Detailed Description

template<typename ExprT, template< typename > class Op>
class Sacado::CacheFad::UnaryExpr< ExprT, Op >

Unary expression template.

This template class represents a unary operation of the form op(a) where a is the argument of type ExprT and op is the operation represented by type Op. The operation is evaluated by the non-static methods Op::computeValue() and Op::computeDx().

It is assumed Op::computeValue() will cache its result for later Op::computeDx() calls.

The documentation for this class was generated from the following file:
