Identifier LiteralsBallerina supports Identifier literals, that means, it is possible to define symbols without restrictions like "no spaces, no special character" etc. in Ballerina. |
|
import ballerina/io;
|
|
function main (string[] args) {
|
|
string ^"first name" = "John";
string ^"last name" = "Gosling";
|
The vertical bar (|) character is used to demarcate the identifier name. This is similar to string literals (using double quote characters to demarcate). |
string name = ^"combine names"(^"first name", ^"last name");
io:println(name);
}
|
Invoking a function with identifier literal as a parameter. |
function ^"combine names" (string ^"first name",
string ^"last name") returns (string) {
return ^"first name" + " " + ^"last name";
}
|
Sample function defined with function name and input parameter using identifier literals. |
type ^"person record" {
string ^"first name";
string ^"last name";
int age;
};
