public final class InterIndexDiffFilter
extends TreeFilter

A filter for extracting changes between two versions of the dircache. In addition to what TreeFilter.ANY_DIFF would do, it also detects changes that will affect decorations and show up in an attempt to commit.

public InterIndexDiffFilter()

Method Detail

include

public boolean include(TreeWalk walker)

Description copied from class: TreeFilter

Determine if the current entry is interesting to report.

This method is consulted for subtree entries even if TreeWalk.isRecursive() is enabled. The consultation allows the filter to bypass subtree recursion on a case-by-case basis, even when recursion is enabled at the application level.

Specified by:

include in class TreeFilter

Parameters:

walker - the walker the filter needs to examine.

Returns:

true if the current entry should be seen by the application; false to hide the entry.

shouldBeRecursive

public boolean shouldBeRecursive()

Description copied from class: TreeFilter

Does this tree filter require a recursive walk to match everything?

If this tree filter is matching on full entry path names and its pattern is looking for a '/' then the filter would require a recursive TreeWalk to accurately make its decisions. The walker is not required to enable recursive behavior for any particular filter, this is only a hint.

Specified by:

shouldBeRecursive in class TreeFilter

Returns:

true if the filter would like to have the walker recurse into subtrees to make sure it matches everything correctly; false if the filter does not require entering subtrees.

clone

public TreeFilter clone()

Description copied from class: TreeFilter

Clone this tree filter, including its parameters.

This is a deep clone. If this filter embeds objects or other filters it must also clone those, to ensure the instances do not share mutable data.

Specified by:

clone in class TreeFilter

Returns:

another copy of this filter, suitable for another thread.

toString

public String toString()
