The Route function processor-type Function can be used to apply different conditions on how data is handled to the data handling depending on the its value. This is a processor. It is recommended that the configuration be completed before connecting other processors or forwarders. The order in which each condition is added is the order in which each condition is applied to the input.

When multiple conditions are added to the Route functionFunction, you can re-order any condition by drag and drop method using the the Image Modified icon on the Condition box.

To configure the Route functionFunction, the following is required:

Field	Description
Field	The input from the

function

Function preceding the Route function

node

in the stream. You can

either customize

select the

input

field

or select from the predefined options

from the drop-down list or type the field into the Add field box and click the + button.

Expression

The mathematical conditions to compare values and expressions. The available conditions are:

Less than
Equal to
Not equal to
Greater than
List lesser than
List equal to
List greater than
Regexp

Value

The value that you want to enter for the condition.

For the Route function to import the data from the preceding function(s) connected to it, a preview must be generated.

To generate a preview, take the following steps for configuring the condition(s):

In Field, select an option from the drop-down list which is populated with the input from the function preceding the Route function in your stream.
In Expression, specify the condition or if you select Regexp, enter the regular expression that you want to apply in Value. Standard regular expressions are supported.
In Value, specify the value or the regular expression depending on the function preceding the Route function.
To add a new condition, you can click the +New Condition button.

...

Note!

Data is checked for matching against each condition only in the order in which the conditions are arranged in the configuration.

...

For example, if the data matches the first condition, it is sent via the Output that you enter for that condition. If the data does not match with the first condition, it is checked to match against the second condition or the third condition, and so on.
If the data checked for matching in two or more conditions overlap, then the condition that is first in the order is considered.

Some examples for of using the RegexpRegexp option in Expression:

Info

Examples - Using regexp

If you have the following input:

Code Block
shipment cost cost of shipment Shipment cost: SHIPMENT

When you enter shipment, the result is:

Code Block
shipment cost => true cost of shipment => true Shipment cost: => false SHIPMENT => false

When you enter [Ss]hipment, the result is:

Code Block
shipment => true Shipment => true Shipment cost: => true SHIPMENT => false

[a-zA-Z] - Matches all lowercase and uppercase letters

\w+ - Matches any word character (alphanumerical or underscore) with at least one length

The Route function Function also enables you to be able to handle data that is not matched with any of the conditions that you might have configured. In In Handling of unmatched records, the available options are:

Discard: Discards the unmatched data
Create new output: Creates a new output with the name default
and
and adds it to the Route
function
Function in the stream editor.
