Class JsonEncoder

java.lang.Object
  org.addsimplicity.anicetus.io.JsonEncoder

All Implemented Interfaces:

TelemetryEncoder

public class JsonEncoder
extends java.lang.Object
implements TelemetryEncoder

The encoder translates telemetry into a JSON string. The object graph is fully exported. In addition to serializing telemetry artifacts, the application can also set classes that are to be treated like beans when serializing. If an object is not a telemetry object and is not a bean, then its toString method is used to generate the value.

Method Detail

addDefaultBeanType

public static void addDefaultBeanType(java.lang.Class<? extends java.lang.Object> beanType)

Add a default bean type. This type will be global and apply to all encoders.

Parameters:

beanType - The class of the bean type to add.

addBeanType

public void addBeanType(java.lang.Class<? extends java.lang.Object> bean)

Add a class to be treated as a bean during encoding.

Parameters:

bean - The class of the bean object.

encode

public char[] encode(GlobalInfo session)

Encode the telemetry graph as JSON.

Specified by:

encode in interface TelemetryEncoder

Parameters:

session - The telemetry graph to encode.

Returns:

the JSON string as a character array.

getBeanTypes

public java.util.Set<java.lang.Class<? extends java.lang.Object>> getBeanTypes()

Return the current list of bean types in use by the encoder.

Returns:

the set of bean types.

getExceptionHandler

public ExceptionHandler getExceptionHandler()

Return the exception handler currently in effect.

Returns:

the exception handler.

setBeanTypes

public void setBeanTypes(java.util.Set<java.lang.Class<? extends java.lang.Object>> beanTypes)

Set the bean types that will be used during JSON encoding. This set is added to the current set.

Parameters:

beanTypes - The set of bean types to be added to the list.

setExceptionHandler

public void setExceptionHandler(ExceptionHandler exceptionHandler)

Set the exception handler that will receive exceptions encountered during encoding.

Parameters:

exceptionHandler - The exception handler.
