Service Tree 1.6.1

Service Tree 1.6.1 (2017-06-03)

• CHANGE: traverseSubtree(final Node node, final int mode, final boolean includeTreeRoot, final Walk walk) is package-private because it is implementation detail.

Service Tree 1.6.0

Service Tree 1.6.0 (2017-05-13)

• ADDED: ServiceTree.Scoped interface which provides onEnterScope(Node) and onExitScope() methods.

onEnterScope is called when the service is bound to the node.

onExitScope() is called if the service is removed from the node, or the node is removed from the tree.

• ADDED: traverseChain, traverseTree, traverseSubtree variants with boolean that specifies whether the tree root should be included in the traversal.

Service Tree 1.5.2

Service Tree 1.5.2 (2017-05-13)

• ADDED: hasRootService() method, which should have existed to pair with @NonNull getRootService(). Whoops.
• ADDED: node.createChild(Object) to allow creating a child for a node without directly chatting with the tree.
• ADDED: node.removeNodeAndChildren() which removes it from its associated tree.
• CHANGE: node.removeService(String) is now public, because I shouldn't tell you how to live your life.
• READDED: serviceTree.getTreeRoot() so that you can do treeRoot.getBoundServices() if you so desire.

Service Tree 1.5.1

Service Tree 1.5.1 (2017-05-06)

• ADDED: findRoot(Node) method that finds the root for a particular node.
• ADDED: traverseChain(Node, int, Walk) method where PRE_ORDER executes the chain traversal from root to child.
• FIX: getRootService() is now marked with @NonNull as it should have been.

Service Tree 1.5.0

Service Tree 1.5.0 (2017-04-27)

• RE-ADDED: registerRootService(), unregisterRootService(), getRootService(). Sorry for the inconvenience.

Now the root CAN contain information, BUT it is no longer exposed to anyone outside the library. It should have been like this from the start.

• REMOVED: getTreeRoot().

• CHANGE: getParent() will return null for root keys instead of getTreeRoot().

• ADDED: node.getChild() and node.hasChild() methods that returns the direct child.

Service Tree 1.4.0

Service Tree 1.4.0 (2017-04-06)

• BREAKING CHANGE: removed registerRootService(), unregisterRootService(), getRootService() methods.

After thinking a lot about it, the fact that ROOT_KEY and its corresponding "root" exists is an implementation detail, and functions as a guard.

The guard should not be used to store information. If a root is needed for a tree, it should be created with createRootNode().

Every other node is a child of that node. It is preferred that the hierarchy is constructed directly by the user.

For safety sake (as the tree root is the parent of all root keys), getTreeRoot() is still kept. However, traverseChain() is preferred operation.

• BREAKING CHANGE: traverseChain(), traverseTree(), and traverseSubtree() can no longer include the "tree root" bound to the internal ROOT_KEY.

Service Tree 1.3.0

Service Tree 1.3.0 (2017-03-30)

• BREAKING CHANGE: getService() is now @NonNull instead of @Nullable, and if service is not found in the tree, exception is thrown.
• ADDED: hasService() method to check if the service exists in the given chain.
• BREAKING CHANGE: ChainWalk is merged into Walk, ChainWalk.CancellationToken merged into Walk.CancellationToken
• BREAKING CHANGE: ServiceTree.traverseChain(Node, ChainWalk) is now ServiceTree.traverseChain(Node, Walk)
• BREAKING CHANGE: Walk.execute(Node) is now Walk.execute(Node, CancellationToken)
• ENHANCEMENT: Any Walk on any subtree or chain is now cancelable using cancellationToken.cancel().

Service Tree 1.2.3

Service Tree 1.2.3 (2017-03-28)

• Add ServiceTree.traverseChain(Node, ChainWalk) method. It allows traversing the chain from a particular node through all its parents.

Service Tree 1.2.2

Service Tree 1.2.2 (2017-03-27)

• Add node.getTree() method.

Service Tree 1.2.1

Service Tree 1.2.1 (2017-03-25)

• Added getKeys() method.
