Detailed Description

Defines the interface to a strategy class which is responsible for deciding when Page instances are requested for addition and removal from the paging system.

Remarks

The interface is deliberately light, with no specific mention of requesting new Page instances. It is entirely up to the PageStrategy to respond to the events raised on it and to call methods on other classes (such as requesting new pages).

Constructor & Destructor Documentation

PageStrategy()

Ogre::PageStrategy::PageStrategy ( const String &  name, PageManager *  manager  )

inline

~PageStrategy()

virtual Ogre::PageStrategy::~PageStrategy ( )

inlinevirtual

Member Function Documentation

getName()

const String& Ogre::PageStrategy::getName ( void  ) const

inline

getManager()

PageManager* Ogre::PageStrategy::getManager ( ) const

inline

frameStart()

virtual void Ogre::PageStrategy::frameStart ( Real  timeSinceLastFrame, PagedWorldSection *  section  )

inlinevirtual

Called when the frame starts.

frameEnd()

virtual void Ogre::PageStrategy::frameEnd ( Real  timeElapsed, PagedWorldSection *  section  )

inlinevirtual

Called when the frame ends.

notifyCamera()

virtual void Ogre::PageStrategy::notifyCamera ( Camera *  cam, PagedWorldSection *  section  )

inlinevirtual

Called when a camera is used for any kind of rendering.

Remarks

This is probably the primary way in which the strategy will request new pages.

Parameters

cam	Camera which is being used for rendering. Class should not rely on this pointer remaining valid permanently because no notification will be given when the camera is destroyed.

Reimplemented in Ogre::Grid2DPageStrategy, and Ogre::Grid3DPageStrategy.

createData()

virtual PageStrategyData* Ogre::PageStrategy::createData ( )

pure virtual

Create a PageStrategyData instance containing the data specific to this PageStrategy.

This data will be held by a given PagedWorldSection and the structure of the data will be specific to the PageStrategy subclass.

Implemented in Ogre::Grid2DPageStrategy, and Ogre::Grid3DPageStrategy.

destroyData()

virtual void Ogre::PageStrategy::destroyData ( PageStrategyData *  d )

pure virtual

Destroy a PageStrategyData instance containing the data specific to this PageStrategy.

This data will be held by a given PagedWorldSection and the structure of the data will be specific to the PageStrategy subclass.

Implemented in Ogre::Grid2DPageStrategy, and Ogre::Grid3DPageStrategy.

updateDebugDisplay()

virtual void Ogre::PageStrategy::updateDebugDisplay ( Page *  p, SceneNode *  sn  )

pure virtual

Update the contents of the passed in SceneNode to reflect the debug display of a given page.

Remarks

The PageStrategy is to have complete control of the contents of this SceneNode, it must not be altered / added to by others.

Implemented in Ogre::Grid2DPageStrategy, and Ogre::Grid3DPageStrategy.

getPageID()

virtual PageID Ogre::PageStrategy::getPageID ( const Vector3 &  worldPos, PagedWorldSection *  section  )

pure virtual

Get the page ID for a given world position.

Returns

The page ID

Implemented in Ogre::Grid2DPageStrategy, and Ogre::Grid3DPageStrategy.
