Member Function Documentation

◆ fields()

SkSpan< const Field > SkSL::StructType::fields ( ) const

inlineoverridevirtual

Reimplemented from SkSL::Type.

Definition at line 624 of file SkSLType.cpp.

                                                {
        return fFields;
    }

◆ isAllowedInES2()

bool SkSL::StructType::isAllowedInES2 ( ) const

inlineoverridevirtual

Returns true if this type is legal to use in a strict-ES2 program.

Reimplemented from SkSL::Type.

Definition at line 640 of file SkSLType.cpp.

                                         {
        return fIsAllowedInES2;
    }

◆ isAllowedInUniform()

bool SkSL::StructType::isAllowedInUniform ( Position * errorPosition ) const

inlineoverridevirtual

Returns true if this type is legal to use as a uniform. If false is returned, the errorPosition field may be populated; if it is, this position can be used to emit an extra diagnostic "caused by: <a field>" for nested types. Note that runtime effects enforce additional, much stricter rules about uniforms; these limitations are not handled here.

Reimplemented from SkSL::Type.

Definition at line 644 of file SkSLType.cpp.

                                                                    {
        if (errorPosition != nullptr) {
            *errorPosition = fUniformErrorPosition;
        }
        return !fUniformErrorPosition.valid();
    }

◆ isBuiltin()

bool SkSL::StructType::isBuiltin ( ) const

inlineoverridevirtual

Returns true if this type is known to come from BuiltinTypes, or is declared in a module. If this returns true, the Type will always be available in the root SymbolTable and never needs to be copied to migrate an Expression from one location to another. If it returns false, the Type might not exist in a separate SymbolTable and you'll need to consider cloning it.

Reimplemented from SkSL::Type.

Definition at line 636 of file SkSLType.cpp.

◆ slotType()

const Type & SkSL::StructType::slotType ( size_t ) const

inlineoverridevirtual

Returns the type of the value in the nth slot. For scalar, vector and matrix types, should always match componentType().

Reimplemented from SkSL::Type.

Definition at line 672 of file SkSLType.cpp.

                                                  {
