const ShEvalOpInfo * SH::ShEval::getEvalOpInfo (  ShOperation  op, ShValueType  dest, ShValueType  src0, ShValueType  src1 = SH_VALUETYPE_END, ShValueType  src2 = SH_VALUETYPE_END )  const

Returns a new op info representing the types that arguments should be cast into for an operation. Caches the result. Definition at line 113 of file ShEval.cpp. References SH::ShOperationInfo::arity, SH::ShCastManager::castDist(), SH::ShEvalOpInfo::encode(), SH::ShCastManager::instance(), SH::opInfo, and SH::shValueTypeName().

void SH::ShEval::operator() (  ShOperation  op, ShVariant *  dest, const ShVariant *  a, const ShVariant *  b, const ShVariant *  c )  const

Decides which evaluation evalOp to use and calls it up. If an op is unary, leave b, c = 0. If an op is binary leave c = 0. If an op has no dest, leave dest = 0. TODO (should really break this out into separate functions. EvalOps can have a single function in th einterface) Definition at line 32 of file ShEval.cpp. References SH::ShCastManager::doAllocCast(), SH::ShCastManager::doCast(), SH::ShVariant::encodeArray(), SH::ShVariantFactory::generate(), getEvalOpInfo(), SH::ShCastManager::instance(), SH::ShEvalOpInfo::m_dest, SH::ShEvalOpInfo::m_evalOp, SH::ShEvalOpInfo::m_src, SH::opInfo, SH::shValueTypeName(), SH::shVariantFactory(), SH::ShVariant::size(), SH::ShVariant::typeMatches(), and SH::ShVariant::valueType().
