对函数的调用不对应于任何重载
the call to a function does not correspond to any overload of
我正在开发一个 java 库来管理 Crystal 报告中的不同种类的条形码。 Crystal Report 为 Eclipse 提供了一个 sdk，在一个新项目中有用于开发 ERP 和 CR 之间集成的库。这个库中有一个管理条形码，但它是一个糟糕的库，因为我只能管理一种条形码。我找到了一个实现UFL的文档。该文档提供了一个简单的示例，感谢我写了一些 class 来管理三种条形码，但是有一些 Crystal 带有两个参数的报告函数，并且该示例没有显示如何获取正确的实施。我试图开发新的 classes 来管理那种功能，但我总是收到错误消息："the call to a function does not correspond to any overload of 'name of function'".
对于这个函数，我尝试只传递一个参数，应用程序 运行 很好。我对该方法进行了重载，传递了两个参数，但我总是收到相同的错误消息。
这是我的代码的一部分
public final FormulaValue evaluate(FormulaValueReference[] arguments)
throws FormulaFunctionCallException
{
StringValue dataStringArg = (StringValue)arguments[0].getFormulaValue();
StringValue opzArg =(StringValue)arguments[1].getFormulaValue();
String dataString = dataStringArg.getString();
String opz=opzArg.getString();
String returnVal = doTranslation(dataString,opz);
return StringValue.fromString(returnVal);
}
protected abstract String translate(String inputData,String opz)
throws InvalidBarcodeDataException;
public class CodeEAN13
extends CodeEAN13Base
{
public String getIdentifier()
{
return "barcodeean13";
}
protected String translate(String inputData, String opz) throws InvalidBarcodeDataException {
Integer checkDigitSubtotal;
.....
}
我除了显示带有那种条形码的报告。 CodeEAN13 class 应该 运行 一种计算条形码字体字符串的算法。
这是程序 运行 时库中的代码，并显示在堆栈跟踪中。对于 stracktrace 的每一行，我都放置了相应的代码。

堆栈跟踪告诉您您需要知道的内容，但是我无法提供更具体的信息，因为 Crystal 报告似乎是付费墙并且他们不提供文档（至少是免费的）所以我不能查看jar的来源。
无论如何，这个片段告诉你大部分你需要知道的：

这一行：
com.crystaldecisions.reports.formulas.FormulaException
告诉您抛出的异常来自 Crystal 报告源代码，而不是 Java 特定错误。因此，如果可以，您应该查阅文档（如果您有权访问）或检查源代码以查看导致抛出的条件.如果您不确定如何操作，您可以在问题中添加一些此类信息，我或其他人可以尝试提供帮助。
at com.crystaldecisions.reports.formulas.j.a(SourceFile:3528)
括号中的部分告诉您在哪里查找异常源 SourceFile，可能但不一定在第 3528 行。此行号在实践中可能不同，特别是如果您正在查看的代码是反编译，所以如果事情没有按预期排列，您可能需要四处寻找确切的行。
遗憾的是，如果没有文档或源代码，将很难为您提供进一步的帮助。
问题出在这条语句上：
FormulaFunctionArgumentDefinition[] myArguments = {SimpleFormulaFunctionArgumentDefinition.string };
参数的正确配置是：
FormulaFunctionArgumentDefinition[] myArguments = { SimpleFormulaFunctionArgumentDefinition.string,SimpleFormulaFunctionArgumentDefinition.string };
显然在我的Crystal 报表公式中有两种字符串类型或一种字符串类型，具体取决于公式。

我正在开发一个 java 库来管理 Crystal 报告中的不同种类的条形码。 Crystal Report 为 Eclipse 提供了一个 sdk，在一个新项目中有用于开发 ERP 和 CR 之间集成的库。这个库中有一个管理条形码，但它是一个糟糕的库，因为我只能管理一种条形码。我找到了一个实现UFL的文档。该文档提供了一个简单的示例，感谢我写了一些 class 来管理三种条形码，但是有一些 Crystal 带有两个参数的报告函数，并且该示例没有显示如何获取正确的实施。我试图开发新的 classes 来管理那种功能，但我总是收到错误消息："the call to a function does not correspond to any overload of 'name of function'".
对于这个函数，我尝试只传递一个参数，应用程序 运行 很好。我对该方法进行了重载，传递了两个参数，但我总是收到相同的错误消息。
这是我的代码的一部分
public final FormulaValue evaluate(FormulaValueReference[] arguments)
throws FormulaFunctionCallException
{
StringValue dataStringArg = (StringValue)arguments[0].getFormulaValue();
StringValue opzArg =(StringValue)arguments[1].getFormulaValue();
String dataString = dataStringArg.getString();
String opz=opzArg.getString();
String returnVal = doTranslation(dataString,opz);
return StringValue.fromString(returnVal);
}
protected abstract String translate(String inputData,String opz)
throws InvalidBarcodeDataException;
public class CodeEAN13
extends CodeEAN13Base
{
public String getIdentifier()
{
return "barcodeean13";
}
protected String translate(String inputData, String opz) throws InvalidBarcodeDataException {
Integer checkDigitSubtotal;
.....
}
我除了显示带有那种条形码的报告。 CodeEAN13 class 应该 运行 一种计算条形码字体字符串的算法。
这是程序 运行 时库中的代码，并显示在堆栈跟踪中。对于 stracktrace 的每一行，我都放置了相应的代码。

堆栈跟踪告诉您您需要知道的内容，但是我无法提供更具体的信息，因为 Crystal 报告似乎是付费墙并且他们不提供文档（至少是免费的）所以我不能查看jar的来源。
无论如何，这个片段告诉你大部分你需要知道的：

这一行：
com.crystaldecisions.reports.formulas.FormulaException
告诉您抛出的异常来自 Crystal 报告源代码，而不是 Java 特定错误。因此，如果可以，您应该查阅文档（如果您有权访问）或检查源代码以查看导致抛出的条件.如果您不确定如何操作，您可以在问题中添加一些此类信息，我或其他人可以尝试提供帮助。
at com.crystaldecisions.reports.formulas.j.a(SourceFile:3528)
括号中的部分告诉您在哪里查找异常源 SourceFile，可能但不一定在第 3528 行。此行号在实践中可能不同，特别是如果您正在查看的代码是反编译，所以如果事情没有按预期排列，您可能需要四处寻找确切的行。
遗憾的是，如果没有文档或源代码，将很难为您提供进一步的帮助。
问题出在这条语句上：
FormulaFunctionArgumentDefinition[] myArguments = {SimpleFormulaFunctionArgumentDefinition.string };
参数的正确配置是：
FormulaFunctionArgumentDefinition[] myArguments = { SimpleFormulaFunctionArgumentDefinition.string,SimpleFormulaFunctionArgumentDefinition.string };
显然在我的Crystal 报表公式中有两种字符串类型或一种字符串类型，具体取决于公式。 下面是解决具有两个参数的条形码函数的 UFL 的完整代码。此代码为 Crystal 报告设置 UFL 库。
