1. For today's quest, you will be looking at a contract and a script. You will be looking at 4 variables (a, b, c, d) and 3 functions (publicFunc, contractFunc, privateFunc) defined in SomeContract. In each AREA (1, 2, 3, and 4), I want you to do the following: for each variable (a, b, c, and d), tell me in which areas they can be read (read scope) and which areas they can be modified (write scope). For each function (publicFunc, contractFunc, and privateFunc), simply tell me where they can be called.
access(all) contract SomeContract {
pub var testStruct: SomeStruct
pub struct SomeStruct {
//
// 4 Variables
//
pub(set) var a: String
pub var b: String
access(contract) var c: String
access(self) var d: String
//
// 3 Functions
//
pub fun publicFunc() {}
access(contract) fun contractFunc() {}
access(self) fun privateFunc() {}
pub fun structFunc() {
/**************/
/*** AREA 1 ***/
/**************/
}
init() {
self.a = "a"
self.b = "b"
self.c = "c"
self.d = "d"
}
}
pub resource SomeResource {
pub var e: Int
pub fun resourceFunc() {
/**************/
/*** AREA 2 ***/
/**************/
}
init() {
self.e = 17
}
}
pub fun createSomeResource(): @SomeResource {
return <- create SomeResource()
}
pub fun questsAreFun() {
/**************/
/*** AREA 3 ****/
/**************/
}
init() {
self.testStruct = SomeStruct()
}
}This is a script that imports the contract above:
import SomeContract from 0x01
pub fun main() {
/**************/
/*** AREA 4 ***/
/**************/
}THE NEW ANSWER:
AREA 1
Read Scope: a, b, c, d
Write Scope: a, b, c, d
publicFunc, contractFunc, privateFunc can be called here
AREA 2:
Read Scope: a, b, c
Write Scope: a
publicFunc, contractFunc can be called here
AREA 3:
Read Scope: a, b, c
Write Scope: a
publicFunc, contractFunc can be called here
AREA 4:
Read Scope: a, b
Write Scope: None of the variables are in the write scope of Area 4 because no data that's already on the blockchain can be changed inside a script.
publicFunc can be called here
THE OLD ANSWER:
AREA 1
Read Scope: a, b, c, d
Write Scope: a, b, c, d
publicFunc, contractFunc, privateFunc can be called here
AREA 2:
Read Scope: a, b, c
Write Scope: a, b, c
publicFunc, contractFunc can be called here
AREA 3:
Read Scope: a, b, c
Write Scope: a, b, c
publicFunc, contractFunc can be called here
AREA 4:
Read Scope: a, b
Write Scope: a
publicFunc can be called here
