Method Detail

close

public void close()
           throws IOException

Closes the database.

If you are using FileMode.MEMORY_MAPPED, this will not unmap the underlying file due to a limitation in Java's MappedByteBuffer. It will however set the reference to the buffer to null, allowing the garbage collector to collect it.
