Define Documentation

#define CLASSIFIER_EXPORT   FEATURE_EXPORT

compiler specific flags to export functions and classes

#define EXPORT_CLASSIFIER (  classifier   )

Value: \ static classifier *clf; \ void INIT_EXPORT library_initialize() { clf = NULL; } \ void FINI_EXPORT library_finalize() { if (clf != NULL) delete clf; } \ \ extern "C" CLASSIFIER_EXPORT ClassifierAlgorithm* getClassifier(classifierparams &params) { if (clf == NULL) clf = new classifier(params); return clf; } Export a classifier This macro has to be used in global scope and gets substituted with the implementation for exporting a ClassifierAlgorithm singleton instance to the framework. Parameters: classifier  The Class that implements the ClassifierAlgorithm interface and should be exported to the framework.

Typedef Documentation

typedef parametermap classifierparams

Parameters passed to classifiers When initializing a classifier, an arbitrary number of named (string) parameters can be passed from the application (e.g. read from a config file). These key-value tuples can then be used by the classifier as configuration or initialization values. They are completely classifier specific. See also: Classifier ClassifierAlgorithm

typedef ClassifierAlgorithm*(* getClassifier_t)(const classifierparams &params)

Type of the getClassifier function This type definition is needed by the Classifier Wrapper to query a ClassifierAlgorithm implementation for an instance of its class.
