Usage

From source file:io.druid.java.util.common.CompressionUtils.java

/**
 * Unzip the byteSource to the output directory. If cacheLocally is true, the byteSource is cached to local disk before unzipping.
 * This may cause more predictable behavior than trying to unzip a large file directly off a network stream, for example.
 * * @param byteSource The ByteSource which supplies the zip data
 *
 * @param byteSource   The ByteSource which supplies the zip data
 * @param outDir       The output directory to put the contents of the zip
 * @param shouldRetry  A predicate expression to determine if a new InputStream should be acquired from ByteSource and the copy attempted again
 * @param cacheLocally A boolean flag to indicate if the data should be cached locally
 *
 * @return A FileCopyResult containing the result of writing the zip entries to disk
 *
 * @throws IOException/*from  www . j  av a2  s .  c  o  m*/
