Interface RuntimeAsync

public interface RuntimeAsync
Runtime domain exposes JavaScript runtime by means of remote evaluation and mirror objects. Evaluation results are returned as mirror object that expose object type, string representation and unique identifier that can be used for further object reference. Original objects are maintained in memory unless they are either explicitly released or are released along with the other objects in their object group.

    • addBinding

      CompletableFuture<Void> addBinding(String name)
      If executionContextId is empty, adds binding with the given name on the global objects of all inspected contexts, including those created later, bindings survive reloads. Binding function takes exactly one argument, this argument should be string, in case of any other input, function throws an exception. Each binding function call produces Runtime.bindingCalled notification.

    • addBinding

      CompletableFuture<Void> addBinding(String name, @Deprecated Integer executionContextId, String executionContextName)
      If executionContextId is empty, adds binding with the given name on the global objects of all inspected contexts, including those created later, bindings survive reloads. Binding function takes exactly one argument, this argument should be string, in case of any other input, function throws an exception. Each binding function call produces Runtime.bindingCalled notification.
      Parameters:
      executionContextId - If specified, the binding would only be exposed to the specified execution context. If omitted and executionContextName is not set, the binding is exposed to all execution contexts of the target. This parameter is mutually exclusive with executionContextName. Deprecated in favor of executionContextName due to an unclear use case and bugs in implementation (crbug.com/1169639). executionContextId will be removed in the future.
      executionContextName - If specified, the binding is exposed to the executionContext with matching name, even for contexts created after the binding is added. See also ExecutionContext.name and worldName parameter to Page.addScriptToEvaluateOnNewDocument. This parameter is mutually exclusive with executionContextId.

      Evaluates expression on global object.
      Parameters:
      expression - Expression to evaluate.
      objectGroup - Symbolic group name that can be used to release multiple objects.
      includeCommandLineAPI - Determines whether Command Line API should be available during the evaluation.
      silent - In silent mode exceptions thrown during evaluation are not reported and do not pause execution. Overrides setPauseOnException state.
      contextId - Specifies in which execution context to perform evaluation. If the parameter is omitted the evaluation will be performed in the context of the inspected page. This is mutually exclusive with uniqueContextId, which offers an alternative way to identify the execution context that is more reliable in a multi-process environment.
      returnByValue - Whether the result is expected to be a JSON object that should be sent by value.
      generatePreview - Whether preview should be generated for the result.
      userGesture - Whether execution should be treated as initiated by user in the UI.
      awaitPromise - Whether execution should await for resulting value and return once awaited promise is resolved.
      throwOnSideEffect - Whether to throw an exception if side effect cannot be ruled out during evaluation. This implies disableBreaks below.
      timeout - Terminate execution after timing out (number of milliseconds).
      disableBreaks - Disable breakpoints during execution.
      replMode - Setting this flag to true enables let re-declaration and top-level await. Note that let variables can only be re-declared if they originate from replMode themselves.
      allowUnsafeEvalBlockedByCSP - The Content Security Policy (CSP) for the target might block 'unsafe-eval' which includes eval(), Function(), setTimeout() and setInterval() when called with non-callable arguments. This flag bypasses CSP for this evaluation and allows unsafe-eval. Defaults to true.
      uniqueContextId - An alternative way to specify the execution context to evaluate in. Compared to contextId that may be reused across processes, this is guaranteed to be system-unique, so it can be used to prevent accidental evaluation of the expression in context different than intended (e.g. as a result of navigation across process boundaries). This is mutually exclusive with contextId.
      generateWebDriverValue - Whether the result should be serialized according to https://w3c.github.io/webdriver-bidi.
      Returns:
      EvaluateResult
