/**
 * @description A specialized output writer that uses regular expressions to process output.
 * @summary This class extends StandardOutputWriter to provide regex-based output processing.
 * It allows for pattern matching in the output stream and can trigger specific actions
 * based on matched patterns.
 *
 * @template T - The type of the resolved value, defaulting to string.
 *
 * @param cmd - The command string to be executed.
 * @param lock - A PromiseExecutor to control the asynchronous flow.
 * @param regexp - A string or RegExp to match against the output.
 * @param flags - Optional flags for the RegExp constructor, defaults to "g".
 *
 * @class
 * @example
 * ```typescript
 * import { RegexpOutputWriter } from '@decaf-ts/utils';
 * import { PromiseExecutor } from '@decaf-ts/utils';
 *
 * // Create a promise executor
 * const executor: PromiseExecutor<string, Error> = {
 *   resolve: (value) => console.log(`Resolved: ${value}`),
 *   reject: (error) => console.error(`Rejected: ${error.message}`)
 * };
 *
 * // Create a regexp output writer that matches version numbers
 * const writer = new RegexpOutputWriter('node --version', executor, /v(\d+\.\d+\.\d+)/);
 *
 * // Use the writer to handle command output
 * writer.data('v14.17.0');  // This will automatically resolve with "v14.17.0"
 * ```
