All Implemented Interfaces:

```
public class AnnotationAwareOrderComparator
extends OrderComparator
```
AnnotationAwareOrderComparator is an extension of OrderComparator that supports Spring's Ordered interface as well as the @Order and @Priority annotations, with an order value provided by an Ordered instance overriding a statically defined annotation value (if any).
Consult the Javadoc for OrderComparator for details on the sort semantics for non-ordered objects.

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`protected Integer`	`findOrder(Object obj)`	This implementation checks for `@Order` or `@Priority` on various kinds of elements, in addition to the `Ordered` check in the superclass.
`Integer`	`getPriority(Object obj)`	This implementation retrieves an @`Priority` value, allowing for additional semantics over the regular @`Order` annotation: typically, selecting one object over another in case of multiple matches but only one object to be returned.
`static void`	`sort(Object[] array)`	Sort the given array with a default AnnotationAwareOrderComparator.
`static void`	`sort(List<?> list)`	Sort the given list with a default `AnnotationAwareOrderComparator`.
`static void`	`sortIfNecessary(Object value)`	Sort the given array or List with a default AnnotationAwareOrderComparator, if necessary.

```
@Nullable
protected Integer findOrder(Object obj)
```
    This implementation checks for @Order or @Priority on various kinds of elements, in addition to the Ordered check in the superclass.
    Overrides:
    findOrder in class OrderComparator
    Parameters:
    obj - the object to check
    Returns:
    the order value, or null if none found
  - getPriority
```
@Nullable
public Integer getPriority(Object obj)
```
    This implementation retrieves an @Priority value, allowing for additional semantics over the regular @Order annotation: typically, selecting one object over another in case of multiple matches but only one object to be returned.
    Overrides:
    getPriority in class OrderComparator
    Parameters:
    obj - the object to check
    Returns:
    the priority value, or null if none
  - sort
```
public static void sort(List<?> list)
```
    Sort the given list with a default AnnotationAwareOrderComparator.
    Optimized to skip sorting for lists with size 0 or 1, in order to avoid unnecessary array extraction.
    Parameters:
    list - the List to sort
    See Also:
    List.sort(java.util.Comparator)
  - sort
```
public static void sort(Object[] array)
```
    Sort the given array with a default AnnotationAwareOrderComparator.
    Optimized to skip sorting for lists with size 0 or 1, in order to avoid unnecessary array extraction.
    Parameters:
    array - the array to sort
    See Also:
    Arrays.sort(Object[], java.util.Comparator)
  - sortIfNecessary
```
public static void sortIfNecessary(Object value)
```
    Sort the given array or List with a default AnnotationAwareOrderComparator, if necessary. Simply skips sorting when given any other value.
    Optimized to skip sorting for lists with size 0 or 1, in order to avoid unnecessary array extraction.
    Parameters:
    value - the array or List to sort
    See Also:
    Arrays.sort(Object[], java.util.Comparator)
