/** @brief Template "trait" class for OpenCV primitive data types.
@note Deprecated. This is replaced by "single purpose" traits: traits::Type and traits::Depth
A primitive OpenCV data type is one of unsigned char, bool, signed char, unsigned short, signed
short, int, float, double, or a tuple of values of one of these types, where all the values in the
tuple have the same type. Any primitive type from the list can be defined by an identifier in the
@ -102,10 +106,13 @@ So, such traits are used to tell OpenCV which data type you are working with, ev
not native to OpenCV. For example, the matrix B initialization above is compiled because OpenCV
defines the proper specialized template class DataType\<complex\<_Tp\> \> . This mechanism is also
useful (and used in OpenCV this way) for generic algorithms implementations.
@note Default values were dropped to stop confusing developers about using of unsupported types (see #7599)
