It serves as // a testing tool to allow client developers to test their client // applications without having to have an instance provider available. // // Client developers that want to make use of this provider must register // this provider for their CIM classes. // // This provider uses the existing repository interface to store and // retrieve instances in a repository. A separate repository is created // to store the instances. The location of this new repository can be // specified in the environment variable PEGASUS_TEST_REPOSITORY. If // the environment variable is not set, the default location for the // new repository will be /tmp. // // The first time this provider is called to handle a request for a // particular CIM class, it creates the new repository if it does not // already exist. It then uses the repository interface to copy the // necessary objects (such as the namespace, the CIM class, superclasses // of the CIM class, and all the qualifiers) from the original repository // to the new repository. After the new repository is created, all // subsequent requests on the same CIM class will be processed using // the repository interface to access objects stored in the new repository. // #include <Pegasus/Common/Config.h> #include <Pegasus/Common/String.h> #include <Pegasus/Common/CIMInstance.h> #include <Pegasus/Common/OperationContext.h> #include <Pegasus/Common/CIMQualifierDecl.h> #include <Pegasus/Client/CIMClient.h> #include "DefaultInstanceProvider.h" PEGASUS_NAMESPACE_BEGIN DefaultInstanceProvider::DefaultInstanceProvider(void) { } DefaultInstanceProvider::~DefaultInstanceProvider(void) { } void DefaultInstanceProvider::initialize(CIMOMHandle & cimom) { // get the test repository path const char* testRepositoryPath = getenv("PEGASUS_TEST_REPOSITORY"); String repositoryDir; if (!testRepositoryPath) { // environment variable not set repositoryDir = "/tmp"; } else { repositoryDir = testRepositoryPath; } repositoryDir.append("/repository"); // create the repository object _repository = new CIMRepository(repositoryDir); } void DefaultInstanceProvider::terminate(void) { delete this; } /*************************************************************************** _copyClass ***************************************************************************/ void DefaultInstanceProvider::_copyClass( const String & nameSpace, const String & className) { CIMClient client; try { // connect to the CIM server as a client client.connectLocal(); } catch( Exception& ex ) { const String msg = "Connect failed.
