Member Function Documentation

static std::list<std::string> SH::ShBackend::derived_targets (  const std::string &  target  )  [static]

Returns a list of targets derived from a generic target name. e.g. "arb:vertex, glsl:vertex" is returned when the generic target is "gpu:vertex". Referenced by SH::ShContext::bound_program(), and SH::ShProgramNode::is_compiled().

virtual std::string SH::ShBackend::name (  void   )  const [inline, virtual]

Short name of the backend (e.g. "arb", "cc", "glsl") Reimplemented in ShCc::CcBackend, shgl::ArbBackend, shgl::GlslBackend, and ShSm::Backend. Definition at line 105 of file ShBackend.hpp. Referenced by ~ShBackend().
