obspy.core.util.base.NamedTemporaryFile

class NamedTemporaryFile(dir=None, suffix='.tmp', prefix='obspy-')

Bases: io.BufferedIOBase

Weak replacement for the Python’s tempfile.TemporaryFile.

This class is a replacement for tempfile.NamedTemporaryFile() but will work also with Windows 7/Vista’s UAC.

Parameters

• dir (str) – If specified, the file will be created in that directory, otherwise the default directory for temporary files is used.

• suffix (str) – The temporary file name will end with that suffix. Defaults to '.tmp'.

Example

>>> with NamedTemporaryFile() as tf:
...     _ = tf.write(b"test")
...     os.path.exists(tf.name)
True
>>> # when using the with statement, the file is deleted at the end:
>>> os.path.exists(tf.name)
False

>>> with NamedTemporaryFile() as tf:
...     filename = tf.name
...     with open(filename, 'wb') as fh:
...         _ = fh.write(b"just a test")
...     with open(filename, 'r') as fh:
...         print(fh.read())
just a test
>>> # when using the with statement, the file is deleted at the end:
>>> os.path.exists(tf.name)
False

Special Methods

NamedTemporaryFile.__del__()

NamedTemporaryFile.__delattr__(name, /)

Implement delattr(self, name).

NamedTemporaryFile.__dir__()

Default dir() implementation.

NamedTemporaryFile.__enter__()

NamedTemporaryFile.__eq__(value, /)

Return self==value.

NamedTemporaryFile.__exit__(exc_type, exc_val, exc_tb)

NamedTemporaryFile.__format__(format_spec, /)

Default object formatter.

NamedTemporaryFile.__ge__(value, /)

Return self>=value.

NamedTemporaryFile.__getattribute__(name, /)

Return getattr(self, name).

NamedTemporaryFile.__gt__(value, /)

Return self>value.

NamedTemporaryFile.__hash__()

Return hash(self).

NamedTemporaryFile.__init__(dir=None, suffix='.tmp', prefix='obspy-')

NamedTemporaryFile.__init_subclass__()

This method is called when a class is subclassed.

The default implementation does nothing. It may be overridden to extend subclasses.

NamedTemporaryFile.__iter__()

Implement iter(self).

NamedTemporaryFile.__le__(value, /)

Return self<=value.

NamedTemporaryFile.__lt__(value, /)

Return self<value.

NamedTemporaryFile.__ne__(value, /)

Return self!=value.

NamedTemporaryFile.__new__(**kwargs)

NamedTemporaryFile.__next__()

Implement next(self).

NamedTemporaryFile.__reduce__()

Helper for pickle.

NamedTemporaryFile.__reduce_ex__(protocol, /)

Helper for pickle.

NamedTemporaryFile.__repr__()

Return repr(self).

NamedTemporaryFile.__setattr__(name, value, /)

Implement setattr(self, name, value).

NamedTemporaryFile.__sizeof__()

Size of object in memory, in bytes.

NamedTemporaryFile.__str__()

Return str(self).

NamedTemporaryFile.__subclasshook__()

Abstract classes can override this to customize issubclass().

This is invoked early on by abc.ABCMeta.__subclasscheck__(). It should return True, False or NotImplemented. If it returns NotImplemented, the normal algorithm is used. Otherwise, it overrides the normal algorithm (and the outcome is cached).
