Subject [jira] [Commented] (CAMEL-7995) Route model - Keep the {{ }} placeholders and allow api to get the model with the resolved values
Date Tue, 04 Nov 2014 20:44:54 GMT

    [ https://issues.apache.org/jira/browse/CAMEL-7995?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14196737#comment-14196737
] 

Grzegorz Grzybek commented on CAMEL-7995:
-----------------------------------------

Because Camel model (JAXB-based) elements (e.g. processor definitions) can have many String
properties which can be defined using placeholders (_templates_), to support marshalling to
XML (via JAXB) in two modes (with placeholders and with replaced values) we should actually
keep two {{*Definition}} objects because (for example) template values in {{ProcessorDefinition}}
are overriden when actual {{Processor}} instances are created.
Maybe processor definition could keep a copy if itself from the moment it was created (something
like instance‚Üítemplate relationship)?

Also there's inconsistency: {{ProcessorDefinition}} instances have there placeholder values
replaced with actual values when the {{Processor}} is created. But this is not the case for
{{FromDefinition}} which only provides it's (probably parameterized with placeholder) value
of {{uri}} in {{org.apache.camel.model.FromDefinition#resolveEndpoint()}}.

> When you define routes using {{ }} placeholders, they get resolved when Camel builds
the runtime route. And the route model gets updated with the resolved values, eg so {{ }}
gets replaced with the value.
> So when you dump the route model as xml (eg as source) then you loose the {{ }} placeholders
and see the actual values.
> We should allow to keep the {{ }} so the route model is 100% as designed, but we should
also store the resolved values that the runtime route is using, so you can see those values
as well.
