Field Detail

### softspace

    public boolean softspace

### closed

    public boolean closed

### pos

    public int pos

Constructor Detail

### cStringIO.StringIO

    public cStringIO.StringIO()

### cStringIO.StringIO

    public cStringIO.StringIO(String buffer)

Method Detail

### __setattr__

    public void __setattr__(String name,
                            PyObject value)

  Description copied from class: `PyObject`
  A variant of the __setattr__ method which accepts a String as the key. This String must be interned.

  Overrides:
    `__setattr__` in class `PyObject`
  Parameters:
    `name` - the name whose value will be set - must be an interned string .
    `value` - the value to set this name to
  See Also:
    `PyObject.__setattr__(PyString, PyObject)`

### __iternext__

    public PyObject __iternext__()

  Description copied from class: `PyObject`
  Return the next element of the sequence that this is an iterator for. Returns null when the end of the sequence is reached.

  Specified by:
    `__iternext__` in class `PyIterator`

### close

    public void close()

  Free the memory buffer.

### isatty

    public boolean isatty()

  Return false.

  Returns:
    false.

### seek

    public void seek(long pos)

  Position the file pointer to the absolute position.

  Parameters:
    `pos` - the position in the file.

### seek

    public void seek(long pos,
                     int mode)

  Position the file pointer to the position in the .

  Parameters:
    `pos` - the position in the file.
    `mode` - 0=from the start, 1=relative, 2=from the end.

### reset

    public void reset()

  Reset the file position to the beginning of the file.

### tell

    public int tell()

  Return the file position.

  Returns:
    the position in the file.

### read

    public PyString read()

  Read all data until EOF is reached. An empty string is returned when EOF is encountered immediately.

  Returns:
    A string containing the data.

### read

    public PyString read(long size)

  Read at most size bytes from the file (less if the read hits EOF). If the size argument is negative, read all data until EOF is reached. An empty string is returned when EOF is encountered immediately.

  Parameters:
    `size` - the number of characters to read.
  Returns:
    A string containing the data read.

### readline

    public PyString readline()

  Read one entire line from the file. A trailing newline character is kept in the string (but may be absent when a file ends with an incomplete line). An empty string is returned when EOF is hit immediately.

  Returns:
    data from the file up to and including the newline.

### readline

    public PyString readline(long size)

  Read one entire line from the file. A trailing newline character is kept in the string (but may be absent when a file ends with an incomplete line). If the size argument is non-negative, it is a maximum byte count (including the trailing newline) and an incomplete line may be returned.

  Returns:
    data from the file up to and including the newline.

### readlineNoNl

    public PyString readlineNoNl()

  Read and return a line without the trailing newline. Usind by cPickle as an optimization.

### readlines

    public PyObject readlines()

  Read until EOF using readline() and return a list containing the lines thus read.

  Returns:
    a list of the lines.

### readlines

    public PyObject readlines(long sizehint)

  Read until EOF using readline() and return a list containing the lines thus read.

  Returns:
    a list of the lines.

### truncate

    public void truncate()

  truncate the file at the current position.

### truncate

    public void truncate(long pos)

  truncate the file at the position pos.

### write

    public void write(PyObject obj)

  Write a string to the file.

  Parameters:
    `obj` - The data to write.

### write

    public void write(String s)

### writeChar

    public void writeChar(char ch)

  Write a char to the file. Used by cPickle as an optimization.

  Parameters:
    `ch` - The data to write.

### writelines

    public void writelines(PyObject lines)

  Write a list of strings to the file.

### flush

    public void flush()

  Flush the internal buffer. Does nothing.

### getvalue

    public PyString getvalue()

  Retrieve the entire contents of the ``file'' at any time before the StringIO object's close() method is called.

  Returns:
    the contents of the StringIO.
