It is recorded according to software module, and by the log recording of same module or multiple modules among identical file.However, in software
Debugging process in, the output quantity of daily record is often quite huge and is not easy to read.In order to which check on entire program executes step
Suddenly, it needs to open multiple journal files comparisons to check, can just check on.Not only heavy workload, but also easily malfunction, one is small
The heart will miss the detail of track problems, and log analysis is very difficult.In addition, the debugging log of function rank is due to information
It measures huge, can also computer performance be caused to decline, and common directly performance can be caused to decline into line function character match.
In order to solve problem above, the present invention proposes a kind of software debugging daily record output control method, to realize
The control of function daily record exports, and help is provided to the positioning of site problems.
Hash table（Hash table）Also hash table is cried, is according to key value（Key value）And it directly accesses
Data structure.That is, it is recorded by the way that key value is mapped to a position in table to access, to accelerate lookup
Speed.This mapping function is called hash function, and the array for storing record is called hash table.
Hash function can make the access process to a data sequence more rapid effective, pass through hash function, data element
Element will be positioned quickly.
The common method of Hash method includes following several：
（1）Direct addressing：It is hash address to take some of keyword or keyword linear function values.That is H (key)=key
Or H (key)=akey b, wherein a and b are constant（This hash function is called itself function）.If wherein H (key）In
Through there is value, just looked for toward next, until H (key）Middle void value, just puts in.
（2）Digital analysis method：One group of data, such as the birthdate of one group of employee are analyzed, at this moment we have found that birth
Former bit digitals of date are substantially the same, and in this case, the probability to conflict occur will be very big, but it have been found that the date
Latter several indicate that the digital difference at month and exact date is very big, if constituting hash address with subsequent number, rush
Prominent probability can be substantially reduced.Therefore digital analysis method is exactly the rule for finding out number, is constructed as far as possible using these data
Conflict the lower hash address of probability.
（3）Middle square method：The centre several after keyword square is taken to be used as hash address.
（4）Jackknife method：It is divided into the identical several parts of digit, last part digit can be different keyword, then
Take this several part superposition and（Remove carry）As hash address.Numerical digit superposition can have displacement superposition and boundary to be superimposed two kinds
Method.Displacement superposition is the lowest order alignment of each section after dividing, and is then added；Boundary superposition is from one end to another
End folds back and forth along segmentation circle, and then alignment is added.
（5）Random number method：A random function is selected, takes the random value of keyword as hash address, commonly used in key
The different occasion of word length.
（6）Leaving remainder method：It is scattered to take keyword to remove the remainder of rear gained by some number p no more than the long m of hash table table
Column address.That is H (key)=key MOD p, p=m.Not only can be to the direct modulus of keyword, it also can be in folding, square taking
Modulus after equal operations.It is critically important to the selection of p, prime number or m are generally taken, if p choosings is bad, easy tos produce synonym.
