How to implement a customize decoder same as Mapping but return Integer?

[Rod Zhong]

Hi Smooks users.

I am wondering is there an example to show how to implement a customize decoder so i can reference? 

taking the Smooks document section Java Bean decoder "Mapping".  it accepts a string as input and return another mapped String as output. 

However, in my case, I need to accept String as input but return Integer. How can I achieve it?
<jb:decodParam name="Dublin">123</jb:decodeParam>

use the existed Mapping decoder it return 123 as string value "123". 

<jb:value property="name" decoder="Mapping" data="history/@warehouse"> <jb:decodeParam name="1">Dublin</jb:decodeParam> <jb:decodeParam name="2">Belfast</jb:decodeParam> <jb:decodeParam name="3">Cork</jb:decodeParam> </jb:value>

There's an example of a custom decoder in https://github.com/smooks/smooks-examples/blob/v1.0.5/model-driven-basic/smooks-config.xml#L62 . In your case, I suppose you can extend https://github.com/smooks/smooks/blob/v2.0.0-RC3/core/src/main/java/org/smooks/engine/converter/MappingTypeConverterFactory.java to return an integer instead of a string and register the extended type converter in your app as shown in https://github.com/smooks/smooks-examples/blob/ccb8e3d062738589f92402780cebd13fbf8009c8/model-driven-basic/src/main/resources/META-INF/services/org.smooks.api.converter.TypeConverterFactory .

Hope that helps.
