Example 36 with Predicate

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

the class LogicalExpression method createAndExpression.

private Expression createAndExpression(final Expression leftExp, final Expression rightExp) {
    return new Expression() {

        @Override
        public <T> T evaluate(Exchange exchange, Class<T> type) {
            Predicate predicate = ExpressionToPredicateAdapter.toPredicate(leftExp);
            predicate = PredicateBuilder.and(predicate, ExpressionToPredicateAdapter.toPredicate(rightExp));
            boolean answer = predicate.matches(exchange);
            return exchange.getContext().getTypeConverter().convertTo(type, answer);
        }

        @Override

}

Example 37 with Predicate

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

the class WhenSkipSendToEndpointDefinition method createPredicate.

@Override

    // the predicate and add the matches result as a property on the exchange
    final Predicate delegate = super.createPredicate(routeContext);
    return new Predicate() {

        @Override
        public boolean matches(Exchange exchange) {
            boolean matches = delegate.matches(exchange);

        }

        @Override
        public String toString() {
            return delegate.toString();
        }
    };
}
