Operators

The Elvis Operator

A more concise ternary operator: ?:

def sampleText
 
// Normal ternary operator.
def ternaryOutput = (sampleText != null) ? sampleText : 'Hello Groovy!'
 
// The Elvis operator in action. We must read: 'If sampleText is not null assign
// sampleText to elvisOuput, otherwise assign 'Viva Las Vegas!' to elvisOutput.
def elvisOutput = sampleText ?: 'Viva Las Vegas!'
