Member Function Documentation

◆ _forceReleaseBufferCopies() [1/2]

virtual void Ogre::v1::HardwareBufferManagerBase::_forceReleaseBufferCopies ( const HardwareVertexBufferSharedPtr &  sourceBuffer)
virtualinherited

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

Reimplemented in Ogre::v1::HardwareBufferManager.

Referenced by Ogre::v1::HardwareBufferManager::_forceReleaseBufferCopies(), and Ogre::v1::HardwareBufferManager::_forceReleaseBufferCopies().

◆ _forceReleaseBufferCopies() [2/2]

virtual void Ogre::v1::HardwareBufferManagerBase::_forceReleaseBufferCopies ( HardwareVertexBuffer *  sourceBuffer)
virtualinherited

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

Reimplemented in Ogre::v1::HardwareBufferManager.

◆ _freeUnusedBufferCopies()

virtual void Ogre::v1::HardwareBufferManagerBase::_freeUnusedBufferCopies ( void  )
virtualinherited

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).

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

BufferLicenseType  licenseType,
HardwareBufferLicensee *  licensee,
bool  copyData = false 
)
virtualinherited

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

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.

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
bufferCopyThe 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.

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