public class BambooObjectUtils extends Object

  • Method Details

    • compare

      @Deprecated public static <T extends Comparable<T>> int compare(@Nullable T lhs, @Nullable T rhs)
      Deprecated.
      since 5.10, use ObjectUtils.compare(Comparable, Comparable)
      Compares two objects in a null-safe way. A null object is considered to be lesser than a non-null one

    • getId

      public static String getId(@Nullable @Nullable Object o)

    • rethrowAnyCauseThatIsInstanceOf

      public static <T extends Throwable, C extends T> RuntimeException rethrowAnyCauseThatIsInstanceOf(@NotNull T t, Class<C> toRethrowC) throws C
      Given a Throwable t, and a Throwable toRethrowC, if t is an instance of toRethrowC, it will be returned. Otherwise it will recursively look into chain of causes of Throwable t. If one of them is an instance of RethrowC, it will be returned. Otherwise, it will throw RuntimeException or, if it's already a RuntimeException, throw it directly. This method should be used when a method has a broad throws clause (e.g. Callable) and we know which checked exceptions it will return throwable of class toRethrowC or throw runtime exception.
      Throws:
      C extends T

    • getMessageOrStackTrace

      @NotNull public static @NotNull String getMessageOrStackTrace(@NotNull @NotNull Throwable throwable)
      Returns:
      a message from throwable, or, if there's no message create one using exception class name and stack trace

    • asRuntimeException

      public static <T extends Throwable> RuntimeException asRuntimeException(T t)

    • toString

      public static String toString(Object key)

    • getCached

      public static <T> T getCached(@NotNull @NotNull AtomicReference<T> valueHolder, @NotNull @NotNull Supplier<T> valueSupplier)

      Obtain a value from the given supplier, caching it in the passed holder variable. The supplier will be only executed once, and the calculated result will be cached in the holder variable for future calls to avoid unnecessary calculations.

      This method uses synchronization by intrinsic locking on the value holder param.

      Example usage: 

      
 class MyClass {
     private final AtomicReference<User> currentUser = new AtomicReference<>();
     ...
     public User getCurrentUser() {
         return getCached(currentUser, () -> userManager.getUser(authenticationContext.getCurrentUserName()));
     }
 }
      Type Parameters:
      T - type of returned value
      Parameters:
      valueHolder - a variable to cache the result of calling the supplier
      valueSupplier - supplier of the value to be called once only
      Returns:
      value returned by supplier or obtained from cache if it was already defined; if the value is stored in the cache, supplier will not be called.
      Throws:
      NullPointerException - if the supplier returns a null value
