@Deprecated
public class ReflectionHelper
extends java.lang.Object

Some reflection helper code. This is in FML's coremod land. It's split in two because the two classes need to exist in separate classloaders. Modders shouldn't be using this class anyways. Use ObfuscationReflectionHelper when dealing with obfuscated fields or methods.

Deprecated.

Finds a field with the specified name in the given class and makes it accessible. Note: for performance, store the returned value and avoid calling this repeatedly.

Throws an exception if the field is not found.

Parameters:

clazz - The class to find the field on.

fieldName - The name of the field to find (used in developer environments, i.e. "maxStackSize").

fieldObfName - The obfuscated name of the field to find (used in obfuscated environments, i.e. "field_77777_bU"). If the name you are looking for is on a class that is never obfuscated, this should be null.

Returns:

The field with the specified name in the given class.
