Member Function Documentation

◆ bitWidth()

int SkSL::LiteralType::bitWidth ( ) const

inlineoverridevirtual

Reimplemented from SkSL::Type.

Definition at line 285 of file SkSLType.cpp.

                                  {
        return fScalarType.bitWidth();
    }

◆ columns()

int SkSL::LiteralType::columns ( ) const

inlineoverridevirtual

For matrices and vectors, returns the number of columns (e.g. both mat3 and float3 return 3). For scalars, returns 1. For arrays, returns either the size of the array (if known) or -1. For all other types, causes an assertion failure.

Reimplemented from SkSL::Type.

Definition at line 273 of file SkSLType.cpp.

                                 {
        return 1;
    }

◆ isLiteral()

bool SkSL::LiteralType::isLiteral ( ) const

inlineoverridevirtual

Reimplemented from SkSL::Type.

Definition at line 301 of file SkSLType.cpp.

                                    {
        return true;
    }

◆ isScalar()

bool SkSL::LiteralType::isScalar ( ) const

Reimplemented from SkSL::Type.

Definition at line 297 of file SkSLType.cpp.

                                   {

        return fScalarType.maximumValue();
    }

◆ minimumValue()

double SkSL::LiteralType::minimumValue ( ) const

inlineoverridevirtual

Returns the minimum value that can fit in the type.

Reimplemented from SkSL::Type.

Definition at line 289 of file SkSLType.cpp.

                                         {
        return fScalarType.minimumValue();
    }

◆ numberKind()

NumberKind SkSL::LiteralType::numberKind ( ) const

inlineoverridevirtual

Returns the NumberKind of this type (always kNonnumeric for non-scalar values).

Reimplemented from SkSL::Type.

Definition at line 281 of file SkSLType.cpp.

                                           {
        return fScalarType.numberKind();
    }

◆ priority()

int SkSL::LiteralType::priority ( ) const

inlineoverridevirtual

Returns the "priority" of a number type, in order of float > half > int > short. When operating on two number types, the result is the higher-priority type.

Reimplemented from SkSL::Type.

Definition at line 269 of file SkSLType.cpp.

                                  {
        return fPriority;
    }

◆ rows()

int SkSL::LiteralType::rows ( ) const

inlineoverridevirtual

For matrices, returns the number of rows (e.g. mat2x4 returns 4). For vectors and scalars, returns 1. For all other types, causes an assertion failure.

Reimplemented from SkSL::Type.

Definition at line 277 of file SkSLType.cpp.

                              {
        return 1;
    }

◆ scalarTypeForLiteral()

const Type & SkSL::LiteralType::scalarTypeForLiteral ( ) const

inlineoverridevirtual

Reimplemented from SkSL::Type.

Definition at line 265 of file SkSLType.cpp.

        return fScalarType;
    }

◆ slotCount()

size_t SkSL::LiteralType::slotCount ( ) const

inlineoverridevirtual

Returns the number of scalars needed to hold this type.

Reimplemented from SkSL::Type.

Definition at line 305 of file SkSLType.cpp.

                                      {
        return 1;
    }

◆ slotType()

const Type & SkSL::LiteralType::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 309 of file SkSLType.cpp.

                                                  {
