Aggregate component

The Aggregate component aggregates multiple incoming messages to one single message.

Configuration

The Aggregate component has the following configuration options:

Property	Description
File Type	The type of the files that are aggregated together. Currently the Aggregate component only supports XML and JSON files.
Completion Count	The amount of messages the aggregate component should aggregate before sending them to the next component.
Completion Count Timeout	The timeout in miliseconds for the Completion Count option. This is the amount of time the component should wait before the count is reached. The timeout starts when the component is inactive and resets when it becomes active again.
Completion Interval	The amount of miliseconds the aggregate component should wait before sending the aggregated message to the next component.

Remarks

• For XML aggregation the component creates a new root element named Aggregate to produce a valid XML file.
• For XML aggregation use of valid XML file is necessary. It is important to escape invalid characters in the text of the XML elements. These are the invalid XML characters and their escaped equivalents:
  • < has to be <
  • > has to be >
  • & has to be &

Examples

When the Completion Count would be set on 2 and the flow would receive 4 single XML files the result would look like this:
