ConfigParser (Helidon Project 2.0.0-RC2 API)

All Known Implementing Classes:

HoconConfigParser, PropertiesConfigParser, YamlConfigParser
```
public interface ConfigParser
```
Transforms config ConfigParser.Content into a ConfigNode.ObjectNode that represents the original structure and values from the content.
The application can register parsers on a Builder using the Config.Builder.addParser(ConfigParser) method. The config system also locates parsers using the Java ServiceLoader mechanism and automatically adds them to every Builder unless the application disables this feature for a given Builder by invoking Config.Builder.disableParserServices().
A parser can specify a Priority. If no priority is explicitly assigned, the value of 100 is assumed.
Parser is used by the config system and a config source provides data as an input stream.

Config.Builder.addParser(ConfigParser), ParsableSource, ConfigParsers - access built-in implementations.

Modifier and Type	Method	Description

static final int PRIORITY

    Default priority of the parser if registered by Config.Builder automatically.

```
Set<String> supportedMediaTypes()
```
    Returns set of supported media types by the parser.
    Set of supported media types is used when config system looks for appropriate parser based on media type of content.
    ParsableSource implementations can use MediaTypes to probe for media type of content to provide it to config system through ConfigParser.Content.Builder.mediaType(String).
    
    Returns:
    
    supported media types by the parser
  - parse
```
ConfigNode.ObjectNode parse(ConfigParser.Content content)
                     throws ConfigParserException
```
    Parses a specified ConfigContent into a hierarchical configuration representation.
    Never returns null.
    
    Parameters:
    
    content - a content to be parsed
    
    Returns:
    
    parsed hierarchical configuration representation
    
    Throws:
    
    ConfigParserException - in case of problem to parse configuration from the source
