Example 1 with Stellar

use of org.apache.metron.stellar.dsl.Stellar in project metron by apache.

the class BaseFunctionResolver method resolveFunction.

/**
 * Resolves a Stellar function from a given class.
 * @param clazz The class.
 */
public static StellarFunctionInfo resolveFunction(Class<? extends StellarFunction> clazz) {
    StellarFunctionInfo info = null;
    // the class must be annotated
    if (clazz.isAnnotationPresent(Stellar.class)) {
        Stellar annotation = clazz.getAnnotation(Stellar.class);
        String fullyQualifiedName = getNameFromAnnotation(annotation);
        StellarFunction function = createFunction(clazz);
        if (fullyQualifiedName != null && function != null) {
            info = new StellarFunctionInfo(annotation.description(), fullyQualifiedName, annotation.params(), annotation.returns(), function);
        }
    }
    return info;
}

Example 2 with Stellar
