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,
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,
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 false 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

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

ACE_INLINE bool ACE_InputCDR::do_byte_swap void   )  const
 

If true 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  )

ACE_CDR::Octet minor
 

Set the underlying GIOP version..

ACE_INLINE bool ACE_InputCDR::good_bit void   )  const
 

returns false if a problem has been detected.

int ACE_InputCDR::grow size_t  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_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.
