Variables

  Type Name Description
Public variable bool bSerializeModifiedSource  
Public variable bool bSucceeded  
Public variable bool bSupportsQueryingUsedAttributes  
Public variable double CompileTime  
Public variable TArray< FShaderCompilerError > Errors  
Public variable FString ModifiedEntryPointName Use this field to store the entry point name if it's modified as part of the shader format's compilation process.
Public variable FString ModifiedShaderSource Use this field to store the shader source code if it's modified as part of the shader format's compilation process.
Public variable uint32 NumInstructions  
Public variable uint32 NumTextureSamplers  
Public variable FString OptionalFinalShaderSource This field should be set by backends which do not implement the independent preprocessing API to contain the "final" shader source as passed to the platform compiler.

Constructors

  Type Name Description
Public function    
Public function PRAGMA_DISABLE_DEPRECATION_WARNINGS Explicitly-defaulted copy/move ctors & assignment operators are needed temporarily due to deprecation of bFailedRemovingUnused/bUsedHLSLccCompiler fields.
Public function    

Functions

  Type Name Description
Public function void

CompressOutput ( FName ShaderCompressionFormat,
FOodleDataCompression::ECompressor OodleCompressor,
FOodleDataCompression::ECompressionLevel OodleLevel
)

 Calls GenerateOutputHash() before the compression, replaces FShaderCode with the compressed data (if compression result was smaller).
Public function void Generates OutputHash from the compiler output.
Public function void Add optional data in ShaderCode to perform additional shader input validation at runtime

Operators

  Type Name Description
Public function FShaderCompilerOutput &  
Public function FShaderCompilerOutput &  

Deprecated Variables

  Type Name Description
Public variable bool bFailedRemovingUnused bFailedRemovingUnused field is no longer used
Public variable bool bUsedHLSLccCompiler bUsedHLSLccCompiler field is no longer used
