Method Detail

public int compare(ServiceReference<?> o1, ServiceReference<?> o2)

Implements java.util.Comparator.compare.

Doc from java.util.Comparator.compare.

Compares its two arguments for order. Returns a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.

The implementor must ensure that signum(compare(x, y)) == -signum(compare(y, x)) for all x and y. (This implies that compare(x, y) must throw an exception if and only if compare(y, x) throws an exception.)

The implementor must also ensure that the relation is transitive: ((compare(x, y)>0) && (compare(y, z)>0)) implies compare(x, z)>0.

Finally, the implementor must ensure that compare(x, y)==0 implies that signum(compare(x, z))==signum(compare(y, z)) for all z.

Annotations
@Override
getPriorityback to summary
public static int getPriority(Object o)

Checks the given instance for a @Priority annotation. If present the annotation's value is evaluated. If no such annotation is present, a default priority 1 is returned.

Parameters
o:Object

the instance, not null.

Returns:int

a priority, by default 1.

getPriorityback to summary
public static int getPriority(Class<?> type)

Checks the given type optionally annotated with a @Priority. If present the annotation's value is evaluated. If no such annotation is present, a default priority 1 is returned.

Parameters
type:Class<?>

the type, not null.

Returns:int

a priority, by default 1.
