All Implemented Interfaces:

ConfigParser

@Priority(200)
public class PropertiesConfigParser
extends Object
implements ConfigParser

ConfigParser implementation that parses Java Properties content.

The parser implementation supports ServiceLoader, i.e. Config.Builder can automatically load and register PropertiesConfigParser instance, if not disabled. And of course it can be registered programmatically.

Priority of the PropertiesConfigParser to be used by Config.Builder, if loaded automatically as a service, is 200.

supportedMediaTypes

public Set<String> supportedMediaTypes()

Description copied from interface: ConfigParser

Returns set of supported media types by the parser.

ParsableSource implementations can use MediaTypes to probe for media type of content to provide it to config system through ConfigParser.Content.Builder.mediaType(String).

Specified by:

supportedMediaTypes in interface ConfigParser

Returns:

supported media types by the parser

parse

public ConfigNode.ObjectNode parse(ConfigParser.Content content)
                            throws ConfigParserException
