@@ -85,19 +74,8 @@ Name  | Purpose
 `$file` | `string`; the name of the script where the exception was generated
 `$line` | `int`; the source line number in the script where the exception was generated
 `$message`  | `string`; the exception message (as provided by the constructor)
-`$previous` | The previous exception in the chain, if this is a nested exception; otherwise, `NULL`
-`$string` | Work area for `__toString`
-`$trace`  | Work area for function-call tracing
 `__construct` | Takes three (optional) arguments – `string`: the exception message (defaults to ""), `int`: the exception code (defaults to 0), and `Exception`: the previous exception in the chain (defaults to `NULL`)
 `__clone` | Present to inhibit the cloning of exception objects
-`__toString`  | `string`; retrieves a string representation of the exception in some unspecified format
-`getCode` | `mixed`; retrieves the exception code (as set by the constructor). For an exception of type Exception, the returned value has type int; for subclasses of `Exception`, it may have some other type.
-`getFile` | `string`; retrieves the name of the script where the exception was generated
-`getLine` | `int`; retrieves the source line number in the script where the exception was generated
-`getMessage`  | `string`; retrieves the exception message
-`getPrevious` | `Exception`; retrieves the previous exception (as set by the constructor), if one exists; otherwise, `NULL`
-`getTrace`  | `array`; retrieves the function [stack trace information](#tracing-exceptions) as an array
-`getTraceAsString`  | `string`; retrieves the function stack trace information formatted as a single string in some unspecified format
