Hi ! Gabriel

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

either one - value

from one context only - context

or all - queue

<b>look into this link that explains about the same.</b>

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

<b>There r 2 types of UDF - Simple and Advanced</b>- 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

Hi

Context - It donot have identifiable context change.

Queue - Contains context change indicator and it is much more memory intensive.

Working functionalities are same.
