FileSystemConfigSource (SmallRye Config: ConfigSource - FileSystem 3.3.4 API)

java.lang.Object
- io.smallrye.config.common.AbstractConfigSource
- - io.smallrye.config.common.MapBackedConfigSource
  - - io.smallrye.config.source.file.FileSystemConfigSource

All Implemented Interfaces:

Serializable, org.eclipse.microprofile.config.spi.ConfigSource
```
public class FileSystemConfigSource
extends MapBackedConfigSource
```
Read configuration from a file directory.
Each file in the directory corresponds to a property where the file name is the property key and the file textual content is the property value.
For example, if a directory structure looks like:
```
 
 foo/
 ├── num.max
 └── num.size
 
 
```
new FileSystemConfigSource(new File("foo"), 100) will provide 2 properties:
- num.max
- num.size
Nested directories are not supported.
