is_normal_form

Checks if this is in normal form.

The main reason to do this is to detect if a given chunk of serialized data is in normal form: load the data into a Variant using new_from_data and then use this function to check.

If this is found to be in normal form then it will be marked as being trusted. If the value was already marked as being trusted then this function will immediately return true.

There may be implementation specific restrictions on deeply nested values. GVariant is guaranteed to handle nesting up to at least 64 levels.

Parameters:

this	a Variant instance

Returns:

true if this is in normal form
