We compose this into a few steps.
1. Decide on a removal policy for values stored in the table.
- hash-traits.h provides class templates for the two most common
- policies.
+ hash-traits.h provides class templates for the three most common
+ policies:
* typed_free_remove implements the static 'remove' member function
by calling free().
* typed_noop_remove implements the static 'remove' member function
by doing nothing.
+ * ggc_remove implements the static 'remove' member by doing nothing,
+ but instead provides routines for gc marking and for PCH streaming.
+ Use this for garbage-collected data that needs to be preserved across
+ collections.
+
You can use these policies by simply deriving the descriptor type
from one of those class template, with the appropriate argument.
