Class PathSet

java.lang.Object

cn.wanghaomiao.maven.plugin.seimi.util.PathSet

All Implemented Interfaces:

Iterable<String>

public class PathSet
extends Object
implements Iterable<String>

Set of file's paths.

The class extends functionality of a "normal" set of strings by a process of the paths normalization. All paths are converted to unix form (slashes) and they don't start with starting /.

Constructor Detail

PathSet

public PathSet()

Creates an empty paths set

PathSet

public PathSet(Collection<String> paths)

Creates paths set and normalizate and adds all 'paths'. The source 'paths' will not be changed

Parameters:

paths - to be added

PathSet

public PathSet(String[] paths)

Creates paths set and normalizate and adds all 'paths'. The source 'paths' will not be changed

Parameters:

paths - to be added

Method Detail

normalizeFilePath

protected String normalizeFilePath(String path)

The method normalizes the path.

• changes directory separator to unix's separator(/)
• deletes all trailing slashes

Parameters:

path - to normalization

Returns:

normalized path

add

public void add(String path)

Normalizes and adds given path to the set.

Parameters:

path - to be added

addAll

public void addAll(Collection<String> paths,
          String prefix)

Normalizes and adds given paths (collection of strings) to the set. The source collection will not be changed

Parameters:

paths - - collection of strings to be added

prefix - added to all given paths

addAll

public void addAll(String[] paths,
          String prefix)

Normalizes and adds given paths to the set. The source collection will not be changed

Parameters:

paths - to be added

prefix - added to all given paths

addAll

public void addAll(PathSet paths,
          String prefix)

Adds given paths to the set. The source collection will not be changed

Parameters:

paths - to be added

prefix - added to all given paths

addAll

public void addAll(Collection<String> paths)

Normalizes and adds given paths (collection of strings) to the set. The source collection will not be changed

Parameters:

paths - - collection of strings to be added

addAll

public void addAll(String[] paths)

Normalizes and adds given paths to the set. The source collection will not be changed

Parameters:

paths - to be added

addAll

public void addAll(PathSet paths)

Adds given paths to the set. The source collection will not be changed

Parameters:

paths - to be added

contains

public boolean contains(String path)

Checks if the set constains given path. The path is normalized before check.

Parameters:

path - we are looking for in the set.

Returns:

information if the set constains the path.

iterator

public Iterator<String> iterator()

Returns iterator of normalized paths (strings)

Specified by:

iterator in interface Iterable<String>

Returns:

iterator of normalized paths (strings)

paths

public Collection<String> paths()

Returns:

pathsSet

addPrefix

public void addPrefix(String prefix)

Adds given prefix to all paths in the set.

The prefix should be ended by '/'. The generated paths are normalized.

Parameters:

prefix - to be added to all items

size

public int size()

Returns count of the paths in the set

Returns:

count of the paths in the set

addAllFilesInDirectory

public void addAllFilesInDirectory(File directory,
                          String prefix)

Adds to the set all files in the given directory

Parameters:

directory - that will be searched for file's paths to add

prefix - to be added to all found files

normalizeFilePathStatic

public static String normalizeFilePathStatic(String path)

The method normalizes the path.

• changes directory separator to unix's separator(/)
• deletes all trailing slashes

Parameters:

path - to normalization

Returns:

normalized path

trimTrailingSlashes

public static String trimTrailingSlashes(String str)

The method deletes all trailing slashes from the given string

Parameters:

str - a string

Returns:

trimed string
