The abstract class for FSet functional replay sets. Subclass of set.
Returns true iff x is an FSet functional replay set.
Functional replay sets implemented as pairs of a CHAMP set and a seq. Subclass of
replay-set. These print as:
##{= e0 e1 ... }[compare-fn]
That is, there’s an = just inside the opening brace; otherwise they look like ch-sets. As
always, the comparison function is printed only if it is not compare.
Returns true iff x is an FSet functional CHAMP replay set.
The abstract class for FSet transient replay sets. Subclass of transient-set.
Returns true iff x is an FSet transient replay set.
Constructor function. Returns an empty ch-replay-set. By default, its internal set will be
organized by compare. To use a custom organization, supply the comparison function name (a
symbol) as compare-fn-name; a hash function must have been defined for it using
define-hash-function. (A custom organization will not affect
the set’s ordering for iteration or printing; the only reason you would need one is if you had a
user-defined data type for which you had not defined methods on compare and
hash-value.)
Constructor macro. Constructs a ch-replay-set according to the supplied argument subforms.
Each argument subform can be an expression, whose value will be an element of the result set; or a
list of the form ($ expression), in which case the expression must evaluate to a set
(possibly a replay set), all of whose elements become elements of the result set. Elements are
added in left-to-right order.
To use a custom organization, use ch-custom-replay-set. compare-fn-name must be a
symbol naming the desired comparison function; a hash function must have been defined for it using
define-hash-function.
