Member Function Documentation

virtual void Ogre::HardwareBufferManagerBase::_forceReleaseBufferCopies ( const HardwareVertexBufferSharedPtr & sourceBuffer ) [virtual, inherited]

Internal method that forces the release of copies of a given buffer.

Remarks:: This usually means that the buffer which the copies are based on has been changed in some fundamental way, and the owner of the original wishes to make that known so that new copies will reflect the changes.

Parameters:

sourceBuffer The source buffer as a shared pointer. Any buffer copies created from the source buffer are deleted.

Reimplemented in Ogre::HardwareBufferManager.

virtual void Ogre::HardwareBufferManagerBase::_forceReleaseBufferCopies ( HardwareVertexBuffer * sourceBuffer ) [virtual, inherited]

Internal method that forces the release of copies of a given buffer.

Remarks:: This usually means that the buffer which the copies are based on has been changed in some fundamental way, and the owner of the original wishes to make that known so that new copies will reflect the changes.

Parameters:

sourceBuffer The source buffer as a pointer. Any buffer copies created from the source buffer are deleted.

Reimplemented in Ogre::HardwareBufferManager.

virtual void Ogre::HardwareBufferManagerBase::_freeUnusedBufferCopies ( void ) [virtual, inherited]

Free all unused vertex buffer copies.

Remarks:: This method free all temporary vertex buffers that not in used. In normally, temporary vertex buffers are subsequently stored and can be made available for other purposes later without incurring the cost of construction / destruction. But in some cases you want to free them to save hardware memory (e.g. application was runs in a long time, you might free temporary buffers periodically to avoid memory overload).

Reimplemented in Ogre::HardwareBufferManager.

void Ogre::HardwareBufferManagerBase::_notifyCounterBufferDestroyed ( HardwareCounterBuffer * buf ) [inherited]

Notification that at hardware counter buffer has been destroyed.

void Ogre::HardwareBufferManagerBase::_notifyIndexBufferDestroyed ( HardwareIndexBuffer * buf ) [inherited]

Notification that a hardware index buffer has been destroyed.

Reimplemented in Ogre::HardwareBufferManager.

void Ogre::HardwareBufferManagerBase::_notifyUniformBufferDestroyed ( HardwareUniformBuffer * buf ) [inherited]

Notification that at hardware uniform buffer has been destroyed.

Reimplemented in Ogre::HardwareBufferManager.

void Ogre::HardwareBufferManagerBase::_notifyVertexBufferDestroyed ( HardwareVertexBuffer * buf ) [inherited]

Notification that a hardware vertex buffer has been destroyed.

Reimplemented in Ogre::HardwareBufferManager.

virtual void Ogre::HardwareBufferManagerBase::_releaseBufferCopies ( bool forceFreeUnused = false ) [virtual, inherited]

Internal method for releasing all temporary buffers which have been allocated using BLT_AUTOMATIC_RELEASE; is called by OGRE.

Parameters:

forceFreeUnused If true, free all unused temporary buffers. If false, auto detect and free all unused temporary buffers based on temporary buffers utilization.

Reimplemented in Ogre::HardwareBufferManager.

virtual HardwareVertexBufferSharedPtr Ogre::HardwareBufferManagerBase::allocateVertexBufferCopy	(	const HardwareVertexBufferSharedPtr &	sourceBuffer,
		BufferLicenseType	licenseType,
		HardwareBufferLicensee *	licensee,
		bool	copyData = `false`
	)		`[virtual, inherited]`

Allocates a copy of a given vertex buffer.

Remarks:: This method allocates a temporary copy of an existing vertex buffer. This buffer is subsequently stored and can be made available for other purposes later without incurring the cost of construction / destruction.

Parameters:

sourceBuffer	The source buffer to use as a copy.
licenseType	The type of license required on this buffer - automatic release causes this class to release licenses every frame so that they can be reallocated anew.
licensee	Pointer back to the class requesting the copy, which must implement HardwareBufferLicense in order to be notified when the license expires.
copyData	If `true`, the current data is copied as well as the structure of the buffer/

virtual void Ogre::HardwareBufferManagerBase::registerVertexBufferSourceAndCopy	(	const HardwareVertexBufferSharedPtr &	sourceBuffer,
		const HardwareVertexBufferSharedPtr &	copy
	)		`[virtual, inherited]`

Registers a vertex buffer as a copy of another.

Remarks:: This is useful for registering an existing buffer as a temporary buffer which can be allocated just like a copy.

Remarks:: Method for dealing with lost devices.

virtual void Ogre::HardwareBufferManagerBase::releaseVertexBufferCopy ( const HardwareVertexBufferSharedPtr & bufferCopy ) [virtual, inherited]

Manually release a vertex buffer copy for others to subsequently use.

Remarks:: Only required if the original call to allocateVertexBufferCopy included a licenseType of BLT_MANUAL_RELEASE.

Parameters:

bufferCopy The buffer copy. The caller is expected to delete or at least no longer use this reference, since another user may well begin to modify the contents of the buffer.

Reimplemented in Ogre::HardwareBufferManager.

virtual void Ogre::HardwareBufferManagerBase::touchVertexBufferCopy ( const HardwareVertexBufferSharedPtr & bufferCopy ) [virtual, inherited]

Tell engine that the vertex buffer copy intent to reuse.

Remarks:: Ogre internal keep an expired delay counter of BLT_AUTOMATIC_RELEASE buffers, when the counter count down to zero, it'll release for other purposes later. But you can use this function to reset the counter to the internal configured value, keep the buffer not get released for some frames.

Parameters:

bufferCopy The buffer copy. The caller is expected to keep this buffer copy for use.

Reimplemented in Ogre::HardwareBufferManager.
