                                  java.lang.Class<?>... interfaces)

Set the interfaces of the proxy class.
The interfaces must be public.

Parameters:

interfaces - The interfaces

Returns:

This builder

getMethodFilter

public java.util.function.Predicate<java.lang.reflect.Method> getMethodFilter()

Returns:

The current method filter

setMethodFilter

public ProxyBuilder setMethodFilter(@Nonnull
                                    java.util.function.Predicate<java.lang.reflect.Method> methodFilter)
