                    com.google.gson.JsonIOException,
                    com.google.gson.JsonSyntaxException

Specified by:

read in class com.google.gson.TypeAdapter<Message>

Throws:

java.io.IOException

com.google.gson.JsonIOException

com.google.gson.JsonSyntaxException

parseResult

protected java.lang.Object parseResult(com.google.gson.stream.JsonReader in,
                                       java.lang.String id)
                                throws com.google.gson.JsonIOException,
                                       com.google.gson.JsonSyntaxException

Convert the json input into the result object corresponding to the call made by id. If the id is not known until after parsing, call parseResult(Object, String) on the return value of this call for a second chance conversion.

Parameters:

in - json input to read from

id - id of request message this is in response to

Returns:

correctly typed object if the correct expected type can be determined, or a JsonElement representing the result

Throws:

com.google.gson.JsonIOException

com.google.gson.JsonSyntaxException

parseResult

protected java.lang.Object parseResult(java.lang.Object result,
                                       java.lang.String id)
                                throws com.google.gson.JsonSyntaxException

Convert the JsonElement into the result object corresponding to the call made by id. If the result is already converted, does nothing.

Parameters:

result - json element to read from

id - id of request message this is in response to

Returns:

correctly typed object if the correct expected type can be determined, or result unmodified if no conversion can be done.

Throws:

com.google.gson.JsonSyntaxException

parseParams

protected java.lang.Object parseParams(com.google.gson.stream.JsonReader in,
                                       java.lang.String method)

                                       com.google.gson.JsonIOException

Convert the json input into the parameters object corresponding to the call made by method. If the method is not known until after parsing, call parseParams(Object, String) on the return value of this call for a second chance conversion.

Parameters:

in - json input to read from

method - method name of request

Returns:

correctly typed object if the correct expected type can be determined, or a JsonElement representing the parameters

Throws:

java.io.IOException

com.google.gson.JsonIOException
