# Ogre::QueuedRenderableCollection Class Reference

Lowest level collection of renderables. More...

`#include <OgreRenderQueueSortingGrouping.h>`

List of all members.

## Public Types
enum | OrganisationMode { OM_PASS_GROUP = 1, OM_SORT_DESCENDING = 2, OM_SORT_ASCENDING = 6 }
| Organisation modes required for this collection. More...
## Public Member Functions
| QueuedRenderableCollection ()
| ~QueuedRenderableCollection ()
void | clear (void)
| Empty the collection.
void | removePassGroup (Pass *p)
| Remove the group entry (if any) for a given Pass.
void | resetOrganisationModes (void)
| Reset the organisation modes required for this collection.
void | addOrganisationMode (OrganisationMode om)
| Add a required sorting / grouping mode to this collection when next used.
void | addRenderable (Pass *pass, Renderable *rend)
| Add a renderable to the collection using a given pass.
void | sort (const Camera *cam)
| Perform any sorting that is required on this collection.
void | acceptVisitor (QueuedRenderableVisitor *visitor, OrganisationMode om) const
| Accept a visitor over the collection contents.
## Protected Types
typedef std::vector < RenderablePass > | RenderablePassList
| Vector of RenderablePass objects, this is built on the assumption that vectors only ever increase in size, so even if we do clear() the memory stays allocated, ie fast.
typedef std::vector < Renderable * > | RenderableList
typedef std::map < Pass *, RenderableList *, PassGroupLess > | PassGroupRenderableMap
| Map of pass to renderable lists, this is a grouping by pass.
## Protected Member Functions
void | acceptVisitorGrouped (QueuedRenderableVisitor *visitor) const
| Internal visitor implementation.
void | acceptVisitorDescending (QueuedRenderableVisitor *visitor) const
| Internal visitor implementation.
void | acceptVisitorAscending (QueuedRenderableVisitor *visitor) const
| Internal visitor implementation.
## Protected Attributes
uint8 | mOrganisationMode
| Bitmask of the organisation modes requested.
PassGroupRenderableMap | mGrouped
| Grouped.
RenderablePassList | mSortedDescending
| Sorted descending (can iterate backwards to get ascending).
## Static Protected Attributes
static RadixSort < RenderablePassList, RenderablePass, uint32 > | msRadixSorter1
| Radix sorter for accessing sort value 1 (Pass).
static RadixSort < RenderablePassList, RenderablePass, float > | msRadixSorter2
| Radix sorter for sort value 2 (distance).
## Classes
struct | DepthSortDescendingLess
| Comparator to order objects by descending camera distance. More...
struct | PassGroupLess
| Comparator to order pass groups. More...
struct | RadixSortFunctorDistance
| Functor for descending sort value 2 for radix sort (distance). More...
struct | RadixSortFunctorPass
| Functor for accessing sort value 1 for radix sort (Pass). More...

## Detailed Description

Lowest level collection of renderables.

Remarks:
  To iterate over items in this collection, you must call the accept method and supply a QueuedRenderableVisitor. The order of the iteration, and whether that iteration is over a RenderablePass list or a 2-level grouped list which causes a visit call at the Pass level, and a call for each Renderable underneath.

Definition at line 108 of file OgreRenderQueueSortingGrouping.h.

## Member Typedef Documentation

typedef std::vector<RenderablePass> Ogre::QueuedRenderableCollection::RenderablePassList`[protected]`

Vector of RenderablePass objects, this is built on the assumption that vectors only ever increase in size, so even if we do clear() the memory stays allocated, ie fast.

Definition at line 191 of file OgreRenderQueueSortingGrouping.h.

typedef std::vector<Renderable*> Ogre::QueuedRenderableCollection::RenderableList`[protected]`

Definition at line 192 of file OgreRenderQueueSortingGrouping.h.

typedef std::map<Pass*, RenderableList*, PassGroupLess> Ogre::QueuedRenderableCollection::PassGroupRenderableMap`[protected]`

Map of pass to renderable lists, this is a grouping by pass.

Definition at line 194 of file OgreRenderQueueSortingGrouping.h.

## Member Enumeration Documentation

enum Ogre::QueuedRenderableCollection::OrganisationMode

Organisation modes required for this collection.

Remarks:
  This affects the internal placement of the items added to this collection; if only one type of sorting / grouping is to be required, then renderables can be stored only once, whilst if multiple types are going to be needed then internally there will be multiple organisations. Changing the organisation needs to be done when the collection is empty.

Enumerator:

  OM_PASS_GROUP | Group by pass.
  OM_SORT_DESCENDING | Sort descending camera distance.
  OM_SORT_ASCENDING | Sort ascending camera distance Note value overlaps with descending since both use same sort.

## Member Function Documentation

void Ogre::QueuedRenderableCollection::acceptVisitorGrouped | ( | QueuedRenderableVisitor * | visitor | ) | const`[protected]`

Internal visitor implementation.

void Ogre::QueuedRenderableCollection::acceptVisitorDescending | ( | QueuedRenderableVisitor * | visitor | ) | const`[protected]`

Internal visitor implementation.

void Ogre::QueuedRenderableCollection::acceptVisitorAscending | ( | QueuedRenderableVisitor * | visitor | ) | const`[protected]`

Internal visitor implementation.

void Ogre::QueuedRenderableCollection::clear | ( | void |  | ) |

Empty the collection.

void Ogre::QueuedRenderableCollection::removePassGroup | ( | Pass * | p | ) |

Remove the group entry (if any) for a given Pass.

Remarks:
  To be used when a pass is destroyed, such that any grouping level for it becomes useless.

void Ogre::QueuedRenderableCollection::resetOrganisationModes | ( | void |  | ) |

Reset the organisation modes required for this collection.

Remarks:
  You can only do this when the collection is empty.

  OrganisationMode

Definition at line 263 of file OgreRenderQueueSortingGrouping.h.

void Ogre::QueuedRenderableCollection::addOrganisationMode | ( | OrganisationMode | om | ) |

Add a required sorting / grouping mode to this collection when next used.

Remarks:
  You can only do this when the collection is empty.

See also:
  OrganisationMode

Definition at line 273 of file OgreRenderQueueSortingGrouping.h.

void Ogre::QueuedRenderableCollection::addRenderable | ( | Pass * | pass,
|  | Renderable * | rend |
| ) |  |  |

Add a renderable to the collection using a given pass.

void Ogre::QueuedRenderableCollection::sort | ( | const Camera * | cam | ) |

Perform any sorting that is required on this collection.

Parameters:

  | cam | The camera

void Ogre::QueuedRenderableCollection::acceptVisitor | ( | QueuedRenderableVisitor * | visitor,
|  | OrganisationMode | om |
| ) |  |  | const

Accept a visitor over the collection contents.

Parameters:

  | visitor | Visitor class which should be called back
  | om | The organisation mode which you want to iterate over. Note that this must have been included in an addOrganisationMode call before any renderables were added.
