Member Function Documentation

◆ data_size()

virtual unsigned int fastuidraw::PainterShaderData::data_size ( void ) const

pure virtual

To be implemented by a derived class to return the number of uvec4 blocks needed to pack the data.

Implemented in fastuidraw::PainterDashedStrokeParams, and fastuidraw::PainterStrokeParams.

◆ number_resources()

virtual unsigned int fastuidraw::PainterShaderData::number_resources ( void ) const

inlinevirtual

To be optionally implemented by a derived class to return the number of resources that need to be resident after packing. Default implementation returns 0.

Definition at line 85 of file painter_shader_data.hpp.

◆ pack_data()

virtual void fastuidraw::PainterShaderData::pack_data ( c_array< uvec4 > dst ) const

pure virtual

To be implemented by a derived class to pack the data.

Parameters

dst	location to which to pack the data

Implemented in fastuidraw::PainterDashedStrokeParams, and fastuidraw::PainterStrokeParams.

◆ save_resources()

virtual void fastuidraw::PainterShaderData::save_resources ( c_array< reference_counted_ptr< const resource_base > > dst ) const

inlinevirtual

To be optionally implemented by a derived class to save references to resources that need to be resident after packing. Default implementation does nothing.
