java.lang.Object
- io.quarkus.arc.processor.BeanStream

All Implemented Interfaces:

Iterable<BeanInfo>
```
public final class BeanStream
extends Object
implements Iterable<BeanInfo>
```
Convenient Stream wrapper that can be used to filter a set of beans.
This object is stateful and cannot be reused. After a terminal opration is performed, the underlying stream is considered consumed, and can no longer be used.
This construct is not threadsafe.
