PER_THREAD_SET

#define PER_THREAD_SET	(		pt,
			value
	)

Value:

    for (unsigned i = 0; i < pt.weight(); i++) { \
        pt.set_value(i, value); \
    }

PER_THREAD_POINTER_SET

#define PER_THREAD_POINTER_SET	(		pt,
			member,
			value
	)

Value:

    for (unsigned i = 0; i < pt.weight(); i++) { \
        pt.get_value(i)->member = value; \
    }

PER_THREAD_MEMBER_SET

#define PER_THREAD_MEMBER_SET	(		pt,
			member,
			value
	)

Value:

    for (unsigned i = 0; i < pt.weight(); i++) { \
        pt.get_value(i).member = value; \
    }

PER_THREAD_VECTOR_SET

#define PER_THREAD_VECTOR_SET	(		pt,
			member,
			value
	)

Value:

    for (unsigned i = 0; i < pt.weight(); i++) { \
        for (int j = 0; j < pt.get_value(i).size(); j++) \
            (pt.get_value(i))[j].member = value; \
    }

PER_THREAD_SUM

#define PER_THREAD_SUM	(		type,
			var,
			pt
	)

Value:

    type var = 0; \
    for (unsigned i = 0; i < pt.weight(); i++) { \
        var += pt.get_value(i); \
    }

PER_THREAD_POINTER_SUM

#define PER_THREAD_POINTER_SUM	(		type,
			var,
			pt,
			member
	)

Value:

    type var = 0; \
    for (unsigned i = 0; i < pt.weight(); i++) { \
        var += pt.get_value(i)->member; \
    }

PER_THREAD_MEMBER_SUM

#define PER_THREAD_MEMBER_SUM	(		type,
			var,
			pt,
			member
	)

Value:

    type var = 0; \
    for (unsigned i = 0; i < pt.weight(); i++) { \
        var += pt.get_value(i).member; \
    }

PER_THREAD_VECTOR_SUM

#define PER_THREAD_VECTOR_SUM	(		type,
			var,
			pt,
			index,
			member
	)

Value:

    type var = 0; \
    for (unsigned i = 0; i < pt.weight(); i++) { \
        var += pt.get_value(i)[index].member; \
    }
