Using Caché Proxy Classes5.2.3 Generating Proxy Files ProgrammaticallyThe CacheConnection class includes the following three methods that can be used to generate proxyfiles from within a .NET program:CacheConnection.GenSourceFile()Generates a new CS or VB proxy file that may contain definitions for several classes.CacheConnection.GenSourceFile(filepath, generator, classlist, options, errors);Parameters:• filepath — A string containing the path and filename of the file to be generated.• generator — An ICodeGenerator object that generates either CS or VB code.• classlist — An IEnumerator iterator pointing to the list of classes that will be generated.• options — a GeneratorOptions object• errors — An IList array used to store any returned error messages.CacheConnection.GenMultipleSourceFiles()Generates a separate CS or VB proxy file named . for eachclass in classlist.CacheConnection.GenMultipleSourceFiles(dirpath, filetype, generator, classlist,options, errors);Parameters:• dirpath — A string containing the directory path for the files to be generated.• filetype — A string containing either ".vb" or ".cs", depending on the code to begenerated.• generator — An ICodeGenerator object that generates either CS or VB code.• classlist — An IEnumerator iterator pointing to the list of classes that will be generated.• options — A GeneratorOptions• errors — An IList array used to store any returned error messages.CacheConnection.GenAssembly()Generates an assembly file.32 Using the Caché Managed Provider for .NET
CacheConnection.GenAssembly(filepath, keyfile, classlist, options, errors);Parameters:• filepath — A string containing the path and filename of the file to be generated.• keyfile — A string containing the path and filename of an assembly keyfile (may benull if no keyfile is used).• classlist — An IEnumerator iterator pointing to the list of classes that will be generated.• options — An ICodeGenerator object.• errors — An IList array used to store any returned error messages.For a working example that uses all three methods, see the Proxy_8_MakeProxyFiles() method inthe bookdemos sample program (see The Caché .NET Sample Programs).5.2.3.1 Using the Proxy Generator MethodsThe following code fragments provide examples for defining the method parameters, and for callingeach of the three proxy generator methods.generator parameterThe generator can be either a CSharpCodeProvider or a VBCodeProvider.System.CodeDom.Compiler.ICodeGenerator generatorclasslist parameterEach of the three methods accepts an iterator pointing to the list of classes to be generated. Althoughonly two classes are listed in the following example, proxy classes for Sample.Address andSample.Employee are generated automatically because they are used by Sample.Person andSample.Company.ArrayList classes = new ArrayList();classes.Add("Sample.Company");classes.Add("Sample.Person");System.Collections.IEnumerator classlistclasslist = classes.GetEnumerator();options parameterGenerating Caché Proxy ClassesIn this example, no special namespace will be generated for the proxy code, a complete set of inheritedmethods will be generated for each class, and no extra code will be generated for use by mobileapplications.Using the Caché Managed Provider for .NET 33
