Deprecated.in 24.1 without replacementReturns properties of this node interesting for debugging and can be overwritten by subclasses to add their own custom properties.Returns a user-readable description of the purpose of the Node, or "" if no description is available.Retrieves the segment of guest language source code that is represented by this Node, if present; otherwise retrieves the segment represented by the nearest AST ancestor that has this information.protected final Lock
getLock()
Returns a lock object that can be used to synchronize modifications to the AST.final Node
The current parent node of this node.final RootNode
Get the root node of the tree a node belongs to.Retrieves the segment of guest language source code that is represented by this Node.final <T extends Node>

isSafelyReplaceableBy
(Node newNode) Checks if this node can be replaced by another node: tree structure & type.protected final void
notifyInserted
(Node node) Notifies the framework about the insertion of one or more nodes during execution.protected void
onReplace
(Node newNode, CharSequence reason) Intended to be implemented by subclasses ofNode
to receive a notification when the node is rewritten.final <T extends Node>

Treplace
(T newNode, CharSequence reason) Replaces this node with another node.final void
Notifies the runtime that this node specialized to a polymorphic state.protected final void
reportReplace
(Node oldNode, Node newNode, CharSequence reason) Reports thatoldNode
was replaced withnewNode
, notifying anyreplace observers
and invalidating any compiled call targets.toString()
Converts this node to a textual representation useful for debugging.

execute
Compare UTF-32 stringsa
andb
int-by-int. Returns zero ifa
andb
are equal. Ifa
is equal tob
up to its length, butb
is longer thana
, a negative value is returned. In the inverse case, a positive value is returned. Otherwise, elementsa[i]
andb[i]
at an indexi
are different. Ifa[i]
is greater thanb[i]
, a positive value is returned, otherwise a negative value is returned.- Since:
