jsonRead

public <T> T jsonRead(Class<T> clazz,
 InputStream is)

Description copied from interface: JsonService

**Reads JSON from an InputStream**

Reads a JSON-formatted input stream and deserializes it into a Java object of the specified type.

Specified by:

jsonRead in interface JsonService

Parameters:

clazz - the Class object of the desired type

is - the input stream containing the JSON data

Returns:

the deserialized object

jsonWrite

public void jsonWrite(Object bean,
 OutputStream os)

Description copied from interface: JsonService

**Writes a Java Object as JSON to an OutputStream**

Serializes a Java object into JSON format and writes the resulting JSON to the specified output stream.

Specified by:

jsonWrite in interface JsonService

Parameters:

bean - the Java object to be serialized

os - the output stream to write the JSON data to

jsonWriteStream

public <T> void jsonWriteStream(Iterator<T> iterator,
 OutputStream os)

Description copied from interface: JsonService

Serializes a stream of Java objects into a JSON-Stream format, using the x-json-stream media type. Each object in the stream is serialized as a separate JSON object, and the objects are separated by newlines.

Specified by:

jsonWriteStream in interface JsonService

Parameters:

iterator - the stream of objects to be serialized

os - the output stream to write the JSON-Stream data to
