public class FileTreeIterator
extends WorkingTreeIterator

Working directory iterator for standard Java IO.

This iterator uses the standard java.io package to read the specified working directory as part of a TreeWalk.

Field Detail

directory

protected final File directory

the starting directory. This directory should correspond to the root of the repository.

fs

protected final FS fs

the file system abstraction which will be necessary to perform certain file system operations.

Constructor Detail

FileTreeIterator

public FileTreeIterator(Repository repo)

Create a new iterator to traverse the work tree and its children.

Parameters:

repo - the repository whose working tree will be scanned.

FileTreeIterator

public FileTreeIterator(File root,
                FS fs,
                WorkingTreeOptions options)

Create a new iterator to traverse the given directory and its children.

Parameters:

root - the starting directory. This directory should correspond to the root of the repository.

fs - the file system abstraction which will be necessary to perform certain file system operations.

options - working tree options to be used

FileTreeIterator

protected FileTreeIterator(WorkingTreeIterator p,
                File root,
                FS fs)

Create a new iterator to traverse a subdirectory.

Parameters:

p - the parent iterator we were created from.

fs - the file system abstraction which will be necessary to perform certain file system operations.

root - the subdirectory. This should be a directory contained within the parent directory.

Method Detail

createSubtreeIterator

public AbstractTreeIterator createSubtreeIterator(ObjectReader reader)
                                           throws IncorrectObjectTypeException,
                                                  IOException

Description copied from class: AbstractTreeIterator

Create a new iterator for the current entry's subtree.

The parent reference of the iterator must be this, otherwise the caller would not be able to exit out of the subtree iterator correctly and return to continue walking this.

Specified by:

createSubtreeIterator in class AbstractTreeIterator

Parameters:

reader - reader to load the tree data from.

Returns:

a new parser that walks over the current subtree.

Throws:

IncorrectObjectTypeException - the current entry is not actually a tree and cannot be parsed as though it were a tree.

IOException - a loose object or pack file could not be read.

getDirectory

public File getDirectory()

Returns:

The root directory of this iterator

getEntryFile

public File getEntryFile()

Returns:

The location of the working file. This is the same as new File(getDirectory(), getEntryPath()) but may be faster by reusing an internal File instance.

idSubmodule

protected byte[] idSubmodule(WorkingTreeIterator.Entry e)

Description copied from class: WorkingTreeIterator

Get submodule id for given entry.

Overrides:

idSubmodule in class WorkingTreeIterator

Returns:

non-null submodule id
