Detailed Description

A CDR stream for demarshalling CDR-encoded data.

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:


Constructor & Destructor Documentation

ACE_InputCDR::ACE_InputCDR ( const char *  buf,
size_t  bufsiz,
int  byte_order = ACE_CDR::BYTE_ORDER_NATIVE,
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_NATIVE,
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_NATIVE,
ACE_CDR::Octet  major_version = ACE_CDR_GIOP_MAJOR_VERSION,
ACE_CDR::Octet  minor_version = ACE_CDR_GIOP_MINOR_VERSION,
ACE_Lock lock = 0 
)

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_NATIVE,
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_NATIVE,
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 ( ACE_InputCDR::Transfer_Contents  x  ) 

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

ACE_InputCDR::~ACE_InputCDR ( void   )  [inline]

Destructor.


Member Function Documentation

int ACE_InputCDR::adjust ( size_t  size,
size_t  align,
char *&  buf 
) [inline]

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

int ACE_InputCDR::adjust ( size_t  size,
char *&  buf 
) [inline]

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 false and returns a -1 on failure.

int ACE_InputCDR::align_read_ptr ( size_t  alignment  )  [inline]

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.

int ACE_InputCDR::byte_order ( void   )  const [inline]

If do_byte_swap() returns false, this returns ACE_CDR_BYTE_ORDER else it returns !ACE_CDR_BYTE_ORDER.

void ACE_InputCDR::char_translator ( ACE_Char_Codeset_Translator ctran  )  [inline]

Set the codeset translators.

ACE_Char_Codeset_Translator * ACE_InputCDR::char_translator ( void   )  const [inline]

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.

Note:
The caller is responsible for managing the memory of the returned ACE_Data_Block.

bool ACE_InputCDR::do_byte_swap ( void   )  const [inline]

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

char * ACE_InputCDR::end ( void   )  [inline, 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.

void ACE_InputCDR::get_version ( ACE_CDR::Octet major,
ACE_CDR::Octet minor 
) [inline]

Set the underlying GIOP version..

bool ACE_InputCDR::good_bit ( void   )  const [inline]

returns false 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

size_t ACE_InputCDR::length ( void   )  const [inline]

Return how many bytes are left in the stream.

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

void ACE_InputCDR::rd_ptr ( size_t  offset  )  [inline, private]

Move the rd_ptr ahead by offset bytes.

char * ACE_InputCDR::rd_ptr ( void   )  [inline]

Returns the current position for the rd_ptr.

ACE_CDR::Boolean ACE_InputCDR::read_1 ( ACE_CDR::Octet x  )  [private]

ACE_CDR::Boolean ACE_InputCDR::read_16 ( ACE_CDR::LongDouble x  )  [private]

ACE_CDR::Boolean ACE_InputCDR::read_2 ( ACE_CDR::UShort x  )  [private]

ACE_CDR::Boolean ACE_InputCDR::read_4 ( ACE_CDR::ULong x  )  [private]

ACE_CDR::Boolean ACE_InputCDR::read_8 ( ACE_CDR::ULongLong x  )  [private]

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.
