/**
* A collection of built-in priority constants for the JAX-RS components that are supposed to be
* ordered based on their {@code javax.annotation.Priority} class-level annotation value when used
* or applied by JAX-RS runtime.
*
* For example, JAX-RS filters and interceptors are grouped in chains for each of the message
* processing extension points: Pre, PreMatch, Post as well as ReadFrom and WriteTo.
* Each of these chains is sorted based on priorities which are represented as integer numbers.
* All chains, except Post, are sorted in ascending order; the lower the number the higher the priority.
* The Post filter chain is sorted in descending order to ensure that response filters are executed in
* reverse order.
*
*
* JAX-RS components that belong to the same priority class (same integer value) are executed in an
* implementation-defined manner. By default, when the {@code @Priority} annotation is absent on a component,
* for which a priority should be applied, the {@link Priorities#USER} priority value is used.
