Detailed Description

template<typename NTYPE>
class pni::core::binary_t< NTYPE >

This class represents a binary data type. Typically binary data is represented by a typedef to an unsigned char type. However, this has an inconvenience: the unsigned char and the typedef for binary are indistinguishable by the compiler. Thus, such a binary type cannot be used for function overloading or for template specialization - it would always be treated by the compiler as the underlying unsigned char type.

To circumvent this problem libpnicore defines this binary type which can be used instead of a simple typedef to unsigned char. The BinaryType template has several advantages:

• it can be distinguished from the type used to store binary data
• all arithmetic operators are stripped from the type.

Thus this type cannot be used for arithmetic operations directly. Its primary purpose is to hold uninterpreted binary data for transfer. However it can be converted to the native type used to hold the data. Stream operators are provided for IO operations using binary data.

Template Parameters

NTYPE

native type used to store binary data
