io.quarkus.deployment.pkg.steps.MethodKey

final class MethodKey
extends Object

Structured key for a JVM method, storing the three components provided by ASM's MethodVisitor.visitMethodInsn(int, java.lang.String, java.lang.String, java.lang.String) and ClassVisitor.visitMethod(int, java.lang.String, java.lang.String, java.lang.String, java.lang.String[]) without string concatenation.

The three strings (owner, name, descriptor) are interned by ASM's ClassReader from the class file constant pool, so storing them as references avoids all allocation. Hash code is lazily cached and computed from the three pre-cached String.hashCode() values.

Method Summary

Modifier and Type	Method	Description
boolean	equals(Object o)
int	hashCode()
(package private) boolean	isInitOrClinit()	Returns true if this method is a constructor (<init>) or static initializer (<clinit>).
(package private) static boolean	isJdkOrInfraClass(String nameOrKey)	Checks whether an internal class name (or method key starting with a class name) belongs to a JDK or infrastructure package that should be excluded from class-loading chain propagation.
(package private) static boolean	isSeedMethodOwner(String owner)	Returns true if the given method owner is one of the JDK classes that contain seed methods (ClassLoader, Class, or MethodHandles.Lookup).

SEED_METHOD_KEYS

static final Set<MethodKey> SEED_METHOD_KEYS

JDK methods that load classes by name — the seeds for call chain propagation.

Method Details

ownerAsDotName

String ownerAsDotName()

isInitOrClinit

boolean isInitOrClinit()

Returns true if this method is a constructor (<init>) or static initializer (<clinit>).

isSeedMethodOwner

static boolean isSeedMethodOwner(String owner)

Returns true if the given method owner is one of the JDK classes that contain seed methods (ClassLoader, Class, or MethodHandles.Lookup). Used during caller index construction to avoid creating MethodKey objects for JDK/infra calls that cannot possibly be seeds.

isJdkOrInfraClass

static boolean isJdkOrInfraClass(String nameOrKey)

Checks whether an internal class name (or method key starting with a class name) belongs to a JDK or infrastructure package that should be excluded from class-loading chain propagation. Works on both bare owner names (java/lang/Class) and full method keys (java/lang/Class.forName(...)) because the check is prefix-based.
