    Baggage with no entries.
  - builder
```
static Baggage.Builder builder()
```
    Creates a new Baggage.Builder for creating Baggage.
  - current
```
static Baggage current()
```
    Returns Baggage from the current Context, falling back to empty Baggage if none is in the current Context.
  - fromContext
```
static Baggage fromContext(io.opentelemetry.context.Context context)
```
    Returns the Baggage from the specified Context, falling back to a empty Baggage if there is no baggage in the context.
  - fromContextOrNull
```
@Nullable
static Baggage fromContextOrNull(io.opentelemetry.context.Context context)
```
    Returns the Baggage from the specified Context, or null if there is no baggage in the context.
  - storeInContext
```
default io.opentelemetry.context.Context storeInContext(io.opentelemetry.context.Context context)
```
    Specified by:
    
    storeInContext in interface io.opentelemetry.context.ImplicitContextKeyed
  - size
```
int size()
```
    Returns the number of entries in this Baggage.
  - isEmpty
```
default boolean isEmpty()
```
    Returns whether this Baggage is empty, containing no entries.
  - forEach
```
void forEach(BaggageConsumer consumer)
```
    Iterates over all the entries in this Baggage.
  - getEntryValue
```
@Nullable
String getEntryValue(String entryKey)
```
    Returns the String value associated with the given key, without metadata.
    
    Parameters:
    
    entryKey - entry key to return the value for.
    
    Returns:
    
    the value associated with the given key, or null if no Entry with the given entryKey is in this Baggage.
  - toBuilder
```
Baggage.Builder toBuilder()
```
    Create a Builder pre-initialized with the contents of this Baggage. The returned Builder will be set to not use an implicit parent, so any parent assignment must be done manually.
