Function hash-table-rehash-threshold

Syntax:

Arguments and Values:

hash-table—a hash table.

rehash-threshold—a real of type (real 0 1). KMP thinks HASH-TABLE-SIZE:INTENDED-ENTRIES implies this can no longer be an integer. Moon concurs.

Description:

Returns the current rehash threshold of hash-table, which is suitable for use in a call to make-hash-table in order to produce a hash table with state corresponding to the current state of the hash-table.

Examples:

 (setq table (make-hash-table :size 100 :rehash-threshold 0.5))
→ #<HASH-TABLE EQL 0/100 2562446>
 (hash-table-rehash-threshold table) → 0.5

Side Effects:

None.

Affected By:

None.

Exceptional Situations:

Should signal an error of type type-error if hash-table is not a hash table.
