Fabian Hueske commented on FLINK-1388:
--------------------------------------
Hi,
the PojoTypeInfo contains all information you need. Get the PojoFields like
{code}
int numFields = pType.getArity();
for(int i=0;i<numFields;i++) {
PojoField pField = pType.getPojoFieldAt(i);
}
{code}
The PojoField contains the reflection field {{pField.field}} which can be used
to extract the field like {{pFieldValue = pField.field.get(myPojo)}}.
Have a look at {{PojoSerializer.serialize()}} and {{PojoTypeInfo}}.
