In Groovy, you can bound the arguments of a method call to a list.
For example, in the below snippet, I defined a function 'sum' that takes two integers and return the sum of two integers. While calling I used the Spread Operator to bound the list to the method arguments.
int sum(int a, int b){
return a + b
}
def args1 = [2, 3]
int result1 = sum(*args1)
Find the below working application.
HelloWorld.groovy
int sum(int a, int b){
println "a : ${a}, b : ${b}"
return a + b
}
int sum(int a, int b, int c){
println "a : ${a}, b : ${b}, c : ${c}"
return a + b + c
}
def args1 = [2, 3]
def args2 = [2, 3, 5]
int result1 = sum(*args1)
int result2 = sum(*args2)
println "result1 : ${result1}"
println "result2 : ${result2}"
Output
a : 2, b : 3
a : 2, b : 3, c : 5
result1 : 5
result2 : 10
