| Public Member Functions inherited from QRhiCommandBuffer | |
| QRhiResource::Type | resourceType () const override |
| void | resourceUpdate (QRhiResourceUpdateBatch *resourceUpdates) |
| Sometimes committing resource updates is necessary or just more convenient without starting a render pass. | |

| Records setting a new graphics pipeline ps. | |
| void | setShaderResources (QRhiShaderResourceBindings *srb=nullptr, int dynamicOffsetCount=0, const DynamicOffset *dynamicOffsets=nullptr) |
| Records binding a set of shader resources, such as, uniform buffers or textures, that are made visible to one or more shader stages. | |
| void | setVertexInput (int startBinding, int bindingCount, const VertexInput *bindings, QRhiBuffer *indexBuf=nullptr, quint32 indexOffset=0, IndexFormat indexFormat=IndexUInt16) |
| Records vertex input bindings. | |
| void | setViewport (const QRhiViewport &viewport) |

| Records setting the active scissor rectangle specified in scissor. | |
| void | setBlendConstants (const QColor &c) |
| Records setting the active blend constants to c. | |
| void | setStencilRef (quint32 refValue) |
| Records setting the active stencil reference value to refValue. | |
| void | draw (quint32 vertexCount, quint32 instanceCount=1, quint32 firstVertex=0, quint32 firstInstance=0) |
| Records a non-indexed draw. | |
| void | drawIndexed (quint32 indexCount, quint32 instanceCount=1, quint32 firstIndex=0, qint32 vertexOffset=0, quint32 firstInstance=0) |
| Records an indexed draw. | |
| void | debugMarkBegin (const QByteArray &name) |
| Records a named debug group on the command buffer with the specified name. | |
| void | debugMarkEnd () |
| Records the end of a debug group. | |
| void | debugMarkMsg (const QByteArray &msg) |
| Inserts a debug message msg into the command stream. | |
| void | beginComputePass (QRhiResourceUpdateBatch *resourceUpdates=nullptr, BeginPassFlags flags={}) |
| Records starting a new compute pass. | |
| void | endComputePass (QRhiResourceUpdateBatch *resourceUpdates=nullptr) |
| Records ending the current compute pass. | |
| void | setComputePipeline (QRhiComputePipeline *ps) |
| Records setting a new compute pipeline ps. | |
| void | dispatch (int x, int y, int z) |
| Records dispatching compute work items, with x, y, and z specifying the number of local workgroups in the corresponding dimension. | |
| const QRhiNativeHandles * | nativeHandles () |
| void | beginExternal () |
| To be called when the application before the application is about to enqueue commands to the current pass' command buffer by calling graphics API functions directly. | |
| void | endExternal () |
| To be called once the externally added commands are recorded to the command buffer or context. | |
| double | lastCompletedGpuTime () |
| Public Member Functions inherited from QRhiResource | |

| Destructor. | |
| void | deleteLater () |
| When called without a frame being recorded, this function is equivalent to deleting the object. | |
| QByteArray | name () const |
| void | setName (const QByteArray &name) |
| Sets a name for the object. | |

Here is the call graph for this function:

overridevirtual |
Releases (or requests deferred releasing of) the underlying native graphics resources.
Safe to call multiple times, subsequent invocations will be a no-op then.
Once destroy() is called, the QRhiResource instance can be reused, by calling create() again. That will then result in creating new native graphics resources underneath.
The QRhiResource destructor also performs the same task, so calling this function is not necessary before deleting a QRhiResource.
Implements QRhiResource.
