Calling the toSource
method of an Error
instance (including NativeErrors) will return a string containing the source code of the error. This string can be evaluated to create an (approximately) equal object. Naturally, the string containing the source follows the structure of the Error
constructor. For example:
(newname(message ,fileName,lineNumber))
where these attributes correspond to the respective properties of the error instance.
Note: Be aware that the properties used by the toSource
method in the creation of this string are mutable and may not accurately reflect the function used to create an error instance or the filename or line number where the actual error occurred.
