ConfigOrigin

```
public interface 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.

```
java.lang.String description()
```
    Returns a string describing the origin of a value or exception. This will never return null.
    
    Returns:
    
    string describing the origin
  - filename
```
java.lang.String filename()
```
    Returns a filename describing the origin. This will return null if the origin was not a file.
    
    Returns:
    
    filename of the origin or null
  - url
```
java.net.URL 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
  - resource
```
java.lang.String 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
  - lineNumber
```
int lineNumber()
```
    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
  - comments
```
java.util.List<java.lang.String> comments()
```
    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
  - withComments
```
withComments(java.util.List<java.lang.String> comments)
```
    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(com.typesafe.config.ConfigOrigin).
    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.
    
    Parameters:
    
    comments - the comments used on the returned origin
    
    Returns:
    
    the ConfigOrigin with the given comments
    
    Since:
    
    1.3.0
  - withLineNumber
```
withLineNumber(int lineNumber)
```
    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 ConfigValues with this origin (since they are immutable). To set the returned origin to a ConfigValue, use ConfigValue.withOrigin(com.typesafe.config.ConfigOrigin).
    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.
    
    Parameters:
    
    lineNumber - the new line number
    
    Returns:
    
    the created ConfigOrigin
    
    Since:
    
    1.3.0
