Method Details

resolveField

public static Field resolveField(Class<?> type,
 String name)

Resolves a Field for the given dot-separated field path, starting from the supplied root type and traversing the type hierarchy and container types as needed.

The resolution rules are:

• Each path segment is resolved using getDeclaredField while walking up the superclass hierarchy.
• If a resolved field is an array, traversal continues with its component type.
• If a resolved field is a Collection, traversal continues with the collection's generic element type.
• Only the last field in the path is returned.

Examples:

 resolveField(User.class, "name.first");
 resolveField(Order.class, "items.product.id");
 resolveField(Foo.class, "values"); // List<List<String>> resolves to List
 

This method performs structural type resolution only. It does not access or inspect runtime values.

Parameters:

type - the root class from which resolution starts

name - a dot-separated field path (e.g. "a.b.c")

Returns:

the Field corresponding to the last segment in the path

Throws:

QueryException - if any segment of the path cannot be resolved

UnsupportedOperationException - if an intermediate collection type does not expose resolvable generic information
