Member Function Documentation

void lestes::lang::cplus::syn::pack_streamer::gc_mark ( void ) [inline, protected, virtual]

Marks the keystone.

Marks all directly reachable parts of the class. The method must be overriden for each inherited class. It should contain abc.gc_mark() for each field abc of the inherited class and call to gc_mark() of the direct ancestor of the class. Does nothing for keystone, only stops processing of ancestors.

Reimplemented from lestes::std::mem::keystone.
