Class PyFile

Method Details

• read

  public PyString read(int size)

• read

  public PyString read()

• readinto

  public int readinto(PyObject buf)

• readline

  public PyString readline(int max)

• readline

  public PyString readline()

• readlines

  public PyObject readlines(int sizehint)

• readlines

  public PyObject readlines()

• __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.

  Overrides:

  __iternext__ in class PyObject

• next

  public PyObject next()

• __enter__

  public PyObject __enter__()

• __iter__

  public PyObject __iter__()

  Description copied from class: PyObject

  Return an iterator that is used to iterate the element of this sequence. From version 2.2, this method is the primary protocol for looping over sequences.

  If a PyObject subclass should support iteration based in the __finditem__() method, it must supply an implementation of __iter__() like this:

   public PyObject __iter__() {
       return new PySequenceIter(this);
   }
   

  When iterating over a python sequence from java code, it should be done with code like this:

   for (PyObject item : seq.asIterable()) {
       // Do something with item
   }
   

  Overrides:

  __iter__ in class PyObject

• xreadlines

  public PyObject xreadlines()

• write

  public void write(String string)

• writelines

  public void writelines(PyObject lines)

• tell

  public long tell()

• seek

  public void seek(long pos, int how)

• seek

  public void seek(long pos)

• flush

  public void flush()

• close

  public void close()

• __exit__

  public void __exit__(PyObject type, PyObject value, PyObject traceback)

• truncate

  public void truncate(long position)

• truncate

  public void truncate()

• isatty

  public boolean isatty()

• fileno

  public PyObject fileno()

• toString

  public String toString()

  Overrides:

  toString in class PyObject

• getClosed

  public boolean getClosed()

• getNewlines

  public PyObject getNewlines()

• getSoftspace

  public PyObject getSoftspace()

• setSoftspace

  public void setSoftspace(PyObject obj)

• delSoftspace

  public void delSoftspace()

• __tojava__

  public Object __tojava__(Class<?> cls)

  Description copied from class: PyObject

  Equivalent to the Jython __tojava__ method. Tries to coerce this object to an instance of the requested Java class. Returns the special object Py.NoConversion if this PyObject can not be converted to the desired Java class.

  Overrides:

  __tojava__ in class PyObject

  Parameters:

  cls - the Class to convert this PyObject to.

• __del_builtin__

  public void __del_builtin__()

  Description copied from interface: FinalizableBuiltin

  FinalizableBuiltin.__del_builtin__() is the built-in's own finalizer, while FinalizablePyObjectDerived.__del_derived__() refers to an instance's in-dict __del__. A FinalizeTrigger calls FinalizablePyObjectDerived.__del_derived__() first and - if existent - FinalizableBuiltin.__del_builtin__() after that. A plain FinalizablePyObject.__del__() would behave as overridden by FinalizablePyObjectDerived.__del_derived__(), i.e. won't be called if the type implements FinalizablePyObjectDerived, while FinalizableBuiltin.__del_builtin__() is called in any case.

  Specified by:

  __del_builtin__ in interface FinalizableBuiltin

• traverse

  public int traverse(Visitproc visit, Object arg)

  Description copied from interface: Traverseproc

  Traverses all directly contained PyObjects. Like in CPython, arg must be passed unmodified to visit as its second parameter. If Visitproc.visit(PyObject, Object) returns nonzero, this return value must be returned immediately by traverse. Visitproc.visit(PyObject, Object) must not be called with a null PyObject-argument.

  Specified by:

  traverse in interface Traverseproc

• refersDirectlyTo

  public boolean refersDirectlyTo(PyObject ob)

  Description copied from interface: Traverseproc

  Optional operation. Should only be implemented if it is more efficient than calling Traverseproc.traverse(Visitproc, Object) with a visitproc that just watches out for ob. Must return false if ob is null.

  Specified by:

  refersDirectlyTo in interface Traverseproc
