Examples of JsonEncoder

com.jaxws.json.codec.encode.JSONEncoder
@author ssaminathan
com.smartgwt.client.util.JSONEncoder
Class for encoding objects as JSON strings.
org.apache.avro.io.JsonEncoder
An {@link Encoder} for Avro's JSON data encoding.
Construct using {@link EncoderFactory}.
JsonEncoder buffers output, and data may not appear on the output until {@link Encoder#flush()} is called.
JsonEncoder is not thread-safe.
org.jboss.errai.bus.server.io.JSONEncoder
Encodes an object into a JSON string
org.jtester.json.encoder.JSONEncoder
json串加码器基类
解码：从json字符串反序列为java对象
加码：将java对象序列化为json字符串
