Detailed Description

class Extensible is the parent class of many classes such as userrec and chanrec.

class Extensible implements a system which allows modules to 'extend' the class by attaching data within a map associated with the object. In this way modules can store their own custom information within user objects, channel objects and server objects, without breaking other modules (this is more sensible than using a flags variable, and each module defining bits within the flag as 'theirs' as it is less prone to conflict and supports arbitary data storage).

Member Function Documentation

bool Extensible::Extend (  std::string    key, VoidPointer    p )

Extend an Extensible class. You must provide a key to store the data as, and a void* to the data (typedef VoidPointer) The data will be inserted into the map. If the data already exists, you may not insert it twice, Extensible::Extend will return false in this case. On successful extension, Extend returns true.

VoidPointer Extensible::GetExt (  std::string    key )

Get an extension item. You must provide a key name, which is case sensitive. If you provide a non-existent key name, the function returns NULL, otherwise a pointer to the item referenced by the key is returned.

bool Extensible::Shrink (  std::string    key )

Shrink an Extensible class. You must provide a key name. The given key name will be removed from the classes data. If you provide a nonexistent key (case is important) then the function will return false. Returns true on success.
