Hi
Have one doubt
I try to re assign some different value (which is below range of 5) in student's firstName and lastName but it cannot assign again
In output, it shows old value

[@bharath7730]

is NameDelegate object created for each property or there is only one object for every property. Because if it create objects for each property then it may be inefficient.

[@jasdevsingh6795]

Can't we achieve the same with extension functions ?

[@namrathabharadwaj8945]

Hey Belal. How is this delegation any different than creating a common private method to avoid redundant code? I mean what is the significance of delegation over creating a common method in this case?

[@SimplifiedCoding]

Can you submit your version of the code?

[@junigates]

confusing with operator fun , by the way great info

[@vidyesh]

Custom implementation of the 'setValue' operator using operator overloading.

[@arjundixit5913]

Okay I understand delegation, but what would be called as delegate in the above example?

[@deepakbisht4957]

It is delegation in the sense that you are sending validation responsibility to another class that actually validating the first and last name.

[@shashankrana977]

Viradar you threw Kproperty and operator keyword without explaining, I finding it difficult to follow this way

[@shreyashchoudhary7413]

Loved it!

[@ravipratapsingh3428]

How I want check varriavble value is even only using a single variable not a class

[@amitrajj]

This can be done easily by using Extension functions.

[@Saranshhanda]

thanks man!

[@master8994]

I didn't understand the property thing please someone explain

[@avishekthapa6655]

cant we just create a function that does the validation and used that validation in setter and getter like this
class Student {
var firstName: String? = null
set(value) {
if (isValid(value))
field = value?.trim()?.toUpperCase()
}
var secondName: String? = null
set(value) {
if (isValid(value))
field = value?.trim()?.toUpperCase()
}
private fun isValid(data: String?) = data != null && data.length > 5
}

[@SimplifiedCoding]

Still the delegation is more concise as you can clearly see.
