Detailed Description

This class is a platform-independent base class for a shader resource group. It has a pointer to the resource group pool, if the user initialized the group onto a pool.

Member Function Documentation

◆ Compile()

void AZ::RHI::ShaderResourceGroup::Compile ( const ShaderResourceGroupData shaderResourceGroupData,
CompileMode  compileMode = CompileMode::Async 

Compiles the SRG with the provided data. When using Async compile mode, it queues a request that the parent pool compile this group (compilation is deferred). When using Sync compile mode the SRG compilation will happen immediately.

◆ ReportMemoryUsage()

void AZ::RHI::ShaderResourceGroup::ReportMemoryUsage ( MemoryStatisticsBuilder builder) const

This implementation does not report any memory usage. Platforms may override to report more accurate usage metrics.

Implements AZ::RHI::Resource.

◆ ResetResourceTypeIteration()

void AZ::RHI::ShaderResourceGroup::ResetResourceTypeIteration ( const ShaderResourceGroupData::ResourceType  resourceType)

Reset the iteration counter to 0 for a resource type which will ensure that the given type will be compiled for another m_updateMaskResetLatency number of Compile calls
