Class ZipInputStreamZipEntrySource

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

All Implemented Interfaces:
  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!

Nested Class Summary
`static class` `ZipInputStreamZipEntrySource.FakeZipEntry` So we can close the real zip entry and still effectively work with it.

Constructor Summary
`ZipInputStreamZipEntrySource(java.util.zip.ZipInputStream inp)` Reads all the entries from the ZipInputStream into memory, and closes the source stream.

Method Summary
`void` `close()` Indicates we are done with reading, and resources may be freed
`java.util.Enumeration<? extends java.util.zip.ZipEntry>` `getEntries()` Returns an Enumeration of all the Entries
`java.io.InputStream` `getInputStream(java.util.zip.ZipEntry zipEntry)` Returns an InputStream of the decompressed data that makes up the entry

Constructor Detail

### ZipInputStreamZipEntrySource

    public ZipInputStreamZipEntrySource(java.util.zip.ZipInputStream 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`
