Detailed Description

Wrapper for D3D root parameter type.

Member Enumeration Documentation

Type

enum class ne::RootSignatureGenerator::RootParameter::Type

strong

Describes a root parameter type.

Constructor & Destructor Documentation

RootParameter() [1/2]

ne::RootSignatureGenerator::RootParameter::RootParameter ( )

default

Creates uninitialized parameter.

RootParameter() [2/2]

ne::RootSignatureGenerator::RootParameter::RootParameter	(	UINT	iBindPoint,
		UINT	iSpace,
		RootParameter::Type	type,
		bool	bIsTable = false,
		UINT	iCount = 1
	)

Initializes a root parameter.

Parameters

iBindPoint	Register binding index.
iSpace	Register space.
type	Root parameter type.
bIsTable	true to initialize this parameter as descriptor table (even if descriptor count is 1), otherwise false to initialize it as just one descriptor.
iCount	If type is table them defined the number of descriptors this parameter stores, if type is constants then the number of 32 bit constants, otherwise ignored.

Member Function Documentation

generateSingleDescriptorDescription()

CD3DX12_ROOT_PARAMETER ne::RootSignatureGenerator::RootParameter::generateSingleDescriptorDescription

(

)

const

Generates root parameter description that describes a single descriptor.

Remarks

Shows error if this parameter was initialized as descriptor table.

Returns

Root parameter description.

generateTableRange()

CD3DX12_DESCRIPTOR_RANGE ne::RootSignatureGenerator::RootParameter::generateTableRange

(

)

const

Generates root table range description.

Remarks

Shows error if this parameter was initialized as a single descriptor.

Returns

Root table range description.

getVisibility()

D3D12_SHADER_VISIBILITY ne::RootSignatureGenerator::RootParameter::getVisibility

(

)

const

Returns visibility of this parameter.

Returns

Visibility.

isTable()

bool ne::RootSignatureGenerator::RootParameter::isTable

(

)

const

Tells whether this parameter describes a descriptor table or just a single view.

Returns

true if generateTableRange should be used, otherwise generateSingleDescriptorDescription.

Member Data Documentation
