          de.schlichtherle.io.InputArchiveMetaData.EntryInputStream

All Implemented Interfaces:

Closeable

Enclosing class:

InputArchiveMetaData

private final class InputArchiveMetaData.EntryInputStream
extends SynchronizedInputStream

An InputStream to read the entry data from an InputArchive. This input stream provides support for finalization and throws an IOException on any subsequent attempt to read data after InputArchiveMetaData.closeAllInputStreams(de.schlichtherle.io.ArchiveException) has been called.

close

public final void close()
                 throws IOException

Closes this archive entry stream and releases any resources associated with it. This method tolerates multiple calls to it: Only the first invocation closes the underlying stream.

Specified by:

close in interface Closeable

Overrides:

close in class SynchronizedInputStream

Throws:

IOException - If an I/O exception occurs.

doClose

protected void doClose()
                throws IOException

Closes the underlying stream and marks this stream as being closed. It is an error to call this method on an already closed stream. This method does not remove this stream from the pool. This method is not synchronized!

Overrides:

doClose in class SynchronizedInputStream

Throws:

IOException - If an I/O exception occurs.

mark

public void mark(int readlimit)

Overrides:

mark in class SynchronizedInputStream

reset

public void reset()
           throws IOException

Overrides:

reset in class SynchronizedInputStream

Throws:

IOException

markSupported

public boolean markSupported()

Overrides:

markSupported in class SynchronizedInputStream

finalize

protected void finalize()
                 throws Throwable

The finalizer in this class forces this archive entry input stream to close. This is used to ensure that an archive can be updated although the client may have "forgot" to close this input stream before.

Overrides:

finalize in class Object

Throws:

Throwable
