Instance Methods

[hide private]

__init__(self, zipfile, entry='')
Create a new path pointer pointing at the specified entry in the given zipfile. source code

open(self, encoding=None)
Return a seekable read-only stream that can be used to read the contents of the file identified by this path pointer.

source code

file_size(self)
Return the size of the file pointed to by this path pointer, in bytes.

source code

join(self, fileid)
Return a new path pointer formed by starting at the path identified by this pointer, and then following the relative path given by fileid. source code

__repr__(self)
repr(x)

Method Details

init(self, zipfile, entry=`''`)
(Constructor)

source code

Create a new path pointer pointing at the specified entry in the given zipfile.

Raises:

IOError - If the given zipfile does not exist, or if it does not contain the specified entry.

Overrides: object.__init__

open(self, encoding=None)

source code

Return a seekable read-only stream that can be used to read the contents of the file identified by this path pointer.

Raises:

IOError - If the path specified by this pointer does not contain a readable file.

Overrides: PathPointer.open

(inherited documentation)

file_size(self)

source code

Return the size of the file pointed to by this path pointer, in bytes.

Raises:

IOError - If the path specified by this pointer does not contain a readable file.

Overrides: PathPointer.file_size

(inherited documentation)

join(self, fileid)

source code

Return a new path pointer formed by starting at the path identified by this pointer, and then following the relative path given by fileid. The path components of fileid should be seperated by forward slashes (/), regardless of the underlying file system's path seperator character.

Overrides: PathPointer.join: (inherited documentation)

repr(self)
(Representation operator)

source code

repr(x)

Overrides: object.__repr__: (inherited documentation)
