Detailed Description

template<typename T>
class Ocean::Identity< T >

This class implements a helper class allowing to define the identity data type of a given type.

The class can be used if e.g., to prevent that the compiler is able to implicitly determine a template data type in a function.

The following code example explains the usage of the helper class:

template <typename T>
void functionA(T value)
{
    // do something
}
 
template <typename T>
void functionB(typename Identity<T>::Type value)
{
    // do something
}
 
void main()
{
    functionA(1); // will compile
 
    functionB(1); // will not compile, e.g., with error message 'void Ocean::functionB(Identity<T>::Type)': could not deduce template argument for 'T'
 
    functionB<double>(1); // will compile
}

Template Parameters

T	The data type to be used
