Method Detail

getRelativePathName

public static String getRelativePathName(Path root,
                                         Path path)

Returns a relative and normalized name for a Path. This method ensures that directories have a single trailing slash in their name

Parameters:

root - the root Path to relativize against

path - the Path to get the name for

Returns:

The relative and normalized name

normalize

public static Path normalize(Path path)

Returns a normalized Path. In the case of directories, it returns the Path as it was passed in. In the case of files, it returns a Path representing the root of a filesystem mounted using FileSystems.newFileSystem(java.net.URI, java.util.Map<java.lang.String, ?>).

Parameters:

path - the Path to normalized

Returns:

the normalized path

toInputStream

public static InputStream toInputStream(Path path)

Converts a the contents of a Path to a InputStream. If the Path is a directory, compresses the full contents of the directory into the stream. If the Path is a file, the contents of the file are examined using FileSystems.newFileSystem(java.net.URI, java.util.Map<java.lang.String, ?>) starting at the root. This allows both exploded and compressed artifacts to be used interchangeably.

Parameters:

path - a Path representing either a compressed or exploded artifact

Returns:

a InputStream containing the compressed contents of the path

toInputStream

public static InputStream toInputStream(Path path,
                                        Predicate<Path> filter)

Converts a the contents of a Path to a InputStream. If the Path is a directory, compresses the full contents of the directory into the stream. If the Path is a file, the contents of the file are examined using FileSystems.newFileSystem(java.net.URI, java.util.Map<java.lang.String, ?>) starting at the root. This allows both exploded and compressed artifacts to be used interchangeably.

Parameters:

path - a Path representing either a compressed or exploded artifact

filter - a Predicate to filter the Paths that will be added to the InputStream

Returns:

a InputStream containing the compressed contents of the path
