Base template for the DeclIdTrait class.
The DeclIdTrait class template offers the possibility to select the resulting data type of a generic declid() operation on the given type MT. DeclIdTrait defines the nested type Type, which represents the resulting data type of the declid() operation. In case the given data type is not a dense or sparse matrix type, the resulting data type Type is set to INVALID_TYPE. Note that const and volatile qualifiers and reference modifiers are generally ignored.
Per default, the DeclIdTrait template only supports the following matrix types:
It is possible to specialize the DeclIdTrait template for additional user-defined matrix types. The following example shows the according specialization for the SymmetricMatrix class template:
The following example demonstrates the use of the DeclIdTrait template, where depending on the given matrix type the resulting type is selected:
