isOverride

public static boolean isOverride(@Nullable
                                 JavaType.Method method)

Determine if a method overrides a method from a superclass or interface.

Returns:

`true` if a superclass or implemented interface declares a non-private method with matching signature. `false` if a match is not found or the method, declaring type, or generic signature is null.

findOverriddenMethod

public static java.util.Optional<JavaType.Method> findOverriddenMethod(@Nullable
                                                                       JavaType.Method method)

Given a method type, searches the declaring type's parent and interfaces for a method with the same name and signature.

NOTE: This method will return an empty optional if the method, the method's declaring type, or the method's generic signature is null.

Returns:

An optional overridden method type declared in the parent.

findDeclaredMethod

public static java.util.Optional<JavaType.Method> findDeclaredMethod(@Nullable
                                                                     JavaType.FullyQualified clazz,
