22. def withCloseable[T <: AnyRef { def close(): Unit }, R](closeable: T)(code: (T) ⇒ R): R

    Used with any object that contains a close() method that returns nothing, withCloseable() executes a block of code with the closeable object, ensuring that the object is closed no matter what.

    Used with any object that contains a close() method that returns nothing, withCloseable() executes a block of code with the closeable object, ensuring that the object is closed no matter what. It allows you to replace code like this:

    val closeableObject = ...
    try {
      doSomethingWith(closeableObject)
    }
    finally {
      closeableObject.close
    }
    

    with:

    withCloseable(closeableObject) { closeable =>
      doSomethingWith(closeable)
    }
    

    code

    the block of code, which will take the closeable object and return some arbitrary type R.

    returns

    whatever the code block returns,if anything.
