Example 41 with TypeConverter

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

the class BeanConverter method convertTo.

@FallbackConverter
public static Object convertTo(Class<?> type, Exchange exchange, Object value, TypeConverterRegistry registry) {
    // use a fallback type converter so we can convert the embedded body if the value is BeanInvocation
    if (BeanInvocation.class.isAssignableFrom(value.getClass())) {
        BeanInvocation bi = (BeanInvocation) value;
        if (bi.getArgs() == null || bi.getArgs().length != 1) {
            // not possible to convert at this time as we try to convert the data passed in at first argument
            return Void.TYPE;
        }
        Class<?> from = bi.getArgs()[0].getClass();
        Object body = bi.getArgs()[0];
        // maybe from is already the type we want
        if (type.isAssignableFrom(from)) {
            return body;
        }
        // no then try to lookup a type converter
        TypeConverter tc = registry.lookup(type, from);
        if (tc != null) {
            return tc.convertTo(type, exchange, body);
