Java TaggedOutputStream-class And Method Code Example

Here is an example of how to use the TaggedOutputStream class from the package in Java:

import java.util.HashMap;
import java.util.Map;


public class Example {
    public static void main(String[] args) throws IOException {
        FileOutputStream fileOutputStream = new FileOutputStream("example.txt");
        Map<String, Object> tags = new HashMap<>();
        tags.put("author", "John Smith");
        tags.put("date", "2022-01-01");
        TaggedOutputStream taggedOutputStream = new TaggedOutputStream(fileOutputStream, tags);
        taggedOutputStream.write("Hello, World!".getBytes());

This example creates a FileOutputStream to write to a file named "example.txt", and then wraps it in a TaggedOutputStream. It also creates a map of tags, with keys "author" and "date" and values "John Smith" and "2022-01-01" respectively. The write method is called on the taggedOutputStream object to write the bytes of the string "Hello, World!" to the file. The flush method is called to flush any remaining bytes to the file, and the close method is called to close the stream.

You can use the getTags method to get the tags and setTag method to set the tag on the TaggedOutputStream class.

Note that, the TaggedOutputStream is not intended to be used as a general-purpose class, it is intended to be used only in situations where you need to write a stream to a file and also attach metadata to it.
