Method Detail

deriveRelativePath

public static String deriveRelativePath(String root,
                                        String absolutePath)

Derive the relative path for absolutePath relative to root

Parameters:

root - the root to determine relativity

absolutePath - the absolute path

Returns:

the path relative to the root

find

public static Stream<Path> find(String root,
                                String pathOrPattern)
                         throws IOException

Find file paths by a glob pattern.

If a glob pattern is not provided, then this method will return a stream of one Path representation for the provided arguments (if the path exists), otherwise an empty stream.

In other words, this method will only ever return a stream of actual files which exist.

Parameters:

root - the start location to search

pathOrPattern - the path or glob pattern, i.e **/path/**/*.txt

Returns:

the collection of paths which match the pattern, or an empty collection if no matches found

Throws:

IOException - if any error occurs walking the file tree attempting to match paths

isGlobPattern

public static boolean isGlobPattern(String pattern)

Determine if the provided pattern is a glob pattern

Parameters:

pattern - the pattern to check

Returns:

true if a glob pattern, false otherwise
