Member Typedef Documentation

Type

using FShaderPermutationBool::Type = bool

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

Member Function Documentation

FromDimensionValueId()

static Type FShaderPermutationBool::FromDimensionValueId ( int32  PermutationId )

inlinestatic

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

ToDefineValue()

static bool FShaderPermutationBool::ToDefineValue ( Type  E )

inlinestatic

Pass down a boolean to FShaderCompilerEnvironment::SetDefine().

ToDimensionValueId()

static int32 FShaderPermutationBool::ToDimensionValueId ( Type  E )

inlinestatic

Converts dimension boolean value to dimension's value id.

Member Data Documentation

IsMultiDimensional

constexpr bool FShaderPermutationBool::IsMultiDimensional = false

staticconstexpr

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

PermutationCount

constexpr int32 FShaderPermutationBool::PermutationCount = 2

staticconstexpr

Setup the dimension's number of permutation.
