A map table allows for entities to be mapped (hash index) onto it.
Unlike with Assoc, This form of map table also allows objects to be removed from the table. This table also includes a mutex lock for thread safety. A free list is also optionally maintained for reusable maps.

◆ MapTable()
ost::MapTable::MapTable |
( |
unsigned |
size | ) |
|
Create a map table with a specified number of slots.
- Parameters
-
◆ ~MapTable()
virtual ost::MapTable::~MapTable |
( |
| ) |
|
|
virtual |
Destroy the table, calls cleanup.
◆ addFree()
void ost::MapTable::addFree |
( |
MapObject * |
obj | ) |
|
Add an object to the managed free list.
Some MapObject's may override delete operator to detach and do this.
- Parameters
-
◆ addObject()
void ost::MapTable::addObject |
( |
MapObject & |
obj | ) |
|
Map an object to our table.
If it is in another table already, it is removed there first.
- Parameters
-
◆ cleanup()
void ost::MapTable::cleanup |
( |
void |
| ) |
|
|
protected |
◆ getEnd()
void* ost::MapTable::getEnd |
( |
| ) |
|
|
inline |
Get table's end, useful for cycle control; it is returned as void * for easy re-cast.
- Returns
- pointer to found object or NULL.
◆ getFirst()
void* ost::MapTable::getFirst |
( |
| ) |
|
Get the first element into table, it is returned as void * for easy re-cast.
- Returns
- pointer to found object or NULL.
◆ getFree()
void* ost::MapTable::getFree |
( |
void |
| ) |
|
Get next object from managed free list.
This returns as a void so it can be recast into the actual type being used in derived MapObject's. A derived version of MapTable may well offer an explicit type version of this. Some derived MapObject's may override new to use managed list.
- Returns
- next object on free list.
◆ getIndex()
virtual unsigned ost::MapTable::getIndex |
( |
const char * |
id | ) |
|
|
virtual |
Get index value from id string.
This function can be changed as needed to provide better collision avoidence for specific tables.
- Parameters
-
- Returns
- index slot in table.
◆ getLast()
void* ost::MapTable::getLast |
( |
| ) |
|
Get the last element into table, it is returned as void * for easy re-cast.
- Returns
- pointer to found object or NULL.
◆ getObject()
void* ost::MapTable::getObject |
( |
const char * |
id | ) |
|
Lookup an object by id key.
It is returned as void * for easy re-cast.
- Parameters
-
- Returns
- pointer to found object or NULL.
◆ getRange()
unsigned ost::MapTable::getRange |
( |
void |
| ) |
|
|
inline |
Return range of this table.
- Returns
- table range.
◆ getSize()
unsigned ost::MapTable::getSize |
( |
void |
| ) |
|
|
inline |
Return the number of object stored in this table.
- Returns
- table size.
◆ operator+=()
An operator to map an object to the table.
- Returns
- table being used.
- Parameters
-
◆ operator-=()
This operator is virtual in case it must also add the object to a managed free list.
- Returns
- current table.
- Parameters
-
◆ MapIndex
◆ MapObject
◆ count
unsigned ost::MapTable::count |
|
protected |
◆ map
◆ range
unsigned ost::MapTable::range |
|
protected |
