示例1: runTest
void FilenameTest::runTest(const char* filename, const char* fullFilename)
{
CPPUNIT_ASSERT(!fileExists(fullFilename));
DataCollector::FileCreationAttr attr;
DataCollector::initFileCreationAttr(attr);
attr.fileAccType = DataCollector::FAT_WRITE;
// write first dataset to file (create file)
dataCollector->open(filename, attr);
int data1 = rand();
dataCollector->write(1, ctInt, 1, Selection(Dimensions(1, 1, 1)), "data", &data1);
dataCollector->close();
// Now file must exist
CPPUNIT_ASSERT(fileExists(fullFilename));
// write second dataset to file (write to existing file of same name
dataCollector->open(filename, attr);
int data2 = rand();
dataCollector->write(2, ctInt, 1, Selection(Dimensions(1, 1, 1)), "data", &data2);
dataCollector->close();
// read data from file
attr.fileAccType = DataCollector::FAT_READ;
