Detailed Description

Overloaded stream operators.

Provides stream operators for all classes that define a const_iterator type, such as STL containers.

To bring the operators defined in TextStream in the current scope, simply use:

using TextStream::operator<<;

If the preprocessor macro TEXTSTREAM_DISPLAY_COUNT is defined, the number of elements printed to the stream is appended to the output. For example, without defining that macro, the following code:

using TextStream::operator<<;
std::cout << std::vector<int>{1, 2, 3, 4, 5} << std::endl;

outputs:

[1, 2, 3, 4, 5]

whereas it ouputs:

[1, 2, 3, 4, 5]/5

when TEXTSTREAM_DISPLAY_COUNT is defined (before including TextStream.h).

Function Documentation

operator<<()

template<typename T >

std::enable_if< detail::has_const_iterator< T >::value and !detail::is_ostreamable< T >::value, std::ostream & >::type LatBuilder::TextStream::operator<<	(	std::ostream &	os,
		const T &	x
	)

Overload of the output stream operator for sequences.

This operator can be applied an instance of a class that defines a const_iterator type, assuming that the members begin() and end() are also defined. If the class defines a key_type type, curly brackets are used as delimitors; otherwise, square brackets are used.
