Hi,

this indicated which values from your XML will be inserted into your funciton

either one - value

from one context only - context

or all - queue

look into this link that explains about the same.

value ---> is a value for the input parameter. It may be a single value or multiple values.

Queue-----> it is an entire instance of XML message. That means, if you have duplicates of a node, all those contexts will be includedin Queue, which is passed to UDF.

Context -

---

> refers to a particular context of the XML message.

Please refer to the following document which comprehensively explain differences b/w the various options with examples

There r 2 types of UDF - Simple and Advanced- Simple UDFs uses Value, wherein we can manipulate only one value (input is one String). Therefore a single string is expected as input and the output would also b a single string.

Advanced UDFs uses Context or Queue, where you manipulate many values (input is an array of Strings).

This will help u
