Method Details

deleteDirectory

public static int deleteDirectory(String dir)

deletes all files in a given directory

copy

public static int copy(String dir,
 String target)

copies all files in a given directory to the given target

move

public static int move(String dir,
 String target)

moves all files in a given directory to the given target

foreach

public static <RESULT> Collection<RESULT> foreach(String dir,
 String includes,
 String excludes,
 String contentRegEx,
 Function<Path,RESULT> fct)

Type Parameters:

RESULT - function result type, to be collected as return value

Parameters:

dir - base directory to start on

includes - optional file name include regular expression

excludes - optional file name exclude regular expression

contentRegEx - regular expression to be matched inside the files content

fct - action to do if file name and content matches

Returns:

all results of all function calls

recurse

public static <R> int recurse(String dir,
 String includes,
 String excludes,
 Function<Path,R> action)

as Paths.get(file).foreach(consumer) walks only the path elements itself from root, this walks through all recursive files/paths starting on given dir.

Parameters:

dir - base directory to start on

includes - optional file name include regular expression

excludes - optional file name exclude regular expression

action - if file name matches, this function will be executed. if the function returns a value != null, the result count will be increased.

Returns:

count of function calls with result != null

read

public static byte[] read(String file)

write

public static Path write(String file,
 byte[] bytes)

getFileWriter

public static BufferedWriter getFileWriter(String file)
