Example 11 with Predicate

use of org.apache.camel.Predicate in project camel by apache.

the class BinaryExpression method createRegexExpression.

        @Override
        public <T> T evaluate(Exchange exchange, Class<T> type) {
            // reg ex should use String pattern, so we evaluate the right hand side as a String
            Predicate predicate = PredicateBuilder.regex(leftExp, rightExp.evaluate(exchange, String.class));
            if (operator == BinaryOperatorType.NOT_REGEX) {

Example 14 with Predicate

use of org.apache.camel.Predicate in project camel by apache.

the class WhenSkipSendToEndpointDefinition method createPredicate.

@Override
