Class Method Details

.open(output) ⇒ Object

With no associated block, Output::open is a synonym for Output::new. If the optional code block is given, it will be passed the new writer as an argument and the Output object will automatically be closed when the block terminates. In this instance, Output::open returns the value of the block.
