public class Setting<T>
extends ToXContentToBytes
```
A setting. Encapsulates typical stuff like default value, parsing, and scope. Some (SettingsProperty.Dynamic) can by modified at run time using the API. All settings inside elasticsearch or in any of the plugins should use this type-safe and generic settings infrastructure together with AbstractScopedSettings. This class contains several utility methods that makes it straight forward to add settings for the majority of the cases. For instance a simple boolean settings can be defined like this:
```
 public static final Setting<Boolean>; MY_BOOLEAN = Setting.boolSetting("my.bool.setting", true, SettingsProperty.NodeScope);
 
```
To retrieve the value of the setting a Settings object can be passed directly to the get(Settings) method.
```
 final boolean myBooleanValue = MY_BOOLEAN.get(settings);
 
```
It's recommended to use typed settings rather than string based settings. For example adding a setting for an enum type:
```
 public enum Color {
     RED, GREEN, BLUE;
 }
 public static final Setting<Color> MY_BOOLEAN =
     new Setting<>("my.color.setting", Color.RED.toString(), Color::valueOf, SettingsProperty.NodeScope);
 
 
```

Method Detail

getKey
```
public final java.lang.String getKey()
```
Returns the settings key or a prefix if this setting is a group setting. Note: this method should not be used to retrieve a value from a Settings object. Use get(Settings) instead

See Also:

isGroupSetting()

getRawKey
```
public final Setting.Key getRawKey()
```
Returns the original representation of a setting key.

isDynamic
```
public final boolean isDynamic()
```
Returns true if this setting is dynamically updateable, otherwise false

isFinal
```
public final boolean isFinal()
```
Returns true if this setting is final, otherwise false

getProperties
```
public java.util.EnumSet<Setting.Property> getProperties()
```
Returns the setting properties

See Also:

Setting.Property

isFiltered
```
public boolean isFiltered()
```
Returns true if this setting must be filtered, otherwise false

hasNodeScope
```
public boolean hasNodeScope()
```
Returns true if this setting has a node scope, otherwise false

hasIndexScope
```
public boolean hasIndexScope()
```
Returns true if this setting has an index scope, otherwise false

isDeprecated
```
public boolean isDeprecated()
```
Returns true if this setting is deprecated, otherwise false

isShared
```
public boolean isShared()
```
Returns true if this setting is shared with more than one other module or plugin, otherwise false

getDefaultRaw
```
public java.lang.String getDefaultRaw(Settings settings)
```
Returns the default value string representation for this setting.

Parameters:

settings - a settings object for settings that has a default value depending on another setting if available

getDefault
```
public T getDefault(Settings settings)
```
Returns the default value for this setting.

Parameters:

settings - a settings object for settings that has a default value depending on another setting if available

exists
```
public boolean exists(Settings settings)
```
Returns true iff this setting is present in the given settings object. Otherwise false

get
```
public T get(Settings settings)
```
Returns the settings value. If the setting is not present in the given settings object the default value is returned instead.

diff
```
public void diff(Settings.Builder builder,
                 Settings source,
                 Settings defaultSettings)
```
Add this setting to the builder if it doesn't exists in the source settings. The value added to the builder is taken from the given default settings object.

Parameters:

builder - the settings builder to fill the diff into

source - the source settings object to diff

defaultSettings - the default settings object to diff against

getRaw
```
public java.lang.String getRaw(Settings settings)
```
Returns the raw (string) settings value. If the setting is not present in the given settings object the default value is returned instead. This is useful if the value can't be parsed due to an invalid value to access the actual value.

match
```
public final boolean match(java.lang.String toTest)
```
Returns true iff the given key matches the settings key or if this setting is a group setting if the given key is part of the settings group.

This setting type allows to validate settings that have the same type and a common prefix. For instance feature.${type}=[true|false] can easily be added with this setting. Yet, prefix key settings don't support updaters out of the box unless getConcreteSetting(String) is used to pull the updater.
