Instance Variables
Method summary
+ (void)
assignGloballyUniqueBytes: (unsigned char*)buffer;
Fills the supplied buffer with 12 bytes
that are unique to the subnet. The first two bytes
encode a sequence of the process. Then two bytes
encode the process ID followed by four bytes which
encode a time stamp. The last four bytes encode the
IP address. The caller must insure that the
buffer pointed to is large enough to hold
the twelve bytes.
- (BOOL)
isTemporary;
Description forthcoming.
Instance Variables for EOTemporaryGlobalID Class
@protected unsigned char _bytes;
Warning the underscore at the start of the
name of this instance variable indicates that, even
though it is not technically private, it is
intended for internal use within the package, and
you should not use the variable in other code.
@protected unsigned int _refCount;
Warning the underscore at the start of the
name of this instance variable indicates that, even
though it is not technically private, it is
intended for internal use within the package, and
you should not use the variable in other code.
NSString* EOGlobalIDChangedNotification;
This notification is intended to allow
EOTemporaryGlobalIDs to be replaced with
the corresponding EOKeyGlobalIDs. In theory one could
interpret this as a mechanism to allow primary key
attributes to be mutable class properties. Even
though EOF also posts this notification in that case,
it fails to consistently propagate the new value through
relationships. GDL2 may attempt to correct
that shortcoming in the future, but it may have serious
performance implications.
