typedef memId(* | memCallback) (const Citizen *ptr) |
Public Member Functions | |
PolicyParser (Policy &policy, bool strict=true) | |
Create a Parser attached to a policy object to be loaded. More... | |
virtual | ~PolicyParser () |
destroy this factory More... | |
bool | isStrict () |
return true if this parser will be strict in adhering to syntax rules. More... | |
void | setStrict (bool strict) |
set whether this parser will be strict in adhering to syntax rules. More... | |
virtual int | parse (std::istream &is)=0 |
parse data from the input stream and load results into the attached Policy. More... | |
std::string | repr () const |
Return a string representation of a Citizen. More... | |
void | markPersistent (void) |
Mark a Citizen as persistent and not destroyed until process end. More... | |
memId | getId () const |
Return the Citizen's ID. More... | |
Policy & | getPolicy () |
return the policy object More... | |
const Policy & | getPolicy () const |
return the policy object More... | |
Static Public Member Functions | |
static bool | hasBeenCorrupted () |
Check all allocated blocks for corruption. More... | |
static memId | getNextMemId () |
Return the memId of the next object to be allocated. More... | |
static int | init () |
Called once when the memory system is being initialised. More... | |
Census | |
Provide a list of current Citizens | |
static int | census (int, memId startingMemId=0) |
How many active Citizens are there? More... | |
static void | census (std::ostream &stream, memId startingMemId=0) |
Print a list of all active Citizens to stream, sorted by ID. More... | |
static const std::vector< const Citizen * > * | census () |
Return a (newly allocated) std::vector of active Citizens sorted by ID. More... | |
callbackIDs | |
Set callback Ids. The old Id is returned | |
static memId | setNewCallbackId (memId id) |
Call the NewCallback when block is allocated. More... | |
static memId | setDeleteCallbackId (memId id) |
Call the current DeleteCallback when block is deleted. More... | |
callbacks | |
Set the New/Delete callback functions; in each case the previously installed callback is returned. These callback functions return a value which is Added to the previously registered id. The default callback functions are called default{New,Delete}Callback; you may want to set a break point in these callbacks from your favourite debugger | |
static memNewCallback | setNewCallback (memNewCallback func) |
Set the NewCallback function. More... | |
static memCallback | setDeleteCallback (memCallback func) |
Set the DeleteCallback function. More... | |
static memCallback | setCorruptionCallback (memCallback func) |
Set the CorruptionCallback function. More... | |

You are responsible for deleting it; or you can say std::unique_ptr<std::vector<Citizen const*> const> leaks(Citizen::census()); and not bother (that becomes std::unique_ptr in C++11)
