Base template for the MultTrait class.
The MultTrait class template offers the possibility to select the resulting data type of a generic multiplication operation between the two given types T1 and T2. MultTrait defines the nested type Type, which represents the resulting data type of the multiplication. In case the two types T1 and T2 cannot be multiplied, a compilation error is created. Note that const
and volatile
qualifiers and reference modifiers are generally ignored.
MultTrait is guaranteed to work for all built-in data types, complex numbers, all vector and matrix types of the Blaze library (including views and adaptors) and all data types that provide a multiplication operator (i.e. operator*
). In order to add support for user-defined data types that either don't provide a multiplication operator or whose multiplication operator returns a proxy object instead of a concrete type (as it is common in expression template libraries) it is possible to specialize the MultTrait template. The following example shows the according specialization for the multiplication between two dynamic column vectors:
The following example demonstrates the use of the MultTrait template, where depending on the two given data types the resulting data type is selected:
