Groovy Goodness: Represent Map As String
Groovy adds to Map objects the toMapString method.
With this method we can have a String representation of our Map.
We can specify an argument for the maximum width of the generated String.
Groovy will make sure at least the key/value pairs are added as a pair, before adding three dots (...) if the maximum size is exceeded.
def course = [
name: 'Groovy 101',
teacher: 'mrhaki',
location: 'The Netherlands']
assert course.toMapString(15) == '[name:Groovy 101, ...]'
assert course.toMapString(25) == '[name:Groovy 101, teacher:mrhaki, ...]'
As mentioned in a previous post we can use the toListString method to represent a List as a String:
def names = ['mrhaki', 'hubert']
assert names.toListString(5) == '[mrhaki, ...]'
