如何使用開關將Javascript匿名函數轉換為Java？
[英]How to convert Javascript Anonymous Function to Java maybe with switch?
問題描述
這是下面的javascript代碼，鏈接了一些匿名內部函數，似乎每個開關都有2個數組索引，它們似乎也返回了一些值，但是我不知道它們在哪里返回memoryReadJumpCompile()函數或這兩個數組指數的。
它們很可能會恢復到實際的數組索引，並且通過函數名Compile似乎每次您調用這些數組索引中的任何一個時，它們都會重新評估鏈接到它們的函數並產生一些新結果，但仍然不知道結果在哪里如果存儲了實際索引的hold函數，則我最好的猜測是實際數組索引就像函數名一樣，它們由另一段代碼返回，而無論其他何處索引都在代碼中的某個地方被調用，但可以說前兩個示例數組索引。
this.memoryHighReader[0] = this.memoryReader[0xFF00]
所以他們都變成了同一件事，我發現它像這樣在指令執行器中得到處理
case 242:
a.registerA = a.memoryHighReader[a.registerC](a, a.registerC);
break;
GameBoyCore.prototype.memoryReadJumpCompile = function () {
//...
else if (index >= 0xFF00) {
switch (index) {
case 0xFF00:
//JOYPAD:
this.memoryHighReader[0] = this.memoryReader[0xFF00] = function (parentObj, address) {
return 0xC0 | parentObj.memory[0xFF00]; //Top nibble returns as set.
}
break;
case 0xFF01:
//SB
this.memoryHighReader[0x01] = this.memoryReader[0xFF01] = function (parentObj, address) {
return (parentObj.memory[0xFF02] < 0x80) ? parentObj.memory[0xFF01] : 0xFF;
}
break;
case 0xFF02:
//SC
if (this.cGBC) {
this.memoryHighReader[0x02] = this.memoryReader[0xFF02] = function (parentObj, address) {
return ((parentObj.serialTimer <= 0) ? 0x7C : 0xFC) | parentObj.memory[0xFF02];
}
}
else {
this.memoryHighReader[0x02] = this.memoryReader[0xFF02] = function (parentObj, address) {
return ((parentObj.serialTimer <= 0) ? 0x7E : 0xFE) | parentObj.memory[0xFF02];
}
}
break;
}
}
以上的JavaScript幾乎像Java，但我不明白如何將轉換function(parentObj, address) {...}在memoryReadJumpCompile什么最簡單的方法將其轉換為Java，而無需使用任何接口。 我想使用一個switch()
這是我到目前為止在Java中擁有的內容（它不使用十六進制字母，因為在開始轉換時使用的是Minified JavaScript版本）

我開始分裂memoryReadJumpCompile放進去組合成memoryHighRead和存儲器讀功能。 每個功能大約需要1個小時。
下面是一個例子memoryReader ，我完成了他們所有的人都4（存儲器讀/ memoryReadHigh / memoryWrite / memoryWriteHigh），不知道是否可行，仍有超過100個錯誤！ 哈哈，任重而道遠。
