Return a ResolvableType representing the generic parameter for the given indexes.

Usage

From source file:com.ocs.dynamo.utils.ClassUtils.java

/**
 * Return a Class<?> representing the generic parameter for the given indexes. Indexes are zero
 * based; for example given the type Map<Integer, List<String>>, getGeneric(0) will access the
 * Integer. Nested generics can be accessed by specifying multiple indexes; for example
 * getGeneric(1, 0) will access the String from the nested List. For convenience, if no indexes
 * are specified the first generic is returned.
 * //from w w  w  .ja v  a2 s  .  c om
 * @param type
 * @param fieldName
 * @param indexes
 * @return
 */
public static <T> Class<?> getResolvedType(Class<T> type, String fieldName, int... indexes) {
    Field field = getField(type, fieldName);
    if (field != null) {
        ResolvableType rt = ResolvableType.forField(field);
        if (rt != null) {
            if (indexes != null && indexes.length > 0) {
                rt = rt.getGeneric(indexes);
