Argumentos con Valores por Defecto

Groovy supports also the usage of methods with default values for parameters.

Ejemplo:

          def foo(x=1, y=2) { x+y }
          assert foo() == 3
          assert foo(2) == 4
          assert foo(5,10) == 15

Any parameter T t can have a default value using T t=x,

where x is the value. In fact this is a short form to declare an overloaded method.

                  def foo(p1, p2, ..., pn, T t=x, q1, q2, ..., qm)

becomes a method

                  def foo(p1, p2, ..., pn, T t, q1, q2, ..., qm)

where t has no default value and a method

                  def foo(p1, p2, ..., pn, q1, q2, ..., qm)

with this implementation:

  def foo(p1, p2, ..., pn, q1, q2, ..., qm) {
    foo(p1, p2, ..., pn, x, q1, q2, ..., qm)
  }
