Header file for the FalseType type/value trait base class.
Compile time check whether the given type is a vector evaluation expression template.This type trait class tests whether or not the given type Type is a vector evaluation expression template. In order to qualify as a valid vector evaluation expression template, the given type has to derive (publicly or privately) from the VecEvalExpr base class. In case the given type is a valid vector evaluation expression template, the value member enumeration is set to 1, the nested type definition Type is TrueType, and the class derives from TrueType. Otherwise value is set to 0, Type is FalseType, and the class derives from FalseType.
