getPath

public String getPath(Character separator)

Returns the path representation of this entity. Each entity in the path is separated with the separator. The path returned by this method without changing the separator can be used with Directory.getDirectory or Directory.getFile on the root directory of the filesystem to get this entity again.

hashCode

public Integer hashCode()

isRoot

public Boolean isRoot()

Returns if this directory is the root of its FileSystem.

size

public Long size()

Returns the size of this directory. The size of the directory will be the sum of all files and directories. This means the size will be calculated recursively. If the directory does not exist the size will be -1

Properties

parent

private final Directory parent
