What are parameter objects?
Parameter objects represent parameters associated with parameterized queries, or the in/out arguments and the return values of stored procedures. Depending on the functionality of the provider, some collections, methods, or properties of a Parameter object may not be available.
How do you give an object a parameter?
To pass an object as an argument we write the object name as the argument while calling the function the same way we do it for other variables. Syntax: function_name(object_name); Example: In this Example there is a class which has an integer variable ‘a’ and a function ‘add’ which takes an object as argument.
What is a Javadoc file?
Javadoc (originally cased JavaDoc) is a documentation generator created by Sun Microsystems for the Java language (now owned by Oracle Corporation) for generating API documentation in HTML format from Java source code. Writing comments and Javadoc is for better understanding the code and thus better maintaining it.
How to add a parameter to a method?
In the method that you want to refactor, use Add Parameter, which is where your parameter object will be passed. In all method calls, pass the object created from old method parameters to this parameter. Now start deleting old parameters from the method one by one, replacing them in the code with fields of the parameter object.
Can a parameter object be used in a class?
A parameter object is not a class built around a single method, it is a data transfer object, which means it does not have methods at all (or at at least only methods for accessing data). But it could be the starting point for a real class with business methods. Whether a parameter object is a good idea in the first place depends on your code.
How to replace a parameter in a program?
In all method calls, pass the object created from old method parameters to this parameter. Now start deleting old parameters from the method one by one, replacing them in the code with fields of the parameter object. Test the program after each parameter replacement.
How to delete old parameters from a method?
In all method calls, pass the object created from old method parameters to this parameter. Now start deleting old parameters from the method one by one, replacing them in the code with fields of the parameter object.
