Hi,
I want to develope a user defined node for which the input will be in CSV(Comma Separated Values) format.
I wanted to know how can I access the values in CSV format inside user defined node and pass it to the output in the same CSV format. I am writing the node in C language.
Please help
Thanks in advance,
Prasanna |

If you are writing a user defined message processing node, then you access the logical tree the same as you would in ESQL or Java or PHP Compute nodes.
If you are writing a user defined input node, you associate the bitstream you have produced or acquired with the correct parser.
If you are writing a user defined output node, then you ask the parser to serialize the logical tree into a bitstream.
If you didn't understand any of that, go read everything under this link until you do. |

What will this node do that the built in functionality does not?
