Class ZipInputStreamZipEntrySource

java.lang.Object
  org.apache.poi.openxml4j.util.ZipInputStreamZipEntrySource

All Implemented Interfaces:

java.io.Closeable, ZipEntrySource

public class ZipInputStreamZipEntrySource
extends java.lang.Object
implements ZipEntrySource

Provides a way to get at all the ZipEntries from a ZipInputStream, as many times as required. Allows a ZipInputStream to be treated much like a ZipFile, for a price in terms of memory. Be sure to call close() as soon as you're done, to free up that memory!

ZipInputStreamZipEntrySource

public ZipInputStreamZipEntrySource(ZipSecureFile.ThresholdInputStream inp)
                             throws java.io.IOException

Reads all the entries from the ZipInputStream into memory, and closes the source stream. We'll then eat lots of memory, but be able to work with the entries at-will.

Throws:

java.io.IOException

getEntries
