Method Summary

Methods
Modifier and Type	Method and Description
`java.lang.String`	`getId()` A unique id for this adjunct, typically created by the system with no meaning
`java.lang.String`	`getUniqueTag()` An optional tag used to identify adjuncts with a specific purpose, typically created by the caller.
`boolean`	`isDestroyed()` Whether the adjunct is destroyed
`boolean`	`isRunning()` Whether the adjunct is available/active, ie started and not stopped or interrupted

- Method Detail
  - getId
```
java.lang.String getId()
```
    A unique id for this adjunct, typically created by the system with no meaning
    
    Specified by:
    
    getId in interface Identifiable
  - isDestroyed
```
boolean isDestroyed()
```
    Whether the adjunct is destroyed
  - isRunning
```
boolean isRunning()
```
    Whether the adjunct is available/active, ie started and not stopped or interrupted
  - getUniqueTag
```
@Nullable
java.lang.String getUniqueTag()
```
    An optional tag used to identify adjuncts with a specific purpose, typically created by the caller. This is used to prevent multiple instances with the same purpose from being created, and to access and customize adjuncts so created.
    This will be included in the call to #getTags().
