WPEJavaScriptCore.Context.evaluate_in_object

### Method

# WPEJavaScriptCore Contextevaluate_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.

#### Parameters

`code` | `const char*`
| A JavaScript script to evaluate.
| The data is owned by the caller of the function.
| The value is a NUL terminated UTF-8 string.
`length` | `gssize`
| Length of `code`, or -1 if `code` is a nul-terminated string.
`object_instance` | `gpointer`
| An object instance.
| The argument can be `NULL`.
| The data is owned by the caller of the function.
`object_class` | `JSCClass`
| A `JSCClass` or `NULL` to use the default.
| The argument can be `NULL`.
| The data is owned by the caller of the function.
`uri` | `const char*`
| The source URI.
| The data is owned by the caller of the function.
| The value is a NUL terminated UTF-8 string.
`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.

#### Return value

Returns: | `JSCValue`
| A `JSCValue` representing the last value generated by the script.
| The caller of the method takes ownership of the data, and is responsible for freeing it.
