Class DirectoryTree

java.lang.Object

de.unihalle.informatik.MiToBo.core.datatypes.MTBTree

de.unihalle.informatik.MiToBo.io.dirs.DirectoryTree

All Implemented Interfaces:

Cloneable

public class DirectoryTree
extends MTBTree

This class implements a data structure for representing directory trees.

It is based on a conventional tree data structure, but provides methods for directly parsing a directory structure into the tree. Additionally, the class provides methods for getting a list of all files in all directories below the given root directory.

Field Detail

mainpath

private String mainpath

Root directory of the tree.

recursiveProcessing

private boolean recursiveProcessing

Flag for recursive processing of sub-directories.

Constructor Detail

DirectoryTree

public DirectoryTree(String dir)

Standard constructor.

Parameters:

dir - Root directory where to begin the parsing.

DirectoryTree

public DirectoryTree(String dir,
                     boolean recursiveFlag)

Constructor.

Parameters:

dir - Root directory where to begin the parsing.

recursiveFlag - Recursive processing of sub-directories.

Method Detail

getFileList

public Vector<String> getFileList()

Collect all files in the directory tree including their complete paths.

Returns:

vector containing all files with absolute path

getSubdirectoryList

public Vector<String> getSubdirectoryList()

Get a list of all subdirectories in the root folder.

Note that the result list includes directory names including their complete absolute paths.

The root folder by itself is not element of the list.

Returns:

Vector containing all sub-directories with absolute paths.

initFromDirectory

private void initFromDirectory()

Builds the directory tree by initiating the (recursive) parse procedure.

traverseSubdir

private static MTBTreeNode traverseSubdir(String path,
                                          String subdir)

Recursive traversal of subdirectories.

Parameters:

path - Absolute path to parent directory.

subdir - The subdirectory name to be analyzed.

Returns:

Tree node for the subdirectory.
