Detailed Description

template<typename Key, typename ElementLattice>
class clang::dataflow::MapLattice< Key, ElementLattice >

A lattice that maps keys to individual lattice elements.

When instantiated with an ElementLattice that is a bounded semi-lattice, MapLattice is itself a bounded semi-lattice, so long as the user limits themselves to a finite number of keys. In that case, top is (implicitly), the map containing all valid keys mapped to top of ElementLattice.

Requirements on ElementLattice:

• Provides standard declarations of a bounded semi-lattice.

If an entry exists in one map but not the other, the missing entry is treated as implicitly mapping to bottom.

So, the joined map contains the entry as it was in the source map.
