Reflection for Type structure

[pbmi]

Hi

I would like to get the metadata for a Type() structure, eg Field Count, FieldNames, FieldTypes, etc.

Is this possible with the Reflection library? Or is there another solutions.

Thanks

Type structures are regular Java classes. However Reflection library doesn't include methods to find this data.

Why do you need to find these values?

I want to build an abstract user input panel routine to use with many different user Types.

For example:

' get fieldcount, fieldnames from reflection on Type xxxz

Dim sv as scrollview

for I=0 to fieldcount

Dim line as horizontalscrollview
..

Dim lbl as label
..
lbl.text9=fieldnames(i)

line.panel.addview(label,..

Dim txt as edittext
..

line.panel.addview(txt,..

sv.panel.addview(line,..

next

Using Reflection for custom type

Type structures are regular Java classes. However Reflection library doesn't include methods to find this data.

It will be extremely usefull in order to serialize/deserialize json object retrieved or sended to WService into/from a custom type ( waiting for user classes in next releases )

Note that you can already serialize types with RandomAccessFile.WriteObject.

Does now! Given an object instance you can now pick up its Class instance using getClass() and reflect on that.

Great!

Many thanks for this. Will test this out asap...

json to type, type to json

Thank for your replay Erel. But what is the best way to convert a json from an httpresult into a custom type object?

There is no automatic way. You will need to write a Sub that reads the fields and assigns them to the Type values.

With v2.00 you will be able to do it with a class.
