This class implements a value-semantic Guid type.
Declared in <bdlb_guid.h>
class Guid;Each object represents an unconstrained Guid object, but its uniqueness is not guaranteed, and this component provides no ability to generate a GUID.
This class provides a constructor and several accessors with names and parameters phrased using RFC 4122 field names. These names are used (by RFC 4122 and this component) as designators for parts of the GUID even when those names do not accurately describe the parts (for example, time low names bytes 0-3 of the GUID regardless of whether the values of those bytes come from a clock or are generated randomly).
| Name | Description |

Unnamed enum | GUID layout constants. |

Guid [constructor] | Constructors |
operator= | Assignment operators |
begin | Return a pointer to the first byte of this GUID. |
clockSeqHi | Return the 5-bit value of the clk_seq_hi_res field of this guid as specified in RFC 4122, excluding the variant bits. |
clockSeqHiRes | Return the 8-bit clk_seq_hi_res field of this guid as specified in RFC 4122. |
clockSeqLow | Return the 8-bit clk_seq_low field of this guid as specified in RFC 4122. |
data | Return a pointer offering unmodifiable access to the most significant byte of this guid object. |
end | Return a pointer one past the end of the least significant byte of this guid object. |
format | Write the value of this object to the specified output buffer. |
node | Return the 48-bit node field of this guid as specified in RFC 4122. |
operator[] | Return the byte at the specified offset in this guid. |
print | Write the value of this object to the specified output stream. |
timeHi | Return the 12-bit value of the time_hi_and_version field of this guid as specified in RFC 4122, excluding the version bits. |
timeHiAndVersion | Return the 16-bit time_hi_and_version field of this guid as specified in RFC 4122. |

timeMid | Return the 16-bit time_mid field of this guid as specified in RFC 4122. |
variant | Return the 3-bit variant portion of the clk_seq_hi_res field of this guid as specified in RFC 4122. |
version | Return the four-bit version portion of the time_hi_and_version field of this guid as specified in RFC 4122. |
