Member Function Documentation

◆ create()

bool QD3D11ShaderResourceBindings::create ( )
overridevirtual

Creates the corresponding resource binding set.

Depending on the underlying graphics API, this may involve creating native graphics resources, and therefore it should not be assumed that this is a cheap operation.

If create() has been called before with no corresponding destroy(), then destroy() is called implicitly first.

Returns
true when successful, false when failed. Regardless of the return value, calling destroy() is always safe.

Implements QRhiShaderResourceBindings.

Definition at line 4215 of file qrhid3d11.cpp.

References destroy(), and hasDynamicOffset.

Here is the call graph for this function:

◆ destroy()

void QD3D11ShaderResourceBindings::destroy ( )
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.

Note
Resources referenced by commands for the current frame should not be released until the frame is submitted by QRhi::endFrame().

The QRhiResource destructor also performs the same task, so calling this function is not necessary before deleting a QRhiResource.
