Detailed Description

Functions which operate on weakrefs.

Function Documentation

word_t croc_weakref_push	(	CrocThread *	t,
		word_t	idx
	)

Creates and pushes a weakref from the value at slot idx.

If the value is a value type or quasi-value type, the value will just be duplicated. Otherwise, a weakref object will be created (if one hasn't been created for that object already) and pushed. This mirrors the behavior of the Croc stdlib weakref function.

Returns: the stack index of the pushed value.

word_t croc_weakref_deref	(	CrocThread *	t,
		word_t	idx
	)

Given a weakref (or a value of any value or quasi-value type) at slot idx, pushes the referenced object.

If the value is a value or quasi-value type, just duplicates the value. Otherwise, it must be a weakref object, and the weakref's referent will be pushed (or null if it was collected). This mirrors the behavior of the Croc stdlib deref function.

Returns: the stack index of the pushed value.
