Member Function Documentation

◆ bitWidth()

int SkSL::ScalarType::bitWidth ( ) const

inlineoverridevirtual

Reimplemented from SkSL::Type.

Definition at line 341 of file SkSLType.cpp.

                                  {
        return fBitWidth;
    }

◆ columns()

int SkSL::ScalarType::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 345 of file SkSLType.cpp.

                                 {
        return 1;
    }

◆ isAllowedInES2()

bool SkSL::ScalarType::isAllowedInES2 ( ) const

inlineoverridevirtual

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

Reimplemented from SkSL::Type.

Definition at line 357 of file SkSLType.cpp.

                                         {
        return fNumberKind != NumberKind::kUnsigned;
    }

◆ isAllowedInUniform()

bool SkSL::ScalarType::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 361 of file SkSLType.cpp.

                                                      {

◆ rows()

int SkSL::ScalarType::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.

Definition at line 349 of file SkSLType.cpp.

                              {
