GC Rooting Guide
the main types of gc thing pointer are: js::value jsobject* jsstring* jsscript* jsid note that js::value and jsid can contain pointers internally even though they are not a normal pointer type, hence their inclusion in this list.
...within spidermonkey, it is suggested that these are used in preference to the template class (gecko uses the template versions): template class typedef js::rooted<js::value> js::rootedvalue js::rooted<jsobject*> js::rootedobject js::rooted<jsstring*> js::rootedstring js::rooted<jsscript*> js::rootedscript js::rooted<jsid> js::rootedid for example, instead of this: jsobject* localobj = js_getobjectofsomesort(cx); you would write this: js::rootedobject localobj(cx, js_getobjectofsomesort(cx)); spidermonkey makes it easy to remember to use js::rooted<t> ty...
... similarly to js::rooted<t>, there are typedefs available for the main types: template class typedef js::handle<js::value> js::handlevalue js::handle<jsobject*> js::handleobject js::handle<jsstring*> js::handlestring js::handle<jsscript*> js::handlescript js::handle<jsid> js::handleid you should use js::handle<t> for all function parameters taking gc thing pointers (except out-parameters, which are described below).

...(note that both -0 and +0 are allowed, and the latter may sometimes be stored using the int32_t representation.) js::value further provides these methods combining various aspects of the above methods: js::objectornullvalue(jsobject*) returns an object value corresponding to the given non-null pointer, or a null value if the pointer is null.
