@SuppressWarningsPrefix({"shrinkable","modifiability"})
public class ShrinkChecker
extends ModifiabilityBaseChecker

A type-checker that warns, at compile time, if a program might throw UnsupportedOperationException at run time due to calling a shrink method on a collection.

The checker enforces the Modifiability type system, where @Shrinkable collections can be safely mutated, @Unshrinkable collections cannot be shrunk, and @MaybeShrinkable collections have unknown shrink behavior.
