Member Function Documentation

◆ bitWidth()

int SkSL::VectorType::bitWidth ( ) const

inlineoverridevirtual

Reimplemented from SkSL::Type.

Definition at line 724 of file SkSLType.cpp.

                                  {
        return this->componentType().bitWidth();
    }

◆ columns()

int SkSL::VectorType::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 716 of file SkSLType.cpp.

                                 {
        return fColumns;
    }

◆ componentType()

const ScalarType & SkSL::VectorType::componentType ( ) const

inlineoverridevirtual

For matrices and vectors, returns the type of individual cells (e.g. mat2 has a component type of Float). For arrays, returns the base type. For all other types, returns the type itself.

Reimplemented from SkSL::Type.

Definition at line 712 of file SkSLType.cpp.

                                                     {
        return fComponentType;
    }

◆ isAllowedInES2()

bool SkSL::VectorType::isAllowedInES2 ( ) const

inlineoverridevirtual

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

Reimplemented from SkSL::Type.

Definition at line 732 of file SkSLType.cpp.

                                         {
        return fComponentType.isAllowedInES2();
    }

◆ isAllowedInUniform()

bool SkSL::VectorType::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 736 of file SkSLType.cpp.

                                                                    {
        return fComponentType.isAllowedInUniform(errorPosition);
    }

◆ isVector()

bool SkSL::VectorType::isVector ( ) const

inlineoverridevirtual

Reimplemented from SkSL::Type.

Definition at line 728 of file SkSLType.cpp.

                                   {
        return true;
    }

◆ rows()

int SkSL::VectorType::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 720 of file SkSLType.cpp.

                              {
        return 1;
    }

◆ slotCount()

size_t SkSL::VectorType::slotCount ( ) const

inlineoverridevirtual

Returns the number of scalars needed to hold this type.

Reimplemented from SkSL::Type.

Definition at line 740 of file SkSLType.cpp.

                                      {
        return fColumns;
    }

◆ slotType()

const Type & SkSL::VectorType::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 744 of file SkSLType.cpp.

                                                  {
        SkASSERT(n < SkToSizeT(fColumns));
        return fComponentType;
    }
