Method Detail

create

public static PathSuffixFilter create(String path)
Create a new tree filter for a user supplied path.

Path strings use '/' to delimit directories on all platforms.

Parameters:
path - the path (suffix) to filter on. Must not be the empty string.
Returns:
a new filter for the requested path.
Throws:
IllegalArgumentException - the path supplied was the empty string.

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.

include

public boolean include(TreeWalk walker)
                throws MissingObjectException,
                       IncorrectObjectTypeException,
                       IOException
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.
Throws:
MissingObjectException - an object the filter needs to consult to determine its answer does not exist in the Git repository the walker is operating on. Filtering this current walker entry is impossible without the object.
IncorrectObjectTypeException - an object the filter needed to consult was not of the expected object type. This usually indicates a corrupt repository, as an object link is referencing the wrong type.
IOException - a loose object or pack file could not be read to obtain data necessary for the filter to make its decision.

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.
