NAME

src/pmc/lexinfo.pmc - LexInfo PMC

DESCRIPTION

These are the vtable functions for the lexinfo PMC.

void class_init(): Manipulate vtable->flags so that constant PMCs are created. If your inherited LexInfo is not so constant, then don't do that and provide a mark() method and set the custom_mark flag.
init_pmc(PMC *sub): Initialize the LexInfo PMC and remember the associate subroutine.
void destroy(): Frees any malloced memory held by this PMC.
METHOD void declare_lex_preg(STRING *name, INTVAL preg): Declare a lexical variable that is an alias for a PMC register. The PIR compiler calls this method in response to a ".lex STRING, PREG" directive.
INTVAL elements(): Returns the number of elements in the LexInfo hash.
void visit(visit_info *info)
void freeze(visit_info *info)
void thaw(visit_info *info): Freeze/thaw interface used during freeze/thaw of the Sub PMC. The implementation of the Hash PMC is called.
