Setting.Validator (server 7.1.0 API)

Type Parameters:

T - the type of the Setting

Enclosing class:

Setting<T>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public static interface Setting.Validator<T>
```
Represents a validator for a setting. The validate(Object) method is invoked early in the update setting process with the value of this setting for a fail-fast validation. Later on, the validate(Object, Map) method is invoked with the value of this setting and a map from the settings specified by settings()} to their values. All these values come from the same Settings instance.

Method Summary

- Method Detail
  - validate
```
void validate(T value)
```
    Validate this setting's value in isolation.
    
    Parameters:
    
    value - the value of this setting
  - validate
```
default void validate(T value,
                      java.util.Map<Setting<T>,T> settings)
```
    Validate this setting against its dependencies, specified by settings(). The default implementation does nothing, accepting any value as valid as long as it passes the validation in validate(Object).
    
    Parameters:
    
    value - the value of this setting
    
    settings - a map from the settings specified by settings()} to their values
  - settings
```
default java.util.Iterator<Setting<T>> settings()
```
    The settings on which the validity of this setting depends. The values of the specified settings are passed to validate(Object, Map). By default this returns an empty iterator, indicating that this setting does not depend on any other settings.
    
    Returns:
    
    the settings on which the validity of this setting depends.
