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.

  private byte[] getStorageJSON() {
    // 256 bytes is a good starting value, assumes default info
    final ByteArrayOutputStream output = new ByteArrayOutputStream(256);
    try {
      final JsonGenerator json = JSON.getFactory().createGenerator(output); 
      json.writeStartObject();
      json.writeStringField("uid", uid);
      json.writeStringField("type", type.toString());
      json.writeStringField("name", name);
      json.writeStringField("displayName", display_name);
      json.writeStringField("description", description);
