Work with status characteristics

The IfxLoStat class stores some statistical information about a smart large object such as the size, last access time, last modified time, last status change, and so on. The following table shows the status information that you can obtain.

Table 1. Status information for a smart large object
Status information	Description
Last-access time	The time, in seconds, that the smart large object was last accessed This value is available only if the last-access time attribute is enabled for the smart large object. For more information, see Last-access time.
Last-change time	The time, in seconds, of the last change in status for the smart large object A change in status includes changes to metadata and user data (data updates and changes to the number of references). This system time is stored as number of seconds since January 1, 1970.
Last-modification time	The time, in seconds, that the smart large object was last modified A modification includes only changes to user data (data updates). This system time is stored as the number of seconds since January 1, 1970. On some platforms, the last-modification time might also have a microseconds component, which can be obtained separately from the seconds component.
Size	The size, in bytes, of the smart large object

To obtain a reference to the status structure, call the following method in the IfxSmartBlob class:

IfxLoStat IfxLoGetStat(int lofd)

To obtain particular categories of status information, call the methods shown in the following table.

Table 2. Methods for obtaining status information
Status information	Method signature in ifxLoStat class

Last-change time	int getLastStatusTime()
Last-modification time	int getLastModifyTimeM() - time in microseconds int getLastModifyTimeS() - time rounded to seconds
Size	int getSize()
