class ZipFilePathPointer(PathPointer): (source)

Constructor: ZipFilePathPointer(zipfile, entry)

A path pointer that identifies a file contained within a zipfile, which can be accessed by reading that zipfile.

Method	`__init__`	Create a new path pointer pointing at the specified entry in the given zipfile.
Method	`__repr__`	Undocumented
Method	`__str__`	Undocumented
Method	`file_size`	Return the size of the file pointed to by this path pointer, in bytes.
Method	`join`	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 separated by forward slashes, regardless of the underlying file system's path seperator character.
Method	`open`	Return a seekable read-only stream that can be used to read the contents of the file identified by this path pointer.
Property	`entry`	The name of the file within zipfile that this path pointer points to.
Property	`zipfile`	The zipfile.ZipFile object used to access the zip file containing the entry identified by this path pointer.
Instance Variable	`_entry`	Undocumented
Instance Variable	`_zipfile`	Undocumented

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

def join(self, fileid): (source) ¶

overrides nltk.data.PathPointer.open

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

Raises
