Detailed Description

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.

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)
