AbstractParsableConfigSource (Helidon 1.4.12 API)

java.lang.Object
- io.helidon.config.spi.AbstractSource<ConfigNode.ObjectNode,S>
- - io.helidon.config.spi.AbstractConfigSource<S>
  - - io.helidon.config.spi.AbstractParsableConfigSource<S>

Type Parameters:

S - a type of data stamp

All Implemented Interfaces:

Changeable<ConfigNode.ObjectNode>, ConfigSource, Source<ConfigNode.ObjectNode>, AutoCloseable, Supplier<ConfigSource>

Direct Known Subclasses:

EtcdConfigSource, GitConfigSource
```
public abstract class AbstractParsableConfigSource<S>
extends AbstractConfigSource<S>
```
Abstract implementation of ConfigSource that uses a ConfigParser to parse configuration content accessible as a Readable.
Typically concrete implementations will extend this class in order to delegate to ConfigParser the loading of configuration content into an ConfigNode.ObjectNode representing the hierarchical structure of the configuration.
