inline

Utility functions used for in-place swizzle operation

PeekValue()

FPreshaderValue UE::Shader::FPreshaderStack::PeekValue

(

int32

Offset = 0

)

PopResult()

void UE::Shader::FPreshaderStack::PopResult

(

FPreshaderValue &

OutValue

)

Pops the final result from the stack, with reduced overhead relative to PopValue – must be zero or one items left!

PopValue()

FPreshaderValue UE::Shader::FPreshaderStack::PopValue

(

)

Returned values are invalidated when anything is pushed onto the stack

PushEmptyValue() [1/2]

TArrayView< FValueComponent > UE::Shader::FPreshaderStack::PushEmptyValue

(

const FPreshaderType &

InType

)

PushEmptyValue() [2/2]

FValueComponent * UE::Shader::FPreshaderStack::PushEmptyValue	(	EValueType	InType,
		int32	NumComponents
	)

PushValue() [1/3]

void UE::Shader::FPreshaderStack::PushValue	(	const FPreshaderType &	InType,
		TArrayView< const FValueComponent >	InComponents
	)

PushValue() [2/3]

void UE::Shader::FPreshaderStack::PushValue

(

const FPreshaderValue &

InValue

)

PushValue() [3/3]

void UE::Shader::FPreshaderStack::PushValue
