Constructor & Destructor Documentation

PainterItemShader() [1/3]

fastuidraw::PainterItemShader::PainterItemShader ( const reference_counted_ptr< PainterItemCoverageShader > &  cvg = reference_counted_ptr<PainterItemCoverageShader>() )

inlineexplicit

Ctor for a PainterItemShader with no sub-shaders.

Parameters

cvg	coverage shader for the PainterItemShader; the coverage shader, if present is to use the exact same PainterItemShaderData value but render to the coverage buffer. The PainterItemShader can then use those coverage values in its shader code.

Definition at line 51 of file painter_item_shader.hpp.

PainterItemShader() [2/3]

fastuidraw::PainterItemShader::PainterItemShader ( unsigned int  num_sub_shaders, const reference_counted_ptr< PainterItemCoverageShader > &  cvg = reference_counted_ptr<PainterItemCoverageShader>()  )

inlineexplicit

Ctor for creating a PainterItemShader which has multiple sub-shaders. The purpose of sub-shaders is for the case where multiple shaders almost same code and those code differences can be realized by examining a sub-shader ID.

Parameters

num_sub_shaders	number of sub-shaders
cvg	coverage shader for the PainterItemShader; the coverage shader, if present is to use the exact same PainterItemShaderData value but render to the coverage buffer. The PainterItemShader can then use those coverage values in its shader code.

Definition at line 72 of file painter_item_shader.hpp.

PainterItemShader() [3/3]

fastuidraw::PainterItemShader::PainterItemShader ( reference_counted_ptr< PainterItemShader >  parent, unsigned int  sub_shader, const reference_counted_ptr< PainterItemCoverageShader > &  cvg = reference_counted_ptr<PainterItemCoverageShader>()  )

inline

Ctor to create a PainterItemShader realized as a sub-shader of an existing PainterItemShader

Parameters

parent	parent PainterItemShader that has sub-shaders
sub_shader	which sub-shader of the parent PainterItemShader
cvg	coverage shader for the PainterItemShader; the coverage shader, if present is to use the exact same PainterItemShaderData value but render to the coverage buffer. The PainterItemShader can then use those coverage values in its shader code.

Definition at line 91 of file painter_item_shader.hpp.

Member Function Documentation

coverage_shader()

const reference_counted_ptr<PainterItemCoverageShader>& fastuidraw::PainterItemShader::coverage_shader ( void  ) const

inline

The coverage shader used by this PainterItemShader; the coverage shader, if present is to use the exact same PainterItemShaderData value but renders to the coverage buffer. The PainterItemShader can then use those coverage values in its shader code.
