class GzipFileSystemPathPointer(FileSystemPathPointer): (source)

Constructor: GzipFileSystemPathPointer(_path)

A subclass of FileSystemPathPointer that identifies a gzip-compressed file located at a given absolute path. GzipFileSystemPathPointer is appropriate for loading large gzip-compressed pickle objects efficiently.

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

Inherited from FileSystemPathPointer:

Method	`__init__`	Create a new path pointer for the given absolute path.
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.
Property	`path`	The absolute path identified by this path pointer.
Instance Variable	`_path`	Undocumented

def open(self, encoding=None): (source) ¶
