Loop — Processes a message multiple times
The Loop pattern executes a series of processing steps multiple times. The number of times the loop runs is controlled by an expression.
The Loop pattern can occur anywhere in the body of a route.
Table 40 describes the properties you can specify using the properties editor.
Table 40. Loop Properties
| Name | Description |
|---|---|
| Language | Specifies the expression language used to process the expression. |
| Copy | Specifies whether the original message is copied into a new message. The default is Enabled. |
| Description | Specifies a text description for the node. This description is included in the generated XML file, but it is informational only. It is not used by Apache Camel. |
| Do While | Enables the While loop that loops until the predicate evaluates to false or null. The default is Disabled. |
| Id | Specifies a unique identifier for the endpoint. The tooling automatically generates an id for a node when it is created, but you can remove that id or replace it with your own. The Camel debugger requires all nodes with a breakpoint set to have a unique id. You can use the id to refer to endpoints in your Camel XML file. |
