Detailed Description

The platform-independent base class for ShaderResourceGroupPools. Platforms should inherit from this class to implement platform-dependent pooling of shader resource groups.

Member Function Documentation

◆ CompileGroupsBegin()

void AZ::RHI::ShaderResourceGroupPool::CompileGroupsBegin ( )

Begins compilation of the pool. Cannot be called recursively.

Parameters

groupsToCompileCount if non-null, is assigned to the number of groups needing to be compiled.

◆ ComputeFragmentation()

void AZ::RHI::ShaderResourceGroupPool::ComputeFragmentation ( ) const

inlineoverrideprotectedvirtual

Compute the memory fragmentation for each constituent heap and store the results in m_memoryUsage. This method is invoked when memory statistics gathering is active.

Implements AZ::RHI::ResourcePool.

◆ GetDescriptor()

const ShaderResourceGroupPoolDescriptor & AZ::RHI::ShaderResourceGroupPool::GetDescriptor ( ) const

overridevirtual

Returns the descriptor passed at initialization time.

Implements AZ::RHI::ResourcePool.

◆ InitGroup()

ResultCode AZ::RHI::ShaderResourceGroupPool::InitGroup ( ShaderResourceGroup & srg )

Initializes the resource group and associates it with the pool. The resource group must be updated on this pool.
