    Property [ <default> private $string ]
    Property [ <default> protected $code ]
    Property [ <default> protected $file ]
    Property [ <default> protected $line ]
    Property [ <default> private $trace ]
    Property [ <default> private $previous ]
  }

  - Methods [10] {
    Method [ <internal:Core> final private method __clone ] {
    }

    Method [ <internal:Core, ctor> public method __construct ] {

      - Parameters [3] {
        Parameter #0 [ <optional> $message ]
        Parameter #1 [ <optional> $code ]
        Parameter #2 [ <optional> $previous ]
      }
    }

    Method [ <internal:Core> final public method getMessage ] {
    }

    Method [ <internal:Core> final public method getCode ] {
    }

    Method [ <internal:Core> final public method getFile ] {
    }

    Method [ <internal:Core> final public method getLine ] {
    }

    Method [ <internal:Core> final public method getTrace ] {
    }

    Method [ <internal:Core> final public method getPrevious ] {
    }
