Definition: DVecScalarDivExpr.h:108
Compile time check whether the given type is a multiplication expression template.This type trait class tests whether or not the given type Type is a multiplication expression template (i.e. an expression representing an element-wise vector multiplication, a matrix/vector multiplication, a vector/matrix multiplication, or a matrix multiplication). In order to qualify as a valid multiplication expression template, the given type has to derive (publicly or privately) from the MultExpr base class. In case the given type is a valid multiplication 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.
