comindware.core.ui/src/components/treeEditor/classes/BaseDiffMap.ts

Comindware Core UI provides the basic components like editors, lists, dropdowns, popups that we so desperately need while creating Marionette-based single-page applications.

export default class BaseDiffMap<T> extends Map {
    delete(key: string) {
        const isDeleted = super.delete(key);

        if (isDeleted && this.size === 0) {
            //TODO notify subscribers
        }

        return isDeleted;
    }
}
