```
public abstract class BufferedInput
extends InputStream
implements ObjectInput
```
An efficient buffered implementation of data input API. It is attributed with underlying byte buffer, position and limit:
- The underlying byte buffer holds data being read. It is never null.
- The position is an index of the next byte to be read. It is never negative and is never greater than the limit.
- The limit restricts allowed values for position. It usually points to the end of available data.
The BufferedInput supports the notion of total position - an offset of the next byte to be read from the beginning of the stream. It is equal to the number of bytes read from the stream adjusted according to reposition methods like seek(long), skip(long), rewind(long) and other.
All BufferedInput implementations are required to support marking because proper marking plays a vital role in definition and implementation of certain reposition methods.
This class is not thread-safe.

    Read and return an object. This methods loads classes using a context class loader (see Thread.getContextClassLoader) or using the same classloader that loaded classes for this com.devexperts.io package when context class loader is not defined. This is a shortcut for readObject(null).
    
    Specified by:
    
    readObject in interface ObjectInput
    
    Returns:
    
    the object read from the stream

  - readObject
```
public final Object readObject(ClassLoader cl)

```
    Read and return an object with a specified class loader.
    
    Parameters:
    
    cl - the ClassLoader that will be used to load classes; null for context class loader.
    
    Returns:
    
    the object read from the stream
    
    Throws:
    
    IOException - if an I/O error occurs or if object cannot be deserialized

    Parameters:
    
    serialContext - the serial class context.

                                       throws IOException
```
    Reads Marshalled object from a byte stream with a specified marshaller. This method determines the number of marshalled bytes using Marshaller.readMarshalledLength, reads the corresponding number of bytes, and wraps them into Marshalled object instance. The result of this method is not null.
    When the serialization marshaller is used, then this method reads the same bytes as would have been been read by readObject method, so in.readObject() is mostly equivalent to in.readMarshalled(Marshaller.SERIALIZATION).getObject().
    To read an arbitrary marshalled object, this method must specify the same marshaller that was used in a marshalled object that was written by a corresponding BufferedOutput.writeMarshalled method invocation.
    
    Parameters:
    
    marshaller - a strategy that defines how an object is represented in a byte array
    
    Returns:
    
    the marshalled object
    
    Throws:
    
    IOException - if an I/O error occurs

```
public final void seek(long totalPosition)
                throws IOException
```
    Repositions this buffered input to specified total position. If specified total position is smaller than current total position, then rewind(long) operation for appropriate distance is performed; the stream has to be properly marked to support this operation. If specified total position is larger than current total position, then skip(long) operation for appropriate distance is performed until requested total position is reached; if end of stream happens before this operation can be completed then EOFException is thrown.
    
    Throws:
    
    IllegalArgumentException - if total position is negative
    
    IllegalStateException - if this stream is not marked or if attempting to rewind past the marked position
    
    IOException - if an I/O error occurs
    
    EOFException - if end of stream is reached
  - markSupported
```
public final boolean markSupported()
```
    All BufferedInput implementations support mark and reset, so this method always returns true.
    
    Overrides:
    
    markSupported in class InputStream
  - mark
```
public void mark()
```
    Marks the current position in this buffered input. A subsequent call to the reset method repositions this input at the last marked position so that subsequent reads re-read the same bytes. A subsequent call to unmark method invalidates mark without changing input position.
  - unmark
```
public void unmark()
```
    Invalidates mark position in this buffered input. This method does nothing is this input was not marked.
  - mark
```
public final void mark(int readLimit)
```
    Deprecated. This method is for compatibility with interface of InputStream class only, do not use it, because the actual value of readLimit is irrelevant for all implementations of BufferedInput. Use mark and unmark methods instead.
    
    Marks the current position in this input stream. A subsequent call to the reset() method repositions this stream at the last marked position so that subsequent reads re-read the same bytes.
    The readLimit argument tells this input stream to allow that many bytes to be read before the mark position gets invalidated. Negative value for readLimit may be used in order to invalidate the mark.
    This implementation calls mark() when readLimit >= 0 and unmark() otherwise.
    
    Overrides:
    
    mark in class InputStream
  - mark
```
public final void mark(long readLimit)

  - reset
```
public final void reset()
                 throws IllegalStateException
```
    Repositions this buffered input to the position at the time the mark method was last called on this input. If the mark method has not been called since the buffered input was created, then an IllegalStateException is thrown. Otherwise the input is reset to a state such that all the bytes read since the most recent call to mark will be resupplied to subsequent callers of the read methods, followed by any bytes that otherwise would have been the next input data as of the time of the call to reset.
    NOTE: This buffered input continues to be marked. Use unmark() after reset if mark on this input is no longer needed.
    
    Overrides:
    
    reset in class InputStream
    
    Throws:
    
    IllegalStateException - if this stream is not marked
  - rewind
```
public abstract void rewind(long n)
                     throws IllegalStateException
```
    Rewinds specified number of bytes. The input cannot be rewound past the marked position.
    
    Parameters:
    
    n - the number of bytes to rewind
    
    Throws:
    
    IllegalStateException - if this stream is not marked or if attempting to rewind past the marked position
  - checkRewind
```
protected final void checkRewind(long n)
```
    Throws appropriate exception if rewind for specified distance is impossible.
  - readToOutputStream
```
public long readToOutputStream(OutputStream out,
                               long length)
                        throws IOException
```
    Reads data from this buffered input into specified output stream. The number of bytes actually read is returned as an integer.
    
    Parameters:
    
    out - the destination output stream to write to
    
    length - maximum number of bytes to read
    
    Returns:
    
    total number of bytes read to the output stream
    
    Throws:
    
    IOException - if an I/O error occurs
  - readToDataOutput
```
public long readToDataOutput(DataOutput out,
                             long length)
                      throws IOException
```
    Reads data from this buffered input into specified data output. The number of bytes actually read is returned as an integer.
    
    Parameters:
    
    out - the destination data output to write to
    
    length - maximum number of bytes to read
    
    Returns:
    
    total number of bytes read to the data output
    
    Throws:
    
    IOException - if an I/O error occurs
  - readToByteBuffer
```
public void readToByteBuffer(ByteBuffer buffer)
                      throws IOException
```
    Reads data from this buffered input into specified byte buffer.
    
    Parameters:
    
    buffer - the destination byte buffer to write to
    
    Throws:
    
    IOException
