Detailed Description

template<typename TType, int32 TDimensionSize, int32 TFirstValue = 0>
struct TShaderPermutationInt< TType, TDimensionSize, TFirstValue >

Defines at compile time a permutation dimension made of int32 from 0 to N -1.

Member Typedef Documentation

Type

template<typename TType , int32 TDimensionSize, int32 TFirstValue = 0>

using TShaderPermutationInt< TType, TDimensionSize, TFirstValue >::Type = TType

Setup the dimension's type in permutation domain as integer.

Member Function Documentation

FromDimensionValueId()

template<typename TType , int32 TDimensionSize, int32 TFirstValue = 0>

static Type TShaderPermutationInt< TType, TDimensionSize, TFirstValue >::FromDimensionValueId ( int32  PermutationId )

inlinestatic

Converts dimension's value id to dimension's integer value (exact reciprocal of ToDimensionValueId).

ToDefineValue()

template<typename TType , int32 TDimensionSize, int32 TFirstValue = 0>

static int32 TShaderPermutationInt< TType, TDimensionSize, TFirstValue >::ToDefineValue ( Type  E )

inlinestatic

Pass down a int32 to FShaderCompilerEnvironment::SetDefine() even for contiguous enum classes.

ToDimensionValueId()

template<typename TType , int32 TDimensionSize, int32 TFirstValue = 0>

static int32 TShaderPermutationInt< TType, TDimensionSize, TFirstValue >::ToDimensionValueId ( Type  E )

inlinestatic

Converts dimension's integer value to dimension's value id.

Member Data Documentation

IsMultiDimensional

template<typename TType , int32 TDimensionSize, int32 TFirstValue = 0>

constexpr bool TShaderPermutationInt< TType, TDimensionSize, TFirstValue >::IsMultiDimensional = false

staticconstexpr

Setup the dimension as non multi-dimensional, so that the ModifyCompilationEnvironement's define can conventily be set up in SHADER_PERMUTATION_INT.

MaxValue

template<typename TType , int32 TDimensionSize, int32 TFirstValue = 0>

constexpr Type TShaderPermutationInt< TType, TDimensionSize, TFirstValue >::MaxValue = static_cast<Type>(TFirstValue + TDimensionSize - 1)

staticconstexpr

MinValue

template<typename TType , int32 TDimensionSize, int32 TFirstValue = 0>

constexpr Type TShaderPermutationInt< TType, TDimensionSize, TFirstValue >::MinValue = static_cast<Type>(TFirstValue)

staticconstexpr

Min and max values.

PermutationCount

template<typename TType , int32 TDimensionSize, int32 TFirstValue = 0>

constexpr int32 TShaderPermutationInt< TType, TDimensionSize, TFirstValue >::PermutationCount = TDimensionSize

staticconstexpr

Setup the dimension's number of permutation.
