Abstract
The present invention provides the formula designs and analytic method in a kind of application system, it include: the thought with object-oriented, take out an operation base class, define operation void method and parsing entrance, each specific arithmetic type: addition, subtraction, multiplication, division, constant, it is squared, obtain equipment variables value etc., be abstracted into an operation class, operation Similar integral is from operation base class, the characteristics of according to itself operation, realizes concrete operation method；Its recurrence is resolved into single object operation by the operational formula given for one, and the type of each object is operation base class type, and due to polymorphic characteristic, complicated operational formula is converted into the object operation of single type.According to the technical solution of the present invention, it can be very good complicated formula resolving into same type of object operation, for different application scenarios, by object oriented designing, can be very good to extend.
Description
Technical field
The present invention relates to software algorithm design fields, and in particular, to formula design and parsing in a kind of application system
Method.
Background technique
Have the operation that data are done with operation in many application system now, but in these existing systems for
The processing of formula there is no a kind of general processing scheme, can only all solve the problems, such as it is respective, code for recycling journey
Spend not high, the formula type of support is relatively simple, and is not easy to extend, operation that cannot well between support target.It is being
It unites in the use process in later period, some operations also need interim change, this, which wants the derivation of equation also, needs certain flexibility.
The system of Object-Oriented designs high cohesion, low coupling due to succession, encapsulation, polymorphic characteristic naturally
The system structure of conjunction, so that system is more flexible, is easier to extend.
Summary of the invention
The object of the present invention is to provide a kind of design of the operational formula of multiplexing that can be convenient and extension and parsing sides
Method.
The technical solution adopted by the present invention is that:
The thought of object-oriented is used in formula design and analytic method in a kind of application system, takes out an operation base
Class, define operation void method and parsing entrance, each specific arithmetic type: addition, subtraction, multiplication, division, often
Amount, squared, acquisition equipment variables value etc., are abstracted into an operation class, and operation Similar integral is transported from operation base class according to itself
The characteristics of calculation, realizes concrete operation method；Its recurrence is resolved into single object operation by the operational formula given for one,
The type of each object is operation base class type, and due to polymorphic characteristic, complicated operational formula is converted into unitary class
The object operation of type.
The arithmetic type include addition, subtraction, multiplication, division, constant, it is squared, obtain equipment variables value etc.,
In actual use, different operation classes can be taken out according to application scenarios and is extended.
There are two types of types for the operation class: operation is decomposable and operation is undecomposable.
The operation can decompose class attribute with multiple same types when instantiation, these attributes are exactly after decomposing
Single operand.
The parsing entrance is a static method, and concrete function is: according to specified operation distinguished symbol recognition sequence
Operational formula is resolved into multiple operations and creates corresponding operation example, keeps two principles: first identifying the low fortune of priority
It calculates；When decomposition formula, guarantee that bracket is pairs of appearance or does not occur on the left of the oeprator of identification.
The recurrence decomposes concrete implementation: judge whether the corresponding type of current operation example is decomposable class, it can
Decompose class calls parsing entrance function to create new operation example in the constructed fuction of instantiation, and so on, until solution
Analyse complete formula.
Technical solution of the present invention have the advantages that complicated formula is resolved into well it is same type of right
As operation；Extension can very easily be realized by object oriented designing for different application scenarios.
