Create a Document Using a Document Object in Java OJAI

You can create a new JSON document in your Java OJAI client by first calling the Connection.newDocument() method to create a Document object, and then calling methods on the object to specify document fields and values.

The following shows the detailed sequence of steps:

  1. Create a new JSON document by calling the newDocument() method in the Connection class.
  2. Specify the ID of the document with the setId() method.
  3. Specify field names and their values with the set() or setArray() method.
  4. Return the results in a Document object.

For example, suppose you want to create the following JSON document: 

{
    "_id" : "movie0000001",
    "title" : "OJAI -- The Documentary",
    "studio" : "MapR Technologies, Inc.",
    "release_date" : "2015-09-29",
    "trailers" : {
        "teaser" : "https://10.10.21.90/trailers/teaser",
        "theatrical" : "https://10.10.21.90/trailers/theatrical"
    },
    "characters" : [
        "Heroic Developer", 
        "Evil Release Manager", 
        "Mad Development Manager"
    ],
    "box_office_gross" : 1000000000L
}

The following method creates the document:

public Document buildDocument() {
    return connection.newDocument()
        .setId("movie0000001")
        .set("title", "OJAI -- The Documentary")
        .set("studio", "MapR Technologies, Inc.")
        .set("release_date", Values.parseDate("2015-09-29"))
        .set("trailers.teaser", "https://10.10.21.90/trailers/teaser")
        .set("trailers.theatrical", "https://10.10.21.90/trailers/theatrical")
        .setArray("characters", 
            ImmutableList.of(
                "Heroic Developer", "Evil Release Manager", "Mad Development Manager"))
        .set("box_office_gross", 1000000000L);
}
