Example 21 with StellarProcessor

use of org.apache.metron.stellar.common.StellarProcessor in project metron by apache.

public static void validate(String rule, Context context) {
    StellarProcessor processor = new StellarProcessor();
    Assert.assertTrue(rule + " not valid.", processor.validate(rule, context));
}

Example 22 with StellarProcessor

use of org.apache.metron.stellar.common.StellarProcessor in project metron by apache.

the class StellarProcessorUtils method run.

/**
 * This utility class is intended for use while unit testing Stellar operators.
 * It is included in the "main" code so third-party operators will not need
 * a test dependency on Stellar's test-jar.
 *
 * This class ensures the basic contract of a stellar expression is adhered to:
 * 1. Validate works on the expression
 * 2. The output can be serialized and deserialized properly
 *
 * @param rule
 * @param variables
 * @param context
 * @return ret
