Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
Embodiment one
Fig. 1 is a kind of step flow chart of multi-mode matching method provided in an embodiment of the present invention.
Shown in referring to Fig.1, multi-mode matching method provided in this embodiment is applied to Ach-Corasick automatic machines, this is automatic Machine is a kind of algorithm in fact, i.e., specifically when this method be applied to run the electronic equipment of above-mentioned automatic machine.The multimode matching Method specifically includes step:
S101:It receives and needs matched character to be matched.
When needing to carry out matching operation to character, the character to be matched for receiving user or system input in advance is needed, with Just operation further is carried out to it.
S102:Matching operation will be carried out in character input to jump list to be matched.
After receiving character to be matched, using carrying out matching operation in the jump list produced previously according to failure tables, In the jump list include that prior exhaustive institute is stateful, and include that each state redirects state under each input character, By above-mentioned operation, to obtain the matching result of the character to be matched.
In the matching process, after inputting a character to be matched, in the end-state redirected by failure tables When determine, i.e., state transition is only related with current state and current input character, the state certainty after character to be matched is given It is limited and determines.It, can be straight according to current character to be matched when Aho-Corasick automatic machines are in free position It connects and finds NextState, therefore, when being matched by the jump list generated according to failure tables be just not required to retract, also just make The time complexity of character match is greatly lowered, and time complexity becomes O (M).
It can be seen from the above technical proposal that present embodiments providing a kind of multi-mode matching method, this method is applied to Ach-Corasick automatic machines specially receive and need matched character to be matched;By character input to be matched to previously according to Matching operation is carried out in the jump list that failure tables generate, obtains the matching result of character to be matched, jump list includes multiple shapes State further includes that each state redirects state under each input character.Since state transition is only in method provided by the present application Related with current state and current input character, after character to be matched is given state is necessarily limited and determination, therefore, into It is just not required to retract when row matching, to reduce the time complexity of character match, and then effectively increases matching efficiency.
Jump list in the present embodiment obtains as follows.
First, goto tables and failure tables are firstly generated.Wherein goto tables refer to AC automatic machines generate redirect list, It wherein include the list of jump procedure;Failure tables be then AC automatic machines redirected when it fails to match redirect list, Output tables are then the lists that matching result is exported according to matching operation.
Goto tables are to shift automatic machine by the state that all patterns in set of modes P are constituted, for given set P { p1, p2 ... pm }, the step of generating goto tables, are, for each pattern pi [1...j] (1 in P<=i<M+1), according to It includes letter sequentially input automatic machine from front to back, initial state D [0], if the current state D [p] of automatic machine, for Current letter pi [k] (1 in pi<=k<=j), without available transfer, then by total status number smax+1 of state machine, and will Current state inputs the transferring position after pi [k], D [p] [pi [k]]=smax is set to, if there is available transfer scheme D [p] [pi [k]]=q, then be transferred to state D [q], while taking out next letter pi [k+1] of pattern string, continues above Deterministic process.Here described in us without available transfer scheme, be equal to the original state D for being transferred to state machine D [0], i.e., there is D [p] [pi [k]]=0 for state of automata D [p], input character pi [k].
The generation of failure tables is the process of a breadth first search, in this process, passes through continuous ergodic state Trie trees obtain the failure tables.
On the basis of generating above-mentioned goto tables and failure tables, goto tables are merged and can be obtained with failure tables To above-mentioned jump list, wherein the step of all rollbacks are omitted, as shown in Fig. 2, wherein free position is omitted and jumps to 0 The arrow of state, such as in 4 states, 6 states are jumped to if inputting i, input e jumps to 5 states, inputs other characters then Jump directly to 0 state.
In the present embodiment in S102 steps, the specific steps of matching operation will be carried out in character input to jump list to be matched As described below:
First, lookup operation is carried out in jump list character input to be matched to above-mentioned steps obtained, to be transported Calculate result;
Then, output tables are generated.The generation of output tables is in fact much like with the end node mark in Trie trees, all It is the process modified to state at the end of pattern string, and output tables are then the sides in state node object with combination Formula embodies.
Then, the operation result of previous step is input in above-mentioned output tables and carries out lookup operation, to final Obtain the matching result that the pre- character to be matched is consistent.
It should be noted that for embodiment of the method, for simple description, therefore it is all expressed as a series of action group It closes, but those skilled in the art should understand that, the embodiment of the present invention is not limited by the described action sequence, because according to According to the embodiment of the present invention, certain steps can be performed in other orders or simultaneously.Secondly, those skilled in the art also should Know, embodiment described in this description belongs to preferred embodiment, and the involved action not necessarily present invention is implemented Necessary to example.
