PooledByteBufferOutputStream

extends OutputStream
java.lang.Object
   ↳ java.io.OutputStream
     ↳ com.facebook.imagepipeline.memory.PooledByteBufferOutputStream

Class Overview

An OutputStream that produces a PooledByteBuffer.

Expected use for such stream is to first write sequence of bytes to the stream and then call toByteBuffer to produce PooledByteBuffer containing written data. After toByteBuffer returns client can continue writing new data and call toByteBuffer over and over again.

Streams implementing this interface are closeable resources and need to be closed in order to release underlying resources. Close is idempotent operation and after stream was closed, no other method should be called. Streams subclassing PooledByteBufferOutputStream are not allowed to throw IOException from close method.
