Examples with JsonGenerator jakarta.json.stream.JsonGenerator used on opensource projects

Example 1 with JsonGenerator

use of jakarta.json.stream.JsonGenerator in project opensearch-java by opensearch-project.

the class JsonDataImpl method getParser.

private JsonParser getParser(JsonpMapper mapper) {
    // FIXME: inefficient roundtrip through a string. Should be replaced by an Event buffer structure.
    StringWriter sw = new StringWriter();
    JsonGenerator generator = mapper.jsonProvider().createGenerator(sw);
    if (value instanceof JsonValue) {
        generator.write((JsonValue) value);
    } else {
        mapper.serialize(value, generator);
    }
    generator.close();
    return mapper.jsonProvider().createParser(new StringReader(sw.toString()));
}

Example 2 with JsonGenerator

use of jakarta.json.stream.JsonGenerator in project opensearch-java by opensearch-project.

the class JsonpMapperTest method testSerialize.

private void testSerialize(JsonpMapper mapper, String expected) {
    SomeClass something = new SomeClass();
    something.setIntValue(1);
    something.setDoubleValue(2.1);
    something.setStringValue("foo");
    SomeClass other = new SomeClass();
    other.setIntValue(2);
    other.setDoubleValue(3.2);
    something.setChildren(Collections.singletonList(other));
    StringWriter strw = new StringWriter();
    JsonGenerator generator = mapper.jsonProvider().createGenerator(strw);
    mapper.serialize(something, generator);
    generator.close();
    assertEquals(expected, strw.getBuffer().toString());
}
