## 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.

ACE_InputCDR::ACE_InputCDR | ( | ACE_Data_Block * | data,

|  | 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 | rd_pos,

|  | 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_INLINE ACE_InputCDR::~ACE_InputCDR | ( | void |  | ) |

| Destructor.

|  | 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.
