Method overloading in groovy
- by slojo
I am trying to take advantage of the convenience of groovy's scripting syntax to assign properties, but having trouble with a specific case. I must be missing something simple here. I define class A, B, C as so:
class A {
A() {
println "Constructed class A!"
}
}
class B {
B() {
println "Constructed class B!"
}
}
class C {
private member
C() {
println "Constructed class C!"
}
def setMember(A a) {
println "Called setMember(A)!"
member = a
}
def setMember(B b) {
println "Called setMember(B)!"
member = b
}
}
And then try the following calls in a script:
c = new C()
c.setMember(new A()) // works
c.member = new A() // works
c.setMember(new B()) // works
c.member = new B() // doesn't work!
The last assignment results in an error: 'Cannot cast object of class B to class A". Why doesn't it call the proper setMember method for class B like it does for class A?
