Method

WPEJavaScriptCoreContextevaluate_in_object

Declaration [src]

JSCValue*
jsc_context_evaluate_in_object (
  JSCContext* context,
  const char* code,
  gssize length,
  gpointer object_instance,
  JSCClass* object_class,
  const char* uri,
  guint line_number,
  JSCValue** object
)

Description [src]

Evaluate code and create an new object where symbols defined in code will be added as properties, instead of being added to context global object. The new object is returned as object parameter. Similar to how jsc_value_new_object() works, if object_instance is not NULL object_class must be provided too. The line_number is the starting line number in uri; the value is one-based so the first line is 1. uri and line_number will be shown in exceptions and they don’t affect the behavior of the script.

	A JavaScript script to evaluate.
	The data is owned by the caller of the function.

`line_number`	`guint`
	The starting line number.
`object`	`JSCValue`
	Return location for a `JSCValue`.
	The argument will be set by the function.
	The instance takes ownership of the data, and is responsible for freeing it.
