Normal user code should deal with put_attr/3, get_attr/3
and del_attr/2.
The routines in this section fetch or set the entire attribute list of a
variable. Use of these predicates is anticipated to be restricted to
printing and other special purpose operations.
- get_attrs(+Var,
-Attributes)
- Get all attributes of Var. Attributes is a term of
the form
att(Module, Value, MoreAttributes), where MoreAttributes
is
[]
- put_attrs(+Var,
-Attributes)
- Set all attributes of Var. See get_attrs/2
for a description of
Attributes.
- del_attrs(+Var)
- If Var is an attributed variable, delete all its
attributes. In all other cases, this predicate succeeds without
side-effects.
