groovy Spread Operator Accessing a property
Example
class Vector {
double x
double y
}
def points = [
new Vector(x: 10, y: -5),
new Vector(x: -17.5, y: 3),
new Vector(x: -3.3, y: -1)
]
assert points*.x == [10, -17.5, -3.3]
Note: The * is optional. We could also write the above statement as in the below line and Groovy compiler would still be happy about it.
assert points.x == [10, -17.5, -3.3]
