Member Function Documentation

◆ bitWidth()

int SkSL::MatrixType::bitWidth ( ) const
inlineoverridevirtual

Reimplemented from SkSL::Type.

Definition at line 468 of file SkSLType.cpp.

468 {
469 return this->componentType().bitWidth();
470 }
int bitWidth() const override
Definition: SkSLType.cpp:341

◆ columns()

int SkSL::MatrixType::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 460 of file SkSLType.cpp.

460 {
461 return fColumns;
462 }

◆ componentType()

const ScalarType & SkSL::MatrixType::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 456 of file SkSLType.cpp.

456 {
457 return fComponentType;
458 }

◆ isAllowedInES2()

bool SkSL::MatrixType::isAllowedInES2 ( ) const
inlineoverridevirtual

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

Reimplemented from SkSL::Type.

Definition at line 476 of file SkSLType.cpp.

476 {
477 return fColumns == fRows;
478 }

◆ isMatrix()

bool SkSL::MatrixType::isMatrix ( ) const
inlineoverridevirtual

Reimplemented from SkSL::Type.

Definition at line 472 of file SkSLType.cpp.

472 {
473 return true;
474 }

◆ rows()

int SkSL::MatrixType::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 464 of file SkSLType.cpp.

464 {
465 return fRows;
466 }

◆ slotCount()

size_t SkSL::MatrixType::slotCount ( ) const
inlineoverridevirtual

Returns the number of scalars needed to hold this type.

Reimplemented from SkSL::Type.

Definition at line 480 of file SkSLType.cpp.

480 {
481 return fColumns * fRows;
482 }

◆ slotType()

const Type & SkSL::MatrixType::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 484 of file SkSLType.cpp.

484 {
485 SkASSERT(n < this->slotCount());
486 return fComponentType;
487 }
size_t slotCount() const override
