Class Interceptor.Priority

Priorities that define the order in which interceptors are invoked. These values should be used with the Priority annotation.

• Interceptors defined by platform specifications should have priority values in the range PLATFORM_BEFORE up until LIBRARY_BEFORE, or starting at PLATFORM_AFTER.
• Interceptors defined by extension libraries should have priority values in the range LIBRARY_BEFORE up until APPLICATION, or LIBRARY_AFTER up until PLATFORM_AFTER.
• Interceptors defined by applications should have priority values in the range APPLICATION up until LIBRARY_AFTER.

An interceptor that must be invoked before or after another defined interceptor can choose any appropriate value.

Interceptors with smaller priority values are called first. If more than one interceptor has the same priority, the relative order of these interceptor is undefined.

For example, an extension library might define an interceptor like this:

 @Priority(Interceptor.Priority.LIBRARY_BEFORE+10)
 @Interceptor
 public class ValidationInterceptor { ... }
