java：如何为变量自动生成自定义方法

Question

I've a situation where i want to define variety of behaviour for my fields.

class SomePage {
    //...

    @FindBy(id = "selectEthinicity")
    private WebElement ethinicitySelect;

    @FindBy(id = "someId")
    private WebElement usernameInputField;

     @FindBy(id = "buttonSubmit")
    private WebElement submitButton;


    public void selectEthnicity(String param) throws Exception {
        new Select(ethnicitySelect).selectByVisibleText(param);
    }

    public void selectEthnicityByIndex(String param) throws Exception {
        new Select(ethnicitySelect).selectByIndex(Integer.parseInt(param));
    }

    public int getSelectEthinicityNumberOfOptions() {
        new Select(ethnicitySelect).getOptions().size();    
    }

    public void waitForOptionOfSelectEthnicityToLoad() {
       //logic to wait for an options of Ethinicity to load
    }

    public void selectEthnicity_Wait(String param) throws Exception {
        //wait 
        //select Ethinicity
    }

    public void selectEthnicityByIndex_Wait(String param) throws Exception {
       //wait and 
       //Select Ethnicity by einde
    }


    //custom method for input Field
    public String getUsernameInputFieldValue() {
        usernameInputField.getAttribute("value");
    }

    public void enterUsernameInputField(String param) {
        usernameInputField.sendKeys(param);
    }


    //custom method for button
    public void clickSubmitButton() throws PageValidationException {
        submitButton.click();
    }

    //...
}

Here I have a class SomePage which is a Page Object (Using Page Factory Pattern) which consist of fields ( WebElement ).

Based on the suffix of field names I need to create number of method. If suffix is *Select the field will have number of methods which can be Similar for all select field . If suffix is *Button it will have a method's that are needed for button field .

Can I generate the Custom Method based upon the suffix of field names .

NOTE: IntelliJ Supports the modification of custom Getters and Setters but it doesn't allow multiple methods per field. It restricts to 1 Getter and 1 Setter per field. Which is not always the case as per example. I my have multiple setter ( kind of setter) or getter for a field.

Answer 1

Generating Getters and Setters in IntelliJ IDEA :

1. On the main menu, choose Code. Alternatively, right-click the editor and choose Generate on the context menu, or use Alt+Insert keyboard shortcut.
2. In the pop-up list that is displayed in the editor, select one of the following options: Getter Accessor method for getting the current value of the selected fields. Setter Mutator method for setting specified values to the selected fields. Getter and Setter Both methods for the selected fields.
3. In the Choose Fields to Generate Getters and Setters dialog box, select the desired fields. You can add a custom setter or getter by clicking browseButton and accessing Getter/Setter Templates dialog. If getters and setters for a field already exist, this field is not included in the list.
4. Click OK.

It is possible to generate custom classes, but dynamic class generation is a fairly advanced feature, and from the sounds of your problem it's unnecessarily complex.

I think you should create a new class for these objects with the same functionality. You should read about Object-Oriented Programming because this is a fairly simple concept. Maybe your example is poor, but why are you redefining String functions for each button? Here's an example of a different design:

public class Button {
    private String text;

    public Button(String text) {
        this.text = text;
    }

    public void setText(String text) {
        this.text = text;
    }

    public String getText() {
        return text;
    }
}

Then just declare a bunch of your new class.

class Temp {
    Button abcButton = new Button("abc");
    Button cdeButton = new Button("cde");

        // Instead of setAbcButtonToLower()
        abcButton.setText(abcButton.getText().toLowerCase());
        // Instead of getAbcButtonIndexOfChar()
        abcButton.getText().indexOf(c);
        // Instead of getAbcButtonSize()
        abcButton.getText().length();
}

You cant generate custom methods automatically . For custom methods you have to define them that's why it is called custom . best you can get are only basic getter and setter methods, I think you already got those
or you can do it like this class Button{ string button }

class buttonProperties{

int buttonLength; int buttonSize;

public int getbuttonSize(){

return buttonSize;

} . . .

}
