Class LittleEndianInputStream

java.lang.Object

java.io.InputStream

java.io.FilterInputStream

org.docx4j.org.apache.poi.util.LittleEndianInputStream

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable, LittleEndianInput

Direct Known Subclasses:

ChunkedCipherInputStream

public class LittleEndianInputStream
extends java.io.FilterInputStream
implements LittleEndianInput

Wraps an InputStream providing LittleEndianInput

This class does not buffer any input, so the stream read position maintained by this class is consistent with that of the inner stream.
