Detailed Description

A CDR stream for writing, i.e. for marshalling.

This class is based on the the CORBA spec for Java (98-02-29), java class omg.org.CORBA.portable.OutputStream. It diverts in a few ways: + 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_OutputCDR::ACE_OutputCDR (  size_t    size = 0, int    byte_order = ACE_CDR_BYTE_ORDER, ACE_Allocator *    buffer_allocator = 0, ACE_Allocator *    data_block_allocator = 0, ACE_Allocator *    message_block_allocator = 0, size_t    memcpy_tradeoff = ACE_DEFAULT_CDR_MEMCPY_TRADEOFF, ACE_CDR::Octet    major_version = ACE_CDR_GIOP_MAJOR_VERSION, ACE_CDR::Octet    minor_version = ACE_CDR_GIOP_MINOR_VERSION )

Default constructor, allocates <size> bytes in the internal buffer, if <size> == 0 it allocates the default size.

ACE_OutputCDR::ACE_OutputCDR (  char *    data, size_t    size, int    byte_order = ACE_CDR_BYTE_ORDER, ACE_Allocator *    buffer_allocator = 0, ACE_Allocator *    data_block_allocator = 0, ACE_Allocator *    message_block_allocator = 0, size_t    memcpy_tradeoff = ACE_DEFAULT_CDR_MEMCPY_TRADEOFF, ACE_CDR::Octet    giop_major_version = ACE_CDR_GIOP_MAJOR_VERSION, ACE_CDR::Octet    giop_minor_version = ACE_CDR_GIOP_MINOR_VERSION )

Create an output stream from an arbitrary buffer, care must be exercised with alignment, because this contructor will align if needed. In this case <data> will not point to the start off the output stream. begin()->rd_prt() points to the start off the output stream. See ACE_ptr_align_binary() to properly align a pointer and use ACE_CDR::MAX_ALIGNMENT for the correct alignment.

ACE_OutputCDR::ACE_OutputCDR (  ACE_Message_Block *    data, int    byte_order = ACE_CDR_BYTE_ORDER, size_t    memcpy_tradeoff = ACE_DEFAULT_CDR_MEMCPY_TRADEOFF, ACE_CDR::Octet    giop_major_version = ACE_CDR_GIOP_MAJOR_VERSION, ACE_CDR::Octet    giop_minor_version = ACE_CDR_GIOP_MINOR_VERSION )

Build a CDR stream with an initial Message_Block chain, it will not* remove <data>, since it did not allocate it.

ACE_INLINE int ACE_OutputCDR::adjust (  size_t    size, char *&    buf )

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

write 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.

Member Data Documentation

ACE_Char_Codeset_Translator* ACE_OutputCDR::char_translator_ [protected]

If not nil, invoke for translation of character and string data.

ACE_Message_Block* ACE_OutputCDR::current_ [private]

The current block in the chain were we are writing.

size_t ACE_OutputCDR::current_alignment_ [private]

The current alignment as measured from the start of the buffer. Usually this coincides with the alignment of the buffer in memory, but, when we chain another buffer this "quasi invariant" is broken. The current_alignment is used to readjust the buffer following the stolen message block.

int ACE_OutputCDR::current_is_writable_ [private]

Is the current block writable. When we steal a buffer from the user and just chain it into the message block we are not supposed to write on it, even if it is past the start and end of the buffer.

int ACE_OutputCDR::do_byte_swap_ [private]

If not zero swap bytes at writing so the created CDR stream byte order does *not* match the machine byte order. The motivation for such a beast is that in some setting a few (fast) machines can be serving hundreds of slow machines with the opposite byte order, so it makes sense (as a load balancing device) to put the responsability in the writers. THIS IS NOT A STANDARD IN CORBA, USE AT YOUR OWN RISK

int ACE_OutputCDR::good_bit_ [private]

Set to 0 when an error ocurrs.

ACE_CDR::Octet ACE_OutputCDR::major_version_ [protected]

GIOP version information.

size_t ACE_OutputCDR::memcpy_tradeoff_ [private]

Break-even point for copying.

ACE_CDR::Octet ACE_OutputCDR::minor_version_ [protected]

ACE_Message_Block ACE_OutputCDR::start_ [private]

The start of the chain of message blocks.

int ACE_OutputCDR::wchar_maxbytes_ = sizeof (ACE_CDR::WChar) [static, protected]

Some wide char codesets may be defined with a maximum number of bytes that is smaller than the size of a wchar_t. This means that the CDR cannot simply memcpy a block of wchars to and from the stream, but must instead realign the bytes appropriately. In cases when wchar i/o is not allowed, such as with GIOP 1.0, or not having a native wchar codeset defined, the maxbytes is set to zero, indicating no wchar data is allowed.
