我正在研究 Cloudsim。我想为自己的工作更改 PowerVmAllocationPolicyAbstract 类的 findHostForVm() 方法。我将 findHostForVm() 更改为抽象方法,如下所示
public abstract class PowerVmAllocationPolicyAbstract extends VmAllocationPolicy {
public PowerVmAllocationPolicyAbstract(List<? extends Host> list) {
super(list);
}
public abstract PowerHost findHostForVm(Vm vm) ;
.
.
}
在我自己的课程中,我写了 findHostForVm(Vm vm) 。当我从 powerDatacenter 创建实例时,一个参数需要参考 PowerVmAllocationPolicyAbstract 。我在下面写了
public class D{
public PowerHost findHostForVm(List<Vm> vmlist) {
.
.
}
powerDatacenter = new PowerDatacenter(
name,
characteristics,
new D(),
new LinkedList<Storage>(),
5.0);
}
但它有错误。这个错误是:
constructor PowerDatacenter in class org.cloudbus.cloudsim.power.PowerDatacenter cannot be applied to given types;
required: java.lang.String,org.cloudbus.cloudsim.DatacenterCharacteristics,org.cloudbus.cloudsim.VmAl locationPolicy,java.util.List<org.cloudbus.cloudsim.Storage>,double
found: java.lang.String,org.cloudbus.cloudsim.DatacenterCharacteristics,cs.umu.se.vmp.alg. D,java.util.LinkedList<org.cloudbus.cloudsim.Storage>,double
reason: actual argument cs.umu.se.vmp.alg. D cannot be converted to org.cloudbus.cloudsim.VmAllocationPolicy by method invocation conversion
请帮帮我我该怎么办?多谢
