Class BeanStream

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.
