  - read
```
public int read()
         throws java.io.IOException
```
    Reads a byte of data from this XFile.
    
    Specified by:
    
    read in class java.io.InputStream
    
    Returns:
    
    the next byte of data, or -1 if the end of the file is reached.
    
    Throws:
    
    java.io.IOException - if an I/O error occurs.
  - read
```
public int read(byte[] b)
         throws java.io.IOException
```
    Reads up to b.length bytes of data from this file into an array of bytes.
    
    Overrides:
    
    read in class java.io.InputStream
    
    Parameters:
    
    b - the buffer into which the data is read.
    
    Returns:
    
    the total number of bytes read into the buffer, or -1 if there is no more data because the end of the file has been reached.
    
    Throws:
    
    java.io.IOException - if an I/O error occurs.
  - read
```
public int read(byte[] b,
                int off,
                int len)
         throws java.io.IOException
```
    Reads up to len bytes of data from this file into an array of bytes.
    
    Overrides:
    
    read in class java.io.InputStream
    
    Parameters:
    
    b - the buffer into which the data is read.
    
    off - the start offset of the data.
    
    len - the maximum number of bytes read.
    
    Returns:
    
    the total number of bytes read into the buffer, or -1 if there is no more data because the end of the file has been reached.
    
    Throws:
    
    java.io.IOException - if an I/O error occurs.
  - available
```
public int available()
              throws java.io.IOException
```
    Returns the number of bytes yet to be read from this file.
    
    Overrides:
    
    available in class java.io.InputStream
    
    Returns:
    
    the number of bytes yet to be read from this file without blocking.
    
    Throws:
    
    java.io.IOException - if an I/O error occurs.
  - skip
```
public long skip(long n)
          throws java.io.IOException
```
    Skips over and discards n bytes of data from the file. The skip method may, for a variety of reasons, end up skipping over some smaller number of bytes, possibly 0. The actual number of bytes skipped is returned.
    
    Overrides:
    
    skip in class java.io.InputStream
    
    Parameters:
    
    n - the number of bytes to be skipped.
    
    Returns:
    
    the actual number of bytes skipped.
    
    Throws:
    
    java.io.IOException - if an I/O error occurs.
  - close
```
public void close()
           throws java.io.IOException
```
    Closes this file input stream and releases any system resources associated with the stream. After the file is closed further I/O operations may throw IOException.
    
    Specified by:
    
    close in interface java.io.Closeable
    
    Specified by:
    
    close in interface java.lang.AutoCloseable
    
    Overrides:
    
    close in class java.io.InputStream
    
    Throws:
    
    java.io.IOException - if an I/O error occurs.
