JacksonFeatureSet (jackson-core 2.16.0)

java.lang.Object
- com.fasterxml.jackson.core.util.JacksonFeatureSet<F>

All Implemented Interfaces:

Serializable
```
public final class JacksonFeatureSet<F extends JacksonFeature>
extends Object
implements Serializable
```
Container similar to EnumSet meant for storing sets of JacksonFeatures (usually Enums): main difference being that these sets are immutable. Also only supports relatively small sets of features: specifically, up to 31 features.

Since:

2.12

protected JacksonFeatureSet(int bitmask)
```
    Constructor for creating instance with specific bitmask, wherein 1 bit means matching JacksonFeature is enabled and 0 disabled.
    
    Parameters:
    
    bitmask - Bitmask for features that are enabled
- Method Detail
  - fromDefaults
```
public static <F extends JacksonFeature> JacksonFeatureSet<F> fromDefaults(F[] allFeatures)
```
    "Default" factory which will calculate settings based on default-enabled status of all features.
    
    Type Parameters:
    
    F - Self-reference type for convenience
    
    Parameters:
    
    allFeatures - Set of all features (enabled or disabled): usually from Enum.values()
    
    Returns:
    
    Feature set instance constructed
  - fromBitmask
```
public static <F extends JacksonFeature> JacksonFeatureSet<F> fromBitmask(int bitmask)
```
  - with
```
public JacksonFeatureSet<F> with(F feature)
```
    Mutant factory for getting a set in which specified feature is enabled: will either return this instance (if no change), or newly created set (if there is change).
    
    Parameters:
    
    feature - Feature to enable in set returned
    
    Returns:
    
    Newly created set of state of feature changed; this if not
  - without
```
public JacksonFeatureSet<F> without(F feature)
```
    Mutant factory for getting a set in which specified feature is disabled: will either return this instance (if no change), or newly created set (if there is change).
    
    Parameters:
    
    feature - Feature to disable in set returned
    
    Returns:
    
    Newly created set of state of feature changed; this if not
  - isEnabled
```
public boolean isEnabled(F feature)
```
    Main accessor for checking whether given feature is enabled in this feature set.
    
    Parameters:
    
    feature - Feature to check
    
    Returns:
    
    True if feature is enabled in this set; false otherwise
  - asBitmask
```
public int asBitmask()
```
    Accessor for underlying bitmask
    
    Returns:
    
    Bitmask of enabled features
