Class com.fasterxml.jackson.core.JsonGenerator

Examples of com.fasterxml.jackson.core.JsonGenerator.writeStartObject()

com.fasterxml.jackson.core.JsonGenerator.writeStartObject()
Method for writing starting marker of a JSON Object value (character '{'; plus possible white space decoration if pretty-printing is enabled).
Object values can be written in any context where values are allowed: meaning everywhere except for when a field name is expected.

          json.writeStartObject();
          
          json.writeStringField("metric", dps.metricName());
          
          json.writeFieldName("tags");
          json.writeStartObject();
          if (dps.getTags() != null) {
            for (Map.Entry<String, String> tag : dps.getTags().entrySet()) {
              json.writeStringField(tag.getKey(), tag.getValue());
            }
          }
