Class HttpInputStreamWithRelease

java.lang.Object

java.io.InputStream

org.apache.hadoop.fs.swift.http.HttpInputStreamWithRelease

All Implemented Interfaces:

Closeable, AutoCloseable

public class HttpInputStreamWithRelease
extends InputStream

This replaces the input stream release class from JetS3t and AWS; # Failures in the constructor are relayed up instead of simply logged. # it is set up to be more robust at teardown # release logic is thread safe Note that the thread safety of the inner stream contains no thread safety guarantees -this stream is not to be read across streams. The thread safety logic here is to ensure that even if somebody ignores that rule, the release code does not get entered twice -and that any release in one thread is picked up by read operations in all others.
