Class ArrayBasedContext

java.lang.Object
io.opentelemetry.context.ArrayBasedContext
All Implemented Interfaces:
Context
final class ArrayBasedContext extends Object implements Context

  • Field Details

    • ROOT

      private static final Context ROOT

    • entries

      private final Object[] entries

  • Constructor Details

    • ArrayBasedContext

      private ArrayBasedContext(Object[] entries)

  • Method Details

    • root

      static Context root()

    • get

      @Nullable public <V> V get(ContextKey<V> key)
      Description copied from interface: Context
      Returns the value stored in this Context for the given ContextKey, or null if there is no value for the key in this context.
      Specified by:
      get in interface Context

    • with

      public <V> Context with(ContextKey<V> key, V value)
      Description copied from interface: Context
      Returns a new context with the given key value set. 
      Context withCredential = Context.current().with(CRED_KEY, cred);
withCredential.wrap(new Runnable() {
  public void run() {
     readUserRecords(userId, CRED_KEY.get());
  }
}).run();

      Note that multiple calls to Context.with(ContextKey, Object) can be chained together. 

      context.with(K1, V1).with(K2, V2);

      Nonetheless, Context should not be treated like a general purpose map with a large number of keys and values — combine multiple related items together into a single key instead of separating them. But if the items are unrelated, have separate keys for them.
