Subject: Re: recommendation requested: json translation into objects
What recommendation do people have for converting json syntax to an object?
Should I grab a library? If so, any suggestions on which one?
If it is a bean, you can use JSONSerializer. See
org.apache.pivot.tests.JSONBeanTest for an example.
>>>Hmm.looked at the JSONSerializer again. I think it can work. I looked at
the test, but my needs are from a JSON string to an object. The test showed
the object to string version. Based on your suggestion, I would need
something like below. I'll see how robust this is over time. Thanks!
BeanAdapter ba = new BeanAdapter(myObject);
theMap = JSONSerializer.toMap(myJsonSTring)
ba.putAll(theMap)
Ideally, I could register my converter and it gets called automatically when
I indicate the need for a conversion to a certain type.
Generally, we handle this by providing a string setter that performs the
conversion and calls the typed setter.
>>>Yup. I do this. On a separate note, this is also a motivation for
potentially recommending a PivotStyle annotation so I can find all the
styles more easily. If multiple getters exist, its difficult to
programmatically scan and dedup and know the true style object
type-something useful for tooling. I still have to read javadoc to get
styling information.
