common-lisp Hash tables Creating a hash table
Example
Hash tables are created by make-hash-table:
(defvar *my-table* (make-hash-table))
The function may take keyword parameters to further specify the behavior of the resulting hash table:
test: Selects the function used to compare keys for equality. Maybe a designator for one of the functionseq,eql,equalorequalp. The default iseq.size: A hint to the implementation about the space that may initially be required.rehash-size: If an integer (>= 1), then when doing a rehash, the hash table will increase its capacity by the specified number. If otherwise an float (> 1.0), then the hash table will increase its capacity to the product of therehash-sizeand the previous capacity.rehash-threshold: Specifies how full the hash table has to be in order to trigger a rehash.
