Examples of org.jets3t.service.model.S3Object.addMetadata()

org.jets3t.service.model.S3Object.addMetadata()
Add metadata information to the object. If date metadata items (as recognized by name) are added and the value is not a date, the value is parsed as an ISO 8601 string.


        // You can also copy an object and update its metadata at the same time. Perform a 
        // copy-in-place  (with the same bucket and object names for source and destination) 
        // to update an object's metadata while leaving the object's data unchanged.
        targetObject = new S3Object("HelloWorld.txt");
        targetObject.addMetadata(S3Object.METADATA_HEADER_CONTENT_TYPE, "text/html");        
        replaceMetadata = true;
        s3Service.copyObject("test-bucket", "HelloWorld.txt", "test-bucket", targetObject, replaceMetadata);
