Convert JSONSteam to JSON String

To convert a JSONStream to a JSON string, you can use one of the following options depending on the specific InterSystems capabilities:

1. If the JSONStream holds JSON data and you need to convert it to a JSON string, you can use the %ToJSON() method available for dynamic entities:

   set jsonString = jsonStream.%ToJSON()
   

   This will return the JSON as a string. If the output needs to be written to another stream, you can pass an output stream as a parameter to %ToJSON() 12.

2. If the JSON data is contained within a character stream and you’d like to convert it into a string to process further, you can read the stream to aggregate its content:

   set jsonString = ""
   while 'jsonStream.AtEnd {
      set jsonString = jsonString _ jsonStream.Read()
   }
   

   This approach aggregates each chunk read from the stream into one complete JSON string 1.

These processes ensure the JSONStream data is correctly formatted and available as a JSON string, facilitating its use in subsequent operations.
