nltk.data.FileSystemPathPointer

class documentation

class FileSystemPathPointer(PathPointer, str): (source)

Known subclasses: nltk.data.GzipFileSystemPathPointer

Constructor: FileSystemPathPointer(_path)

A path pointer that identifies a file which can be accessed directly via a given absolute path.

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.
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	`path`	The absolute path identified by this path pointer.
Instance Variable	`_path`	Undocumented

def __init__(self, _path): (source) ¶

Raises
`IOError`	If the given path does not exist.

def __repr__(self): (source) ¶

Undocumented

def __str__(self): (source) ¶

def file_size(self): (source) ¶

overrides nltk.data.PathPointer.file_size

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.

def join(self, fileid): (source) ¶

overrides nltk.data.PathPointer.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.

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

overrides nltk.data.PathPointer.open

overridden in nltk.data.GzipFileSystemPathPointer

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.

@property
path = (source) ¶

The absolute path identified by this path pointer.
