Constructor Summary
`UniversalIOWrapper(BufferedIOBase bufferedIO)` Contruct a UniversalIOWrapper wrapping the given BufferedIOBase.

Method Summary
`PyObject` | `getNewlines()` Return the known Newline types, as a PyObject, encountered while reading this file.
`String` | `read(int size)` Read and return up to size bytes, contained in a String.
`String` | `readall()` Read until EOF.
`String` | `readline(int size)` Read until size, newline or EOF.

### UniversalIOWrapper

    public UniversalIOWrapper(BufferedIOBase bufferedIO)

  Contruct a UniversalIOWrapper wrapping the given BufferedIOBase.

  Parameters:
    `bufferedIO` -

Method Detail

### read

    public String read(int size)

  Description copied from class: `TextIOBase`
  Read and return up to size bytes, contained in a String. Returns an empty String on EOF

  Overrides:
    `read` in class `TextIOBase`
  Parameters:
    `size` - the number of bytes to read
  Returns:
    a String containing the bytes read

### readall

    public String readall()

  Description copied from class: `TextIOBase`
  Read until EOF.

  Overrides:
    `readall` in class `TextIOBase`
  Returns:
    a String containing the bytes read

### readline

    public String readline(int size)

  Description copied from class: `TextIOBase`
  Read until size, newline or EOF. Returns an empty string if EOF is hit immediately.

  Overrides:
    `readline` in class `TextIOBase`
  Parameters:
    `size` - the number of bytes to read
  Returns:
    a String containing the bytes read

### write

    public int write(String buf)

  Description copied from class: `TextIOBase`
  Write the given String to the IO stream. Returns the number of characters written.

  Overrides:
    `write` in class `TextIOBase`
  Parameters:
    `buf` - a String value
  Returns:
    the number of characters written as an int

### seek

    public long seek(long pos,
                     int whence)

  Description copied from class: `IOBase`
  Seek to byte offset pos relative to position indicated by whence: 0 Start of stream (the default). pos should be >= 0; 1 Current position - whence may be negative; 2 End of stream - whence usually negative. Returns the new absolute position.

  Overrides:
    `seek` in class `TextIOBase`
  Parameters:
    `pos` - a long position value
    `whence` - an int whence value
  Returns:
    a long position value seeked to

### tell

    public long tell()

  Description copied from class: `IOBase`
  Return the current stream position.

  Overrides:
    `tell` in class `TextIOBase`
  Returns:
    a long position value

### getNewlines

    public PyObject getNewlines()

  Description copied from class: `TextIOBase`
  Return the known Newline types, as a PyObject, encountered while reading this file. Returns None for all modes except universal newline mode.

  Overrides:
    `getNewlines` in class `TextIOBase`
  Returns:
    a PyObject containing all encountered Newlines, or None
