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.
Value members
Abstract methods
Returns any comments that appeared to "go with" this place in the file. Often an empty list, but never null. The details of this are subject to change, but at the moment comments that are immediately before an array element or object field, with no blank line after the comment, "go with" that element or field.

- Returns:
any comments that seemed to "go with" this origin, empty list if none
Returns a string describing the origin of a value or exception. This will never return null.
Returns a string describing the origin of a value or exception. This will never return null.
- Returns:
string describing the origin
Returns a filename describing the origin. This will return null if the origin was not a file.
Returns a filename describing the origin. This will return null if the origin was not a file.
- Returns:
filename of the origin or null
Returns a line number where the value or exception originated. This will return -1 if there's no meaningful line number.
Returns a line number where the value or exception originated. This will return -1 if there's no meaningful line number.
- Returns:
line number or -1 if none is available
Returns a classpath resource name describing the origin. This will return null if the origin was not a classpath resource.
Returns a classpath resource name describing the origin. This will return null if the origin was not a classpath resource.
- Returns:
resource name of the origin or null
Returns a URL describing the origin. This will return null if the origin has no meaningful URL.
Returns a URL describing the origin. This will return null if the origin has no meaningful URL.
- Returns:
url of the origin or null
Returns a ConfigOrigin
based on this one, but with the given
comments. Does not modify this instance or any ConfigValue
s 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 ConfigValue
s 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
- Returns:
the ConfigOrigin with the given comments
- Since:
1.3.0
Returns a ConfigOrigin
based on this one, but with the given line
number. This origin must be a FILE, URL or RESOURCE. Does not modify this
instance or any ConfigValue
s with this origin (since they are
immutable). To set the returned origin to a ConfigValue
, use
ConfigValue#withOrigin.

Note that when the given lineNumber are equal to the lineNumber on this
object, a new instance may not be created and this
is returned
directly.
- Value parameters:
- lineNumber
the new line number
- Returns:
the created ConfigOrigin
