Base type for affine expression.
AffineExpr's are immutable value types with intuitive operators to operate on chainable, lightweight compositions. An AffineExpr is an interface to the underlying storage type pointer.

AffineExpr AffineExpr::compose | ( | AffineMap | map | ) | const |
Compose with an AffineMap.
Returns the composition of this AffineExpr with map
.
Prerequisites: this
and map
are composable, i.e. that the number of AffineDimExpr of this
is smaller than the number of results of map
. If a result of a map does not have a corresponding AffineDimExpr, that result simply does not appear in the produced AffineExpr.
Example: expr: d0 + d2
map: (d0, d1, d2)[s0, s1] -> (d0 + s1, d1 + s0, d0 + d1 + d2)
returned expr: d0 * 2 + d1 + d2 + s1
