Methods

afterCloneFrom

afterCloneFrom(prevNode): void

Perform any state updates on the clone of prevNode that are not already handled by the constructor call in the static clone method. If you have state to update in your clone that is not handled directly by the constructor, it is advisable to override this method but it is required to include a call to super.afterCloneFrom(prevNode) in your implementation. This is only intended to be called by $cloneWithProperties function or via a super call.

Parameters

NameType
prevNodethis

Returns

void

Example

class ClassesTextNode extends TextNode {
// Not shown: static getType, static importJSON, exportJSON, createDOM, updateDOM
__classes = new Set<string>();
static clone(node: ClassesTextNode): ClassesTextNode {
// The inherited TextNode constructor is used here, so
// classes is not set by this method.
return new ClassesTextNode(node.__text, node.__key);
}
afterCloneFrom(node: this): void {
// This calls TextNode.afterCloneFrom and LexicalNode.afterCloneFrom
// for necessary state updates
super.afterCloneFrom(node);
this.__addClasses(node.__classes);
}
// This method is a private implementation detail, it is not
// suitable for the public API because it does not call getWritable
__addClasses(classNames: Iterable<string>): this {
for (const className of classNames) {
this.__classes.add(className);
}
return this;
}
addClass(...classNames: string[]): this {
return this.getWritable().__addClasses(classNames);
}
removeClass(...classNames: string[]): this {
const node = this.getWritable();
for (const className of classNames) {
this.__classes.delete(className);
}
return this;
}
getClasses(): Set<string> {
return this.getLatest().__classes;
}
