Interface ResolvedPath

All Superinterfaces:

OutputStreamSource, PathName, WritablePathName, WriterSource

public interface ResolvedPath
extends PathName, WritablePathName

A façade for operating on a pathname in a file system for which is not known if it is a directory, a file or if it does not exist.

Instances of this interface are usually obtained from the PathNameResolver.resolve(String, String...) method hence the name resolved path.

Method Detail

createDirectory

Directory createDirectory()
                          throws FoundException,
                                 IOException

Creates a directory whose pathname is given by this object or fails if the pathname already exists.

Nonexistent parent directories are not created by this method, use createParents() if necessary.

Returns:

a façade representing a newly created directory

Throws:

FoundException - if this pathname exists (even if it is a directory)

IOException - if an I/O error occurs

createParents

ResolvedPath createParents()
                           throws IOException

Creates all nonexistent parent directories of this pathname.

Returns:

a reference to this object

Throws:

IOException - if an I/O error occurs

createRegularFile

RegularFile createRegularFile(RegularFileCreateOption... options)
                              throws FoundException,
                                     IOException

Creates a new (regular) file whose pathname is given by this object with the specified creation options or fails if the pathname already exists.

Nonexistent parent directories are not created by this method, use createParents() if necessary.

Parameters:

options - the file creation options

Returns:

a façade representing a newly created file

Throws:

FoundException - if this pathname exists (even if it is a regular file)

IOException - if an I/O error occurs

toDirectory

Directory toDirectory()
                      throws NotFoundException,
                             NotDirectoryException,
                             IOException

Returns the directory denoted by this pathname; fails if the directory does not exist or if the pathname is not a directory.

Returns:

a façade for directory only operations

Throws:

NotFoundException - if this pathname does not exist

NotDirectoryException - if this pathname exists but it is not a directory (it is a regular file for instance)

IOException - if an I/O error occurs

toDirectoryCreateIfNotFound

Directory toDirectoryCreateIfNotFound()
                                      throws NotDirectoryException,
                                             IOException

Returns the directory denoted by this pathname; creates a new directory if it does not exist or fails if the pathname is not a directory.

Nonexistent parent directories are not created by this method, use createParents() if necessary.

Returns:

a façade for directory only operations

Throws:

NotDirectoryException - if this pathname exists but it is not a directory (it is a file for instance)

IOException - if an I/O error occurs

toRegularFile

RegularFile toRegularFile()
                          throws NotFoundException,
                                 NotRegularFileException,
                                 IOException

Returns the file denoted by this pathname; fails if the file does not exist or if the pathname is not a regular file.

Returns:

a façade for regular file only operations

Throws:

NotFoundException - if this pathname does not exist

NotRegularFileException - if this pathname exists but it is not a regular file (it is a directory for instance)

IOException - if an I/O error occurs

acceptPathNameVisitor

<R,P> R acceptPathNameVisitor(PathNameVisitor<R,P> visitor,
                            P p)
                        throws IOException
