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).

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.

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.

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

Called when the frame ends.

Definition at line 93 of file OgrePageStrategy.h.

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

Called when the frame starts.

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

Definition at line 88 of file OgrePageStrategy.h.

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

Definition at line 87 of file OgrePageStrategy.h.

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.

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

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.

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.
