## Member Enumeration Documentation

enum Ogre::HardwareBuffer::LockOptions`[inherited]`

Locking options.

Enumerator:

  HBL_NORMAL | Normal mode, ie allows read/write and contents are preserved.
  HBL_DISCARD | Discards the entire buffer while locking; this allows optimisation to be performed because synchronisation issues are relaxed. Only allowed on buffers created with the HBU_DYNAMIC flag.
  HBL_READ_ONLY | Lock the buffer for reading only. Not allowed in buffers which are created with HBU_WRITE_ONLY. Mandatory on static buffers, i.e. those created without the HBU_DYNAMIC flag.
  HBL_NO_OVERWRITE | As HBL_NORMAL, except the application guarantees not to overwrite any region of the buffer which has already been used in this frame, can allow some optimisation on some APIs.

Definition at line 121 of file OgreHardwareBuffer.h.

enum Ogre::HardwareBuffer::Usage`[inherited]`

Enums describing buffer usage; not mutually exclusive.

Enumerator:

  HBU_STATIC | Static buffer which the application rarely modifies once created. Modifying the contents of this buffer will involve a performance hit.
  HBU_DYNAMIC | Indicates the application would like to modify this buffer with the CPU fairly often. Buffers created with this flag will typically end up in AGP memory rather than video memory.
  HBU_WRITE_ONLY | Indicates the application will never read the contents of the buffer back, it will only ever write data. Locking a buffer with this flag will ALWAYS return a pointer to new, blank memory rather than the memory associated with the contents of the buffer; this avoids DMA stalls because you can write to a new memory area while the previous one is being used.

  HBU_DISCARDABLE

  Indicates that the application will be refilling the contents of the buffer regularly (not just updating, but generating the contents from scratch), and therefore does not mind if the contents of the buffer are lost somehow and need to be recreated.

  This allows and additional level of optimisation on the buffer. This option only really makes sense when combined with HBU_DYNAMIC_WRITE_ONLY.

  HBU_STATIC_WRITE_ONLY | Combination of HBU_STATIC and HBU_WRITE_ONLY.
  HBU_DYNAMIC_WRITE_ONLY | Combination of HBU_DYNAMIC and HBU_WRITE_ONLY. If you use this, strongly consider using HBU_DYNAMIC_WRITE_ONLY_DISCARDABLE instead if you update the entire contents of the buffer very regularly.
  HBU_DYNAMIC_WRITE_ONLY_DISCARDABLE | Combination of HBU_DYNAMIC, HBU_WRITE_ONLY and HBU_DISCARDABLE.

Note:
  Only call this function when the buffer is unlocked.

virtual void Ogre::HardwarePixelBuffer::readData | ( | size_t | offset,

Reads data from the buffer and places it in the memory pointed to by pDest.

Parameters:

Definition at line 340 of file OgreHardwareBuffer.h.

virtual void Ogre::HardwareBuffer::unlock | ( | void |  | ) | `[virtual, inherited]`

Releases the lock on this buffer.

Remarks:
  Locking and unlocking a buffer can, in some rare circumstances such as switching video modes whilst the buffer is locked, corrupt the contents of a buffer. This is pretty rare, but if it occurs, this method will throw an exception, meaning you must re-upload the data.

  Note that using the 'read' and 'write' forms of updating the buffer does not suffer from this problem, so if you want to be 100% sure your data will not be lost, use the 'read' and 'write' forms instead.

Reimplemented in Ogre::DefaultHardwareIndexBuffer, Ogre::GLDefaultHardwareIndexBuffer, Ogre::GLESDefaultHardwareIndexBuffer, Ogre::GLES2DefaultHardwareIndexBuffer, Ogre::DefaultHardwareVertexBuffer, Ogre::GLDefaultHardwareVertexBuffer, Ogre::GLESDefaultHardwareVertexBuffer, Ogre::GLES2DefaultHardwareVertexBuffer, Ogre::D3D11HardwareIndexBuffer, and Ogre::D3D11HardwareVertexBuffer.

|  | size_t | length,
|  | const void * | pSource,
|  | bool | discardWholeBuffer = `false`
| ) |  | `[virtual, inherited]`

Writes data to the buffer from an area of system memory; note that you must ensure that your buffer is big enough.

Parameters:

  offset | The byte offset from the start of the buffer to start writing
  length | The size of the data to write to, in bytes
  pSource | The source of the data to be written
  discardWholeBuffer | If true, this allows the driver to discard the entire buffer when writing, such that DMA stalls can be avoided; use if you can.
