Has anyone worked with Amazon Ion? (https://amzn.github.io/ion-docs/guides/cookbook.html)
I have to write a doc with IonWriter
, the problem being that the schema needs something like this:
{
name: "schemaName",
valid: [a, b, c]
}
but I am unable to find a way to write [a,b,c]
without quotes.
Things I have tried:
writeString()
by converting list to stringwriteByte()
that resulted in byte data which is not requiredwriteSymbol()
that resulted in same as string.Is there a way to do this?
It looks like the use case of data type symbol
based on Amazon ION specification https://amzn.github.io/ion-docs/docs/spec.html#symbol, you can try code below.
import com.amazon.ion.IonStruct;
import com.amazon.ion.IonSystem;
import com.amazon.ion.system.IonSystemBuilder;
public class IonSample {
public static void main(String[] args) {
IonSystem ionSystem = IonSystemBuilder.standard().build();
IonStruct ionStruct = ionSystem.newEmptyStruct();
ionStruct.add("name", ionSystem.newString("schemaName"));
ionStruct.add("valid", ionSystem.newList(
ionSystem.newSymbol("a"),
ionSystem.newSymbol("b"),
ionSystem.newSymbol("c")));
System.out.println(ionStruct.toPrettyString());
}
}
Output
{
name:"schemaName",
valid:[
a,
b,
c
]
}
