Class WeakZipFileFactory.WeakZipFile.WeakZipInputStream

java.lang.Object

java.io.InputStream

org.apache.felix.framework.util.WeakZipFileFactory.WeakZipFile.WeakZipInputStream

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

Enclosing class:

WeakZipFileFactory.WeakZipFile

class WeakZipFileFactory.WeakZipFile.WeakZipInputStream
extends java.io.InputStream

This is an InputStream wrapper that will properly reopen the underlying zip file if it is weakly closed and create the underlying input stream.

Method Detail

ensureInputStreamIsValid

private void ensureInputStreamIsValid()
                               throws java.io.IOException

This internal method ensures that the zip file is open and that the underlying input stream is valid. Upon successful completion, the underlying input stream will be valid and the local mutex will be held.

Throws:

java.io.IOException - if the was an error handling the input stream.
