Converts a path string, or a sequence of strings that when joined form a path string, to a
Path
. If
more
does not specify any elements then the value of the
first
parameter is the path string to convert. If
more
specifies one or more elements then each non-empty string, including
first
, is considered to be a sequence of name elements (see
Path
) and is joined to form a path string. The details as to how the Strings are joined is provider specific but typically they will be joined using the
name-separator
as the separator. For example, if the name separator is "
/
" and
getPath("/foo","bar","gus")
is invoked, then the path string
"/foo/bar/gus"
is converted to a
Path
. A
Path
representing an empty path is returned if
first
is the empty string and
more
does not contain any non-empty strings.
The parsing and conversion to a path object is inherently implementation dependent. In the simplest case, the path string is rejected, and InvalidPathException thrown, if the path string contains characters that cannot be converted to characters that are legal to the file store. For example, on UNIX systems, the NUL (\u0000) character is not allowed to be present in a path. An implementation may choose to reject path strings that contain names that are longer than those allowed by any file store, and where an implementation supports a complex path syntax, it may choose to reject path strings that are badly formed.
In the case of the default provider, path strings are parsed based on the definition of paths at the platform or virtual file system level. For example, an operating system may not allow specific characters to be present in a file name, but a specific underlying file store may impose different or additional restrictions on the set of legal characters.
This method throws InvalidPathException when the path string cannot be converted to a path. Where possible, and where applicable, the exception is created with an index value indicating the first position in the path parameter that caused the path string to be rejected.
