Constructor Details

ZeroFsPath

public ZeroFsPath(PathService pathService,
 Name root,
 Name... names)

ZeroFsPath

public ZeroFsPath(PathService pathService,
 Name root,
 List<Name> names)

Method Details

root

public Name root()

Returns the root name, or null if there is no root.

names

public List<Name> names()

Returns the list of name elements.

name

public Name name()

Returns the file name of this path. Unlike getFileName(), this may return the name of the root if this is a root path.

isEmptyPath

public boolean isEmptyPath()

Returns whether or not this is the empty path, with no root and a single, empty string, name.

getFileSystem

public FileSystem getFileSystem()

Specified by:

getFileSystem in interface Path

getZeroFsFileSystem

public ZeroFsFileSystem getZeroFsFileSystem()

Equivalent to getFileSystem() but with a return type of ZeroFsFileSystem. getFileSystem()'s return type is left as FileSystem to make testing paths easier (as long as methods that access the file system in some way are not called, the file system can be a fake file system instance).

isAbsolute

public boolean isAbsolute()

Specified by:

isAbsolute in interface Path

getRoot

public ZeroFsPath getRoot()

Specified by:

getRoot in interface Path

getFileName

public ZeroFsPath getFileName()

Specified by:

getFileName in interface Path

getParent

public ZeroFsPath getParent()

Specified by:

getParent in interface Path

getNameCount

public int getNameCount()

Specified by:

getNameCount in interface Path

getName

public ZeroFsPath getName(int index)

Specified by:

getName in interface Path

subpath

public ZeroFsPath subpath(int beginIndex,
 int endIndex)

Specified by:

subpath in interface Path

startsWith

private static boolean startsWith(List<?> list,
 List<?> other)

Returns true if list starts with all elements of other in the same order.

startsWith

public boolean startsWith(Path other)

Specified by:

startsWith in interface Path

startsWith

public boolean startsWith(String other)

Specified by:

startsWith in interface Path

endsWith

public boolean endsWith(Path other)

Specified by:

endsWith in interface Path

endsWith

public boolean endsWith(String other)

Specified by:

endsWith in interface Path

normalize

public ZeroFsPath normalize()

Specified by:

normalize in interface Path

isNormal

private boolean isNormal()

Returns whether or not this path is in a normalized form. It's normal if it both contains no "." names and contains no ".." names in a location other than the start of the path.

resolve

ZeroFsPath resolve(Name name)

Resolves the given name against this path. The name is assumed not to be a root name.

resolve

public ZeroFsPath resolve(Path other)

Specified by:

resolve in interface Path
