ConfigOrigin

org.ekrich.config.ConfigOrigin
trait ConfigOrigin

Represents the origin (such as filename and line number) of a ConfigValue for use in error messages. Obtain the origin of a value with ConfigValue#origin. Exceptions may have an origin, see ConfigException#origin, but be careful because ConfigException.origin() may return null.

It's best to use this interface only for debugging; its accuracy is "best effort" rather than guaranteed, and a potentially-noticeable amount of memory could probably be saved if origins were not kept around, so in the future there might be some option to discard origins.

Do not implement this interface; it should only be implemented by the config library. Arbitrary implementations will not work because the library internals assume a specific concrete implementation. Also, this interface is likely to grow new methods over time, so third-party implementations will break.

def withComments(comments: List[String]): ConfigOrigin

Returns a ConfigOrigin based on this one, but with the given comments. Does not modify this instance or any ConfigValues with this origin (since they are immutable). To set the returned origin to a ConfigValue, use ConfigValue#withOrigin.

Returns a ConfigOrigin based on this one, but with the given comments. Does not modify this instance or any ConfigValues with this origin (since they are immutable). To set the returned origin to a ConfigValue, use ConfigValue#withOrigin.

Note that when the given comments are equal to the comments on this object, a new instance may not be created and this is returned directly.

Value parameters

comments

the comments used on the returned origin

Attributes

Returns

the ConfigOrigin with the given comments

def withLineNumber(lineNumber: Int): ConfigOrigin
