,

ACE_Allocator * buffer_allocator = 0,

ACE_Allocator * data_block_allocator = 0,

ACE_Allocator * message_block_allocator = 0

)

Create an input CDR from an output CDR.

ACE_InputCDR::ACE_InputCDR ( Transfer_Contents rhs )

Transfer the contents from <rhs> to a new CDR.

ACE_INLINE ACE_InputCDR::~ACE_InputCDR ( void )

Destructor.

Member Function Documentation

ACE_INLINE int ACE_InputCDR::adjust ( size_t size,

size_t align,

char *& buf

)

As above, but now the size and alignment requirements may be different.

ACE_INLINE int ACE_InputCDR::adjust ( size_t size,

char *& buf

)

Returns (in <buf>) the next position in the buffer aligned to <size>, it advances the Message_Block rd_ptr past the data (i.e., <buf> + <size>). Sets the good_bit to 0 and returns a -1 on failure.

ACE_INLINE int ACE_InputCDR::align_read_ptr ( size_t alignment )

Utility function to allow the user more flexibility. Skips up to the nearest <alignment>-byte boundary. Argument MUST be a power of 2. Returns 0 on success and -1 on failure.

ACE_INLINE int ACE_InputCDR::byte_order ( void ) const

If <do_byte_swap> returns 0, this returns ACE_CDR_BYTE_ORDER else it returns !ACE_CDR_BYTE_ORDER.

ACE_INLINE void ACE_InputCDR::char_translator ( ACE_Char_Codeset_Translator * )

Set the codeset translators.

ACE_INLINE ACE_Char_Codeset_Translator * ACE_InputCDR::char_translator ( void ) const

Access the codeset translators. They can be nil!

ACE_Data_Block * ACE_InputCDR::clone_from ( ACE_InputCDR & cdr )

Copy the data portion from the <cdr> to this cdr and return the data content (ie. the ACE_Data_Block) from this CDR to the caller. The caller is responsible for managing the memory of the returned ACE_Data_Block.

ACE_INLINE int ACE_InputCDR::do_byte_swap ( void ) const

If non-zero then this stream is writing in non-native byte order, this is only meaningful if ACE_ENABLE_SWAP_ON_WRITE is defined.

ACE_INLINE char * ACE_InputCDR::end ( void ) [private]

Points to the continuation field of the current message block.

void ACE_InputCDR::exchange_data_blocks ( ACE_InputCDR & cdr )

Exchange data blocks with the caller of this method. The read and write pointers are also exchanged. Note: We now do only with the start_ message block.

ACE_INLINE int ACE_InputCDR::get_version ( ACE_CDR::Octet & major,

ACE_CDR::Octet & minor

)

Set the underlying GIOP version..

ACE_INLINE int ACE_InputCDR::good_bit ( void ) const

returns zero if a problem has been detected.

int ACE_InputCDR::grow ( size_t newsize )

Grow the internal buffer, reset <rd_ptr> to the first byte in the new buffer that is properly aligned, and set <wr_ptr> to <rd_ptr> + newsize

ACE_INLINE size_t ACE_InputCDR::length ( void ) const

Return how many bytes are left in the stream.

ACE_InputCDR & ACE_InputCDR::operator= ( const ACE_InputCDR & rhs )

ACE_INLINE void ACE_InputCDR::rd_ptr ( size_t offset ) [private]

Move the rd_ptr ahead by <offset> bytes.

ACE_INLINE char * ACE_InputCDR::rd_ptr ( void )

Returns the current position for the rd_ptr....

ACE_CDR::Boolean ACE_InputCDR::read_array ( void * x,

size_t size,

size_t align,

ACE_CDR::ULong length

) [private]

Read an array of <length> elements, each of <size> bytes and the start aligned at a multiple of <align>. The elements are assumed to be packed with the right alignment restrictions. It is mostly designed for buffers of the basic types.
This operation uses <memcpy>; as explained above it is expected that using assignment is faster that <memcpy> for one element, but for several elements <memcpy> should be more efficient, it could be interesting to find the break even point and optimize for that case, but that would be too platform dependent.
