Method: WebkitRemote::Client::JsObject.for

Defined in:

lib/webkit_remote/client/runtime.rb

.for(raw_object, client, group_name) ⇒ WebkitRemote::Client::JsObject, ...

Wraps a raw object returned by the Webkit remote debugger RPC protocol.

Parameters:

• raw_object (Hash<String, Object>) —

  a JsObject instance, according to the Webkit remote debugging protocol; this is the return value of a ‘Runtime.evaluate’ RPC call

• client (WebkitRemote::Client::Runtime) —

  remote debugging client for the browser tab that owns this object

• group_name (String) —

  name of the object group that will hold this object; object groups work like memory pools

Returns:

• (WebkitRemote::Client::JsObject, Boolean, Number, String) —

  a Ruby wrapper for the given raw object; primitives get wrapped by standard Ruby classes, and objects get wrapped by JsObject instances

Raises:

• (RuntimeError)
