`clearCache`

Empties the cache of one memoized function.

Category: Software Development Tools > Performance and Memory

Syntax

clearCache(m)

Removes every stored result from the memoized function object m.

Description

clearCache is a method of memoized function objects. It deletes the cached inputs and outputs of m and resets its statistics, but leaves m memoized: the next call computes the result again and stores it.

Other memoized functions are not affected. To clear all of them at once use clearAllMemoizedCaches.

Input arguments

m: A matlab.lang.MemoizedFunction object returned by memoize.

Example

Clear one cache

m = memoize(@(x) x + 1);
m(1); m(1); m(2);
s = stats(m);
fprintf('hits %d, misses %d\n', s.Cache.TotalHits, s.Cache.TotalMisses)
clearCache(m)
s = stats(m);
fprintf('hits %d, misses %d\n', s.Cache.TotalHits, s.Cache.TotalMisses)

Output

hits 1, misses 2
hits 0, misses 0
