ANSI Common Lisp  18 Hash Tables 18.2 Dictionary of Hash Tables
| 18.2.5 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 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.

None.
