如何在OpenMDAO 1.x.x中对参数和未知数使用严格的数据类型？

from openmdao.api import Float

class MyComponent(Component):
    x = Float(0.0, iotype='in', desc='Input parameter')

    def execute(self):
        # 使用参数x进行计算
        pass

from openmdao.api import Int

class MyComponent(Component):
    n = Int(0, iotype='in', desc='Number of iterations')

    def execute(self):
        # 使用参数n进行循环迭代
        pass

from openmdao.api import Array

class MyComponent(Component):
    vec = Array(np.zeros((3,)), iotype='in', desc='Input vector')

    def execute(self):
        # 使用参数vec进行向量运算
        pass
