// We do not need to calculate the data MD5 hash during upload if the
// expected hash value was provided as the object's Content-MD5 header.

import org.jets3t.service.model.StorageObject; //导入方法依赖的package包/类
/**
* Creates a download package representing an S3Object that will be downloaded, and the
* target file the downloaded data will be written to.

* Downloaded data may be transformed if the S3Object is encrypted or gzipped and the
* appropriate options are set.
*
* @param object
* the object
* @param fileTarget
* the file to which downloaded (and possibly transformed) data will be written.
* @param automaticUnzip
* if true, gzipped objects will be decrypted on-the-fly as they are downloaded.
* @param automaticDecrypt
* if true, encrypted files will be decrypted on-the-fly as they are downloaded (in which
* case the encryptionPassword must be correct)
* @param encryptionPassword
* the password required to decrypt encrypted objects.
*
* @return
* a download package representing an S3Object and a taret file for the object's data.
* @throws Exception
