java - 将文本转义为 JavaFX 代码

Question

I'm making a Java program that takes some text as input,
and has to produce the equivalent JavaFX code (a String literal). For instance:

The input is the following text:

 Hello World: This. \ is a backslash: And this.  {} are brackets. 

And the resulting JavaFX code is:

 "Hello World: This. \\ is a backslash:\nAnd this. \{\} are brackets."

Is there any native way (for example, using JavaFX SDKs) to achieve this?
If not, can someone give me the complete escaped sequences list in JavaFX?

Answer 1

According to the JavaFX specification , the only characters that you have to escape with a backslash when using double quotation marks are:

• "
• {
• }
• \

Here's a Java method that should do what you're looking for:

public String escapeInput(String[] input) {
    String[] characters = {"\"", "\\", "{", "}"};
    StringBuilder sb = new StringBuilder();
    sb.append("\"");
    for (String line : input) {
        for (String test : characters) {
            line = line.replace(test, "\\" + test);
        }
        sb.append(line);
        sb.append("\n");
    }
    sb.append("\"");
    return sb.toString();
}
