Constructor & Destructor Documentation

GrGLSLXPFragmentBuilder()

GrGLSLXPFragmentBuilder::GrGLSLXPFragmentBuilder ( )

inline

Appease the compiler; the derived class initializes GrGLSLShaderBuilder.

Definition at line 67 of file GrGLSLFragmentShaderBuilder.h.

: GrGLSLShaderBuilder(nullptr) {}

Member Function Documentation

dstColor()

virtual const char * GrGLSLXPFragmentBuilder::dstColor ( )

pure virtual

Returns the variable name that holds the color of the destination pixel. This may be nullptr if no effect advertised that it will read the destination.

Implemented in GrGLSLFragmentShaderBuilder.

enableAdvancedBlendEquationIfNeeded()

virtual void GrGLSLXPFragmentBuilder::enableAdvancedBlendEquationIfNeeded ( skgpu::BlendEquation  )

pure virtual

Adds any necessary layout qualifiers in order to legalize the supplied blend equation with this shader. It is only legal to call this method with an advanced blend equation, and only if these equations are supported.

Implemented in GrGLSLFragmentShaderBuilder.

hasSecondaryOutput()

virtual bool GrGLSLXPFragmentBuilder::hasSecondaryOutput ( ) const

pure virtual

Implemented in GrGLSLFragmentShaderBuilder.
