## Member Function Documentation

virtual bool Ogre::PageProvider::loadProceduralPage | ( | Page * | page,
|  | PagedWorldSection * | section
| ) |  | `[virtual]`

Give a provider the opportunity to load page content procedurally.

Remarks:
  This call will happen in the main render thread so it can access GPU resources. Use prepareProceduralPage for background preparation.

Returns:
  true if the page was populated, false otherwise

Definition at line 77 of file OgrePageManager.h.

virtual bool Ogre::PageProvider::prepareProceduralPage | ( | Page * | page,
|  | PagedWorldSection * | section
| ) |  | `[virtual]`

Give a provider the opportunity to prepare page content procedurally.

Remarks:
  This call may well happen in a separate thread so it should not access GPU resources, use loadProceduralPage for that

Returns:
  true if the page was populated, false otherwise

Definition at line 70 of file OgrePageManager.h.

virtual StreamSerialiser* Ogre::PageProvider::readPageStream | ( | PageID | pageID,
|  | PagedWorldSection * | section
| ) |  | `[virtual]`

Get a serialiser set up to read Page data for the given PageID, or null if this provider cannot supply one.

Remarks:
  The StreamSerialiser returned is the responsibility of the caller to delete.

Parameters:

  pageID | The ID of the page being requested
  section | The parent section to which this page will belong

Definition at line 115 of file OgrePageManager.h.

virtual StreamSerialiser* Ogre::PageProvider::readWorldStream | ( | const String & | filename | ) | `[virtual]`

Get a serialiser set up to read PagedWorld data for the given world filename.

Remarks:
  The StreamSerialiser returned is the responsibility of the caller to delete.

Definition at line 100 of file OgrePageManager.h.

virtual bool Ogre::PageProvider::unloadProceduralPage | ( | Page * | page,
|  | PagedWorldSection * | section
| ) |  | `[virtual]`

Give a provider the opportunity to unload page content procedurally.

Remarks:
  You should not call this method directly. This call will happen in the main render thread so it can access GPU resources. Use _unprepareProceduralPage for background preparation.

Returns:
  true if the page was populated, false otherwise

Definition at line 85 of file OgrePageManager.h.

virtual bool Ogre::PageProvider::unprepareProceduralPage | ( | Page * | page,
|  | PagedWorldSection * | section
| ) |  | `[virtual]`

Give a provider the opportunity to unprepare page content procedurally.

Remarks:
  You should not call this method directly. This call may well happen in a separate thread so it should not access GPU resources, use _unloadProceduralPage for that

Returns:
  true if the page was unpopulated, false otherwise

Definition at line 93 of file OgrePageManager.h.

virtual StreamSerialiser* Ogre::PageProvider::writePageStream | ( | PageID | pageID,
|  | PagedWorldSection * | section
| ) |  | `[virtual]`

Get a serialiser set up to write Page data for the given PageID, or null if this provider cannot supply one.

Remarks:
  The StreamSerialiser returned is the responsibility of the caller to delete.

Parameters:

  pageID | The ID of the page being requested
  section | The parent section to which this page will belong

Definition at line 125 of file OgrePageManager.h.

virtual StreamSerialiser* Ogre::PageProvider::writeWorldStream | ( | const String & | filename | ) | `[virtual]`
