hash-table-rehash-size

hash-table-rehash-size Function

Syntax:

hash-table-rehash-size hash-table → rehash-size

Arguments and Values:

hash-table—a hash table.

rehash-size—a real of type (or (integer 1 *) (float (1.0) *)).

Description:

Returns the current rehash size of hash-table, 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-size 1.4)) 
→ #<HASH-TABLE EQL 0/100 2556371> 
(hash-table-rehash-size table) → 1.4 

Exceptional Situations:

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

See Also:

make-hash-table, hash-table-rehash-threshold

Notes:

If the hash table was created with an integer rehash size, the result is an integer , indicating that the rate of growth of the hash-table when rehashed is intended to be additive; otherwise, the result

Hash

is a float, indicating that the rate of growth of the hash-table when rehashed is intended to be multiplicative. However, this value is only advice to the implementation; the actual amount by which the hash-table will grow upon rehash is implementation-dependent.
