Table 40. Loop Properties

NameDescription
LanguageSpecifies the expression language used to process the expression.
CopySpecifies whether the original message is copied into a new message. The default is Enabled.
DescriptionSpecifies 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 WhileEnables 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.
