ProcessIdResolver (Microsphere :: Java :: Core 0.1.6 API)

All Superinterfaces:

java.lang.Comparable<Prioritized>, Prioritized

All Known Implementing Classes:

ClassicProcessIdResolver, ModernProcessIdResolver, VirtualMachineProcessIdResolver
```
public interface ProcessIdResolver
extends Prioritized
```
A strategy interface for resolving the current process ID.
Implementations of this interface are responsible for determining the identifier of the currently running process. Different implementations may be used depending on the runtime environment or operating system.
ProcessIdResolver extends Prioritized, allowing implementations to define a priority value to influence the order in which they are considered when multiple resolvers are available.
Example Usage
```
{@code
 public class MyProcessIdResolver implements ProcessIdResolver {
     public int getPriority() {
         return ProcessIdResolver.NORMAL_PRIORITY;
     }

     public boolean supports() {
         return true; // or conditionally based on environment
     }

     public Long current() {
         return 12345L; // simulate process ID
     }
 }
```
