Partition-backed implementations can override {@link #get} - * to return proxy types from pre-built partitions. + * Two method families correspond to two construction shapes: + *

    + *
  1. {@code compute*} — stub-then-initialize. The factory + * constructs a stub, registers it in the cache, then runs a + * {@link Consumer} that populates the stub via {@code unsafeSet}. + * Registering before the initializer runs is what makes recursive + * resolution during the initializer safe — reserved for types + * whose construction graph can recurse back to the same key: + *
      + *
    • {@link #computeClass} — Java's class graph is mutually + * recursive ({@code Foo extends Bar; Bar.field is Foo}).
      • + *
    • {@link #computeParameterized} — F-bounded polymorphism + * ({@code Comparable>}) and Kotlin + * parameterized self-refs.
      • + *
    • {@link #computeGenericTypeVariable} — type variable + * bounds can reference the variable itself + * ({@code >}).
      • + *
    2. + *
  2. {@code *For} — atomic build. The caller supplies a + * {@link Supplier} that returns a fully-constructed instance; the + * factory caches and returns it. No half-built object is ever + * observable through the cache. Used for variants without self-recursion + * on the same key: {@link #methodFor}, {@link #variableFor}, + * {@link #arrayFor}, {@link #intersectionFor}.
    3. + *
*

- * The construction surface is the {@code compute*} family. Each - * {@code computeXxx(signature, ..., initializer)} returns the cached instance - * if one already exists, otherwise allocates a stub, registers it in the cache - * before invoking the initializer, then runs the initializer to fill - * the stub's fields. Registering the stub up front is what makes recursive - * resolution during the initializer safe: a recursive lookup for the same - * signature finds the stub instead of looping. The initializer typically ends - * by calling {@code unsafeSet} on the stub to populate its fields. + * Parser code that needs a canonical identity-stable {@link JavaType.Class} + * for an FQN that has no Symbol/AST node (synthesized JVM facades, library + * placeholders, etc.) should call {@link #computeClass} with an empty + * initializer. There is no separate "lookup" surface — the absence of + * richer attribution is signaled at the call site by an empty initializer. + * + *

Key formats

+ * + * Two distinct keying schemes coexist; mixing them within one factory lifetime + * is a caller bug. + *
    + *
  • FQN keys — {@link #computeClass} is keyed on the + * fully-qualified name (e.g. {@code java.util.List}, + * {@code com.acme.Outer$Inner} for nested types). Universal across + * languages: every parser maps a {@link JavaType.Class} to its FQN the + * same way. The {@code fqn} value is exactly what + * {@link JavaType.FullyQualified#getFullyQualifiedName()} returns.
    • + *
  • Signature keys — every other {@code compute*} and + * {@code *For} method accepts an opaque {@code signature} string. The + * signature must uniquely identify the type within a single factory + * lifetime, and callers must obtain it from a + * {@link JavaTypeSignatureBuilder} consistent with the rest of the + * parser session. Different parsers produce different signature shapes + * (e.g. {@link JvmsTypeSignatureBuilder} for javac-driven Java parsing + * vs. per-language builders for Groovy/Kotlin/Scala/reflection); the + * factory does not inspect the format, but signatures from different + * builders are NOT interchangeable across one parser session's cache. + * The canonical reference shapes are documented on + * {@link JavaTypeSignatureBuilder}: e.g. methods + * {@code com.MyThing{name=add,return=void,parameters=[Integer]}}, + * variables {@code com.MyThing{name=MY_FIELD}}, generics + * {@code Generic{U extends java.lang.Comparable}}, parameterizeds + * {@code java.util.List>}, arrays + * {@code Integer[]}.
