好吧,我现在可以做到这一点,但我想知道它是否可以作为“自动”属性更加无缝地完成。从静态方法的内部返回类的新实例?
class Test : PPCNode
{
public static PPCNode ParseCode(string code)
{
string[] codeArray = SplitCode(code);
// return instance of the Instruction Node
return new Test(codeArray, 0);
}
}
所以这基本上是每个说的代码。
现在,这段代码发生在很多类中,所以它是一样的,除了实例是它所在的类。
所以这就是我想知道的,是否有可能通过某种汽车的东西,如新的实例。
“return new ThisClass(....)”,如果你明白了我的意思。
谢谢:)
编辑:
好了来这里一些例子,这将是许多代码,但它很容易看穿。
因此,这里有两大类:
internal class AddicDotInstructionNode : PPCNode
{
private readonly string[] parameterArray;
private AddicDotInstructionNode(string[] codeArray)
{
parameterArray = codeArray;
// Throw exception if the number of parameters is invalid to instruction
if (codeArray.Length != 3)
throw new Exception($"\"{GetType().Name}\" instruction is invalid");
}
public static PPCNode ParseCode(string code)
{
// Split the code string into an array so each element is a parameter
string[] codeArray = code.Split(',');
// return instance of the Instruction Node
return new AddicDotInstructionNode(codeArray);
}

public override int Compile()
{
int opcode = 13;
int regD = Utility.PPCUtility.GetParameterDigit(parameterArray[0]);
int regA = Utility.PPCUtility.GetParameterDigit(parameterArray[1]);
int simm = Utility.PPCUtility.Get16bitHexorDecimalAsUint(parameterArray[2]);
// opcode at 0-5 (26-31)
// Register D at 6-10 (21-25)
// Register A at 11-15 (16-20)
// SIMM at 16-31 (0-15)
return opcode << 26 | regD << 21 | regA << 16 | simm;
}
}
内部类AddicInstructionNode:PPCNode { 私人只读字符串[] parameterArray;
private AddicInstructionNode(string[] codeArray)
{
parameterArray = codeArray;
// Throw exception if the number of parameters is invalid to instruction
if (codeArray.Length != 3)
throw new Exception($"\"{GetType().Name}\" instruction is invalid");
}
public static PPCNode ParseCode(string code)
{
// Split the code string into an array so each element is a parameter

return new AddicInstructionNode(codeArray);
}

public override int Compile()
{
int opcode = 12;
int regD = Utility.PPCUtility.GetParameterDigit(parameterArray[0]);
int regA = Utility.PPCUtility.GetParameterDigit(parameterArray[1]);
int simm = Utility.PPCUtility.Get16bitHexorDecimalAsUint(parameterArray[2]);
// opcode at 0-5 (26-31)

return opcode << 26 | regD << 21 | regA << 16 | simm;
}
}

对不起,我吨的代码,但你可以看到它一遍又一遍基本上同样的事情,但每个类都有差异,通常在同一类别中,它们仅相差1或2个常数值。
因此,因为有很多复制粘贴和重复使用几乎相同的类一遍又一遍,我试图找到方法使它更加无缝。 P
有办法移动代码,但我不确定你认为应该如何使它更加无缝。也许你想工作的更完整的例子? – BradleyDotNET
当然会给一个更清晰的图片:) – Zerowalker
你是否要求一些泛型静态方法,提供你想要什么类的实例??? – SSH
