- Method Detail
  - get
```
String get(String key)
```
    Throws:
    
    RuntimeException - if key is null or empty. You may want to use Sources.checkKey(String) for implementations.
  - keySet
```
Collection<String> keySet()
```
    Returns all keys, for which get(String) does not return null. This operation is optional - if this source does not support this operation, it returns null. The result is always unmodifiable.
  - reload
```
default Properties.Source reload()
```
    Reloads the contents of this source from its origin, if this makes sense for the implementation. The reloaded contents are returned as a new source - this source is not modified.
    If the implementation does not support reloading, simply return this, which is also the default implementation.
  - getDescription
```
String getDescription()
```
