Can a method be passed a long list of parameters?
Instead of a long list of parameters, a method can use the data of its own object. If the current object doesn’t contain all necessary data, another object (which will get the necessary data) can be passed as a method parameter. Check what values are passed to parameters.
When to replace a parameter with a method call?
If some of the arguments are just results of method calls of another object, use Replace Parameter with Method Call. This object can be placed in the field of its own class or passed as a method parameter.
When to use another object as a parameter?
If the current object doesn’t contain all necessary data, another object (which will get the necessary data) can be passed as a method parameter. Check what values are passed to parameters. If some of the arguments are just results of method calls of another object, use Replace Parameter with Method Call.
