Signature

sweep-gen-num-objects gen-num function

Arguments

gen-num

function

A designator for a function of one argument, the object.

Description

The function sweep-gen-num-objects applies function to all the live objects in the generation gen-num.

function should take one argument, the object. It can allocate, but if it allocates heavily the sweeping becomes unreliable. Small amounts of allocation will normally happen only in generation 0, and so will not affect sweeping of other generations.

Notes

sweep-gen-num-objects is not implemented in 32-bit LispWorks, where you can use sweep-all-objects instead.

sweep-gen-num-objects does not sweep cons objects in the Mobile GC.
