Catalogue is rebuild, Query Result recombinates query directory before returning, and returns to the inquiry mesh of the scope and condition that fall with query statement
Record paragraph can include non-qualified data, and the length after last calculation code data bit arithmetic is exactly two query directories pair
The quantity for the overlapping region answered, it is when the quantity of overlapping region is 0, then completely misaligned, when the quantity of overlapping region is not 0
When, then two coded datas have common factor.
It is described according to query statement real needs, with the time range screening preparation mark of query statement, finally accorded with
The Query Result of conjunction condition comprises the following steps that：The first bar and last bar of query directory during preparation is identified are in query statement
Removed in scope and condition；In preparation identifies, the length of each query directory coding is calculated, and it is corresponding to calculate query statement
Coding and the length after the overlapping computing of query directory coding；, will when length of the query directory code length more than overlapping computing
The query directory is cached, and the query directory of caching and the query directory returned are merged, and is returned as inquiry；Conversely, will
The query directory of return is verified, and obtains the query directory for meeting query statement.Looked into for printing equipment governor circuit state
It is big to ask the workload occurred in work, the present situation for wasting time and energy and easily malfunctioning, printing dress can be obtained moment using this method
Put governor circuit status data, this method do not recombinate sequence calculate, it is necessary to data context it is less, the computing resource of occupancy
Small, inquiry has reached the effect for reducing search space, to realize quick search.Operating efficiency will be effectively improved, and avoids grasping by mistake
The possibility of work, the recovery time being greatly saved after printer failure, facilitate printer operation and service work.
