Examples of com.amazonaws.services.s3.model.S3ObjectInputStream

com.amazonaws.services.s3.model.S3ObjectInputStream
Input stream representing the content of an {@link S3Object}. In addition to the methods supplied by the {@link InputStream} class,{@link S3ObjectInputStream} supplies the abort() method, which will terminatean HTTP connection to the S3 object.
