Embodiment:
Be described further below in conjunction with the drawings and specific embodiments:
Set up the module general collection: functional module is divided into four basic modules: data are obtained, data processing, data presentation, data storage.And these four basic modules as the ground floor in the module relationship tree, carefully draw, promptly four basic modules are segmented from functional perspective.The inheritance that new module and the data that form are obtained, data processing, data presentation, four basic modules of data storage have stratiform.The definition of module can be expressed as formally: (Dom), wherein M is a module name to M=M for T, P, and T is the parent layer module name of module, and P is the attribute-name set of module, and Dom is the pairing codomain of attribute-name among the P; If the lower floor's property value among the P is 0, be referred to as element module MM (Meta-Module), if the lower floor's property value among the P is 1, be referred to as non-element module NMM (Non-Meta-Module).
Set up the global data district: the global data district is similar to the data bus in the architecture, and the exchanges data between responsible a plurality of modules is with shared.Simultaneously, also be the path that carries out streams data between the module.The global data district is that the DOUBLE type global variable of a variable length is used for realizing that the exchange of data is with shared.The global data district can be divided into exclusive district and shared region.Exclusive district is used for carrying out between two specific modules the exchange of data, promptly has only these two modules to have the right of reading and writing or read-write.Shared region is meant that the functional module of all selections all has the right of reading and writing or read-write.Originally the storage area that only distributes 256 DOUBLE sizes is expanded according to system resource when depositing large-scale array again.For large-scale exchanges data but system resource can't distribute more internal memories the time, handy disk file read in read mutual.
The foundation that concerns between the module: module relationship is a formed stratiform module relationship tree with set membership between several modules, the process of generation module relation rule collection is the process that generates with relation rule table between the layer module, forms module by all relation rule tables and closes rule set.
Concentrate sequential read to get next module from module, by searching the module relationship tree, find out between two modules and whether mate, as the result is empty, then search the parent layer module of one of them module and the matching relationship between another module, if still be empty, then search the matching relationship number of the same parent layer module separately of two modules, finally form IF condition 1 and condition 2 and ... and condition n THEN decision-making.
Generate negation element rule module collection: be selected in all given under Automatic Program generting machanism module collections, comprise all element modules and non-element module, add the superiors parent module of a virtual module M00 simultaneously as all modules.Revise that the lower floor's attribute in the P property set is 1 among the M00, establishing the module collection that all module collection are used to set up the module relationship derivation tree is D.
Generator rule module collection: selecting T attribute in all modules is the ground floor module collection D1 (M1i (i=0 that 0 module forms the module relationship tree, 1,2,3)), comprise several parent layer modules among the D1 and be 0 module, specify the relation between each module simultaneously, that is to say the mutual matching relationship between the ground floor module, matching relationship is stored in the node in the module relationship tree mutually.The T attribute of revising concentrated each module of ground floor module is M00; Form module collection D21 from module collection (D-D1) module that to select its T attribute be M10, select the module formation module collection D22 that the T attribute is M11 from module collection (D-D1-D21), the rest may be inferred, from module collection [D-D1-D21-...-D2 (i-1)] to select the T attribute be that the module of M1i forms module collection D2i; Each module collection D21, D22 ... D2i forms second layer module collection D2, and the module among the D2 is joined in the module relationship tree; And specify each module to concentrate relation in each module; Revise the D21 module and concentrate all module T attribute M10, revise the D22 module and concentrate all module T attribute M11 ... revise the D2i module and concentrate all module T attribute M1i; Specify the relation between the concentrated module of same module; While modified module collection D21, D22 ... lower floor's attribute among the parent module attribute collection P of D2i, if set is not empty, then lower floor's property value is 1, if set is empty, then lower floor's property value is 0; If set is not empty, specify the matching relationship of negation element intermodule in each set.
Algorithm above repeating, up to satisfy set (D-D1-D2-Dj) (j=1,2,3 ... n) be empty; Preserve the reasoning process of this module relationship tree in order to follow-up Automatic Program generting machanism.
New module adds fashionable: if its parent layer module is an element module, lower floor's attribute of then revising among the parent layer module P is 1, and revises the attribute of new module; If its parent layer module is non-element module, it may be noted that in adding module relationship tree process that then this module and its have the relation between the module of same parent layer module.Store this amended module relationship tree then, in order to reasoning process.
Carry out the reasoning of mating between the module: the process of utilizing the module relationship tree that generates to carry out module relationship match reasoning promptly is to judge the problem of whether mating between selected a plurality of functional module.Collect selected functional module, form the module collection, read first module in order, read module relational tree tree, the reasoning decision process is carried out in preparation, concentrates sequential read to get next module from module, finds out the matching relationship between the same parent layer module separately of these two modules, if the parent layer module is mated entirely, then this two module is mated entirely; If the parent layer module does not match fully, then this two module does not match fully; If the result who searches, then searches the matching relationship between another module of module of parent of one of them module for empty,, then search the matching relationship of the same parent layer module separately of two modules if lookup result still be a sky.Finally can form the judgment rule of " IF condition 1 and condition 2 and ... and condition n THEN decision-making ".
Virtual instrument software generates automatically: according to judging The reasoning results, if Conditions reports an error the relation of not matching between the specification module in false in reasoning process.If condition is true, then the data stream between the specification module can be compatible, and each module that can be dynamically connected certainly forms virtual instrument software, data stream is flowed between each module and flows out.Data flowing between each module.
By the reasoning to user-selected module, the data that draw between the user-selected module flow into and the compatibility that flows out, automatically determination data stream between each module inflow and the sequencing of outflow, generate virtual instrument software automatically.
Functional module is unified external interface.In each functional module, all comprise the interface of the functional module start and stop of standard.Automatically generate the operation that utilizes this standard interface to control all modules and stop.
