Infix functions in Kotlin are a special type of extension functions or member functions that allow you to call them using infix notation, without using the traditional dot and parentheses syntax. This enables you to write more readable and expressive code, especially for certain types of operations or DSLs (Domain-Specific Languages).
Infix functions are defined using the infix keyword. They must have exactly one parameter and are typically associated with binary operations. Here’s an example of an infix function:
kotlin
infix fun Int.isGreaterThan(other: Int): Boolean {
return this > other
}
With this definition, you can now use the isGreaterThan function as an infix operator between two integers:
kotlin val result = 5 isGreaterThan 3
In this example, isGreaterThan is an infix function that checks whether the left-hand side (this) is greater than the right-hand side (other).
