For faster and efficient checking of the types of values, SRON provides 7 functions

• isVoid()

1. isVoid():

This function returns true if the passed value is Void otherwise false.

{
    name : Main
    Any val = Void

    if : {
        condition : isVoid(val)
        println("Value is Void")
    }
    else : { 
        println("Value is not Void")
    }
}

OUTPUT:

Value is Void

---

2. isInt():

This function returns true if the passed value is of type 'Int' otherwise false.

{
    name : Main
    Any val = 27062003

    if : {
        condition : isInt(val)
        println("Value is an Integer")
    }
    else : { 
        println("Value is not an Integer")
    }
}

OUTPUT:

Value is an integer

---

3. isDouble():

This function returns true if the passed value is of type 'Double' otherwise false.

{
    name : Main
    Any val = 2706.2003

    if : {
        condition : isDouble(val)
        println("Value is a decimal number")
    }
    else : { 
        println("Value is not a decimal number")
    }
}

OUTPUT:

Value is a decimal number

---

4. isChar():

This function returns true if the passed value is of type 'Char' otherwise false.

{
    name : Main
    Any val = 'S'

    if : {
        condition : isChar(val)
        println("Value is a character")
    }
    else : { 
        println("Value is not a character")
    }
}

OUTPUT:

Value is a character

---

5. isBool():

This function returns true if the passed value is of type 'Bool' Void otherwise false.

{
    name : Main
    Any val = false

    if : {
        condition : isBool(val)
        println("Value is a boolean")
    }
    else : { 
        println("Value is not a boolean")
    }
}

OUTPUT:

Value is a boolean

---

6. isCollective():

This function returns true if the passed value is of type 'List' or 'String' otherwise false.

{
    name : Main
    Any val = [1, 2, true, [91, 92]]

    if : {
        condition : isCollective(val)
        println("Value is of collective type")
    }
    else : { 
        println("Value is not of collective type")
    }
}

OUTPUT:

Value is of collective type

---

7. isString():

This function returns true if the passed value is of type 'String' otherwise false.

{
    name : Main
    String val = "SRON"

    if : {
        condition : isString(val)
        println("Value is a string")
    }
    else : { 
        println("Value is not a string")
    }
}

OUTPUT:

Value is a string

---

8. isList():

This function returns true if the passed value is of type 'List' otherwise false.

{
    name : Main
    Any val = [1,2,3,4.177]

    if : {
        condition : isList(val)
        println("Value is a list")
    }
    else : { 
        println("Value is not a list")
    }
}

OUTPUT:

Value is a list

---

9. isFileReader():

This function returns true if the passed value is of type 'FileReader' otherwise false.

{
    name : Main
    Any val = freader("file.txt")

    if : {
        condition : isFileReader(val)
        println("Value is a file reader")
    }
    else : { 
        println("Value is not a file reader")
    }
}

OUTPUT:

Value is a file reader

---

10. isFileWriter():

This function returns true if the passed value is of type 'FileWriter' otherwise false.

{
    name : Main
    Any val = fwriter("file.txt", true)

    if : {
        condition : isFileWriter(val)
        println("Value is a file writer")
    }
    else : { 
        println("Value is not a file writer")
    }
}

OUTPUT:

Value is a file writer

---

11. isLiteralString():

This function returns true if the passed value is of type 'LiteralString' otherwise false.

{
    name : Main
    Any val = "Hi! SRON"

    if : {
        condition : isLiteralString(val)
        println("Value is a LiteralString")
    }
    else : { 
        println("Value is not a LiteralString")
    }
}

OUTPUT:

Value is a LiteralString
