Selects interesting tree entries during walking.

This is an abstract interface. Applications may implement a subclass, or use one of the predefined implementations already available within this package.

Unless specifically noted otherwise a TreeFilter implementation is not thread safe and may not be shared by different TreeWalk instances at the same time. This restriction allows TreeFilter implementations to cache state within their instances during include(TreeWalk) if it is beneficial to their implementation. Deep clones created by clone() may be used to construct a thread-safe copy of an existing filter.

Path filters:

Matching pathname: org.eclipse.jgit.treewalk.filter.PathFilter

ANY_DIFF back to summary

ANY_DIFF	back to summary
public static final TreeFilter ANY_DIFF Selects only tree entries which differ between at least 2 trees. This filter also prevents a TreeWalk from recursing into a subtree if all parent trees have the identical subtree at the same path. This dramatically improves walk performance as only the changed subtrees are entered into. If this filter is applied to a walker with only one tree it behaves like `ALL`, or as though the walker was matching a virtual empty tree against the single tree it was actually given. Applications may wish to treat such a difference as "all names added". When comparing `WorkingTreeIterator` and `DirCacheIterator` applications should use `IndexDiffFilter`.

clone back to summary

clone	back to summary
public abstract TreeFilter clone() Overrides java.lang.Object.clone. Doc from java.lang.Object.clone. Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object `x`, the expression: x.clone() != x will be true, and that the expression: x.clone().getClass() == x.getClass() will be `true`, but these are not absolute requirements. While it is typically the case that: x.clone().equals(x) will be `true`, this is not an absolute requirement. By convention, the returned object should be obtained by calling `super.clone`. If a class and all of its superclasses (except `Object`) obey this convention, it will be the case that `x.clone().getClass() == x.getClass()`. By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by `super.clone` before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by `super.clone` need to be modified. 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. Returns:TreeFilter a clone of this instance. Annotations @Override
