Class 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.

      • 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.
