AMRange - basic operation with ranges and sets of rangesUseful for example for implementing variant types. You may have union of multiple types and tag with stored type.
Usage
Range oprations
AMRange<int> r1(1,5);
AMRange<int> r2(1,5);
EXPECT_EQ(r1, r2);
r1 = r2;
EXPECT_EQ(r1, r2);
AMRange<int> ri1(1,8);
AMRange<int> ri2(5, 12);
AMRange<int> ri3 = ri1;
ri3.intersect(ri2);
EXPECT_EQ(ri3, AMRange<int>(5,8));
EXPECT_TRUE(AMRange(2,2).empty());
EXPECT_FALSE(AMRange(4,9).empty());
EXPECT_TRUE(AMRange(-9,10).
valid());
EXPECT_FALSE(AMRange(0,-1).
valid());
EXPECT_TRUE(AMRange(-5,5).in(0));
EXPECT_FALSE(AMRange(-5,5).in(-6));
EXPECT_TRUE(AMRange(-5,5) < AMRange(0,10));
EXPECT_FALSE(AMRange(-5,5) < AMRange(-10,10));
AMRange rp1(1,5);
AMRange rp2(4,10);
AMRange rp3 = rp1;
rp3 += rp2;
EXPECT_EQ(rp3,AMRange(1,10));
AMRange rm1(1,5);
AMRange rm2(4,10);
AMRange rm3 = rp1;
rp3 -= rp2;
EXPECT_EQ(rp3,AMRange(1,4));
Set of ranges
std::set<AMRange<int> > s01;
std::set<AMRange<int> > s05 = {AMRange(1,5), AMRange(3, 9)};
std::set<AMRange<int> > s07 = {AMRange(1,5), AMRange(7, 9), AMRange(7, 12), AMRange(12, 15), AMRange(17, 19)};
std::set<AMRange<int> > s11 = {AMRange(1, 15), AMRange(17, 19)};
std::set<AMRange<int> > s13 = {AMRange(9, 15), AMRange(17, 19)};
EXPECT_EQ(
pack(s01), s01);
EXPECT_EQ(
pack(s05), std::set<AMRange<int> >{AMRange(1, 9)});
EXPECT_EQ(s07 + s05, s11);
EXPECT_EQ(s07 - s05, s13);;
