@wroud/preconditions/lib/IPrecondition.d.ts

A flexible and extensible library for managing preconditions in JavaScript and TypeScript applications. Simplify validation and preparation of entities like nodes, connections, and features with dynamic precondition handling.

export interface IPrecondition<T> {
    /**
     * Determines if this precondition applies to the given data.
     * @param data - The data to check applicability for.
     * @return {boolean} - True if applicable, false otherwise.
     */
    isApplicable(data: T): boolean;
    /**
     * Checks if the precondition is already fulfilled.
     * @param data - The data context.
     * @return {Promise<boolean>} - Resolves to true if fulfilled, false otherwise.
     */
    check(data: T): Promise<boolean>;

     * Attempts to fulfill the precondition.
     * @param data - The data context.
     * @return {Promise<void>}
