SAFS Init Files

There're many deployment files for configuration. We need to learn how SAFS read these depolyment files.

Let's use the IBT as the a small example for reading UseMultiThreadSearch parameter which determines if we use multi-thread algorithm for image comparing.

In the DefaultDriver.java, define a variable USE_MULTIPLE_THREADS to store client's choice about using multi-thread:

/**
 * Set true if image searches using BitTolerance 
 * should attempt to use parallel threading.
 * The current implementation of multi-threading is poor, 
 * and may actually be slower than NOT using multi-threading.
 * Current default is 'false'.
 * @see org.safs.image.SmallPieceComparator
 * @see org.safs.image.ScreenXYBTComparator  
 */
public static boolean USE_MULTIPLE_THREADS = false;

Then, in the DefaultDriver.java file, the initializeMiscConfigInfo() method will call configInfo's getNamedValue() method to read the configuration files. So in order to get client's choice of whether use multi-thread, we'll do:

String useMultiThread = configInfo.getNamedValue(DriverConstant.SECTION_SAFS_IBT, "UseMultiThreadSearch");
if(useMultiThread!=null) {
	ImageUtils.USE_MULTIPLE_THREADS = StringUtilities.convertBool(useMultiThread);
	Log.info("SAFS_IBT:UseMultiThreadSearch set to: "+ ImageUtils.USE_MULTIPLE_THREADS);
}

The corresponding test.ini file should be written like this:

[SAFS_IBT]
UseTwoDimensionMatch=true

Obviously the [SAFS_IBT]  is determined by parameter DriverConstant.SECTION_SAFS_IBT in configInfo.getNamedValue() method.

In org.safs.tools.drivers.DriverConstant.java, one constant DEFAULT_PROJECT_DATAPOOL is used to store test tables and app maps. Generally, all inputs except benchmarks are placed here.

Then, in org.safs.tools.drivers.AbstractDriver.java, in AbstractDriver class, the variable datapoolSource will use the DEFAULT_PROJECT_DATAPOOL as default value. In the method validateRootConfigureParameters() of AbstractDriver class, it will call:

datapoolSource = getProjectDirectoryInfo (configInfo.getNamedValue (
			                           DriverConstant.SECTION_SAFS_DIRECTORIES, "DataDir"),
			                           DriverConstant.DEFAULT_PROJECT_DATAPOOL);

for setting.

In jsafs.validateRootConfigureParameters() using datapoolSource = getProjectDirectoryInfo() get the directory of MAP files.
