*Available as of Camel version 2.15*

Camel-Atmos is an http://camel.apache.org/[Apache Camel] component that
allows you to work with ViPR object data services using the
https://github.com/emcvipr/dataservices-sdk-java[Atmos Client].

[source,java]

from("atmos:foo/get?remotePath=/path").to("mock:test");

== Options


// component options: START
The Atmos component supports 5 options, which are listed below.



[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *fullTokenId* (security) | The token id to pass to the Atmos client |  | String
| *secretKey* (security) | The secret key to pass to the Atmos client (should be base64 encoded) |  | String
| *uri* (advanced) | The URI of the server for the Atmos client to connect to |  | String
| *sslValidation* (security) | Whether the Atmos client should perform SSL validation | false | boolean
| *basicPropertyBinding* (advanced) | Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities | false | boolean
|===
// component options: END



// endpoint options: START
The Atmos endpoint is configured using URI syntax:

----
atmos:name/operation
----

with the following path and query parameters:

=== Path Parameters (2 parameters):


[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *name* | Atmos name |  | String
| *operation* | *Required* Operation to perform |  | AtmosOperation
|===


=== Query Parameters (14 parameters):


[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *localPath* (common) | Local path to put files |  | String
| *newRemotePath* (common) | New path on Atmos when moving files |  | String
| *query* (common) | Search query on Atmos |  | String
| *remotePath* (common) | Where to put files on Atmos |  | String
| *bridgeErrorHandler* (consumer) | Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. | false | boolean
| *exceptionHandler* (consumer) | To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored. |  | ExceptionHandler
| *exchangePattern* (consumer) | Sets the exchange pattern when the consumer creates an exchange. |  | ExchangePattern
| *lazyStartProducer* (producer) | Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. | false | boolean
| *basicPropertyBinding* (advanced) | Whether the endpoint should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities | false | boolean
| *synchronous* (advanced) | Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). | false | boolean
| *uri* (advanced) | Atomos server uri |  | String
| *fullTokenId* (security) | Atmos client fullTokenId |  | String
| *secretKey* (security) | The secret key to pass to the Atmos client (should be base64 encoded) |  | String
| *sslValidation* (security) | Atmos SSL validation | false | boolean

// spring-boot-auto-configure options: START
== Spring Boot Auto-Configuration

When using Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

[source,xml]
----
<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-atmos-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>
----


The component supports 6 options, which are listed below.



[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *camel.component.atmos.basic-property-binding* | Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities | false | Boolean
| *camel.component.atmos.enabled* | Enable atmos component | true | Boolean
| *camel.component.atmos.full-token-id* | The token id to pass to the Atmos client |  | String
| *camel.component.atmos.secret-key* | The secret key to pass to the Atmos client (should be base64 encoded) |  | String
| *camel.component.atmos.ssl-validation* | Whether the Atmos client should perform SSL validation | false | Boolean
| *camel.component.atmos.uri* | The URI of the server for the Atmos client to connect to |  | String
|===
// spring-boot-auto-configure options: END



== Dependencies

To use Atmos in your camel routes you need to add the dependency
on *camel-atmos* which implements this data format.

If you use maven you could just add the following to your pom.xml,
substituting the version number for the latest & greatest release (see
the download page for the latest versions).

[source,xml]
----------------------------------------------------------
<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-atmos</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

[[Atmos-Integrations]]

== Integrations

When you look at atmos integrations, there is one type of consumer, 
GetConsumer, which is a type of ScheduledPollConsumer. 

* `Get`

Whereas there are 4 types of producers which are 

* `Get` 
* `Del` 
* `Move`
* `Put`

== Examples

These example are taken from tests:

[source,java]
-------------------------------
from("atmos:foo/get?remotePath=/path").to("mock:test");
-------------------------------

Here, this is a consumer example.
`remotePath` represents the path from where the data will
be read and passes the camel exchange to regarding producer
Underneath, this component uses atmos client API for this and
every other operations.

[source,java]
-------------------------------
from("direct:start")
.to("atmos://get?remotePath=/dummy/dummy.txt")
.to("mock:result");
-------------------------------

Here, this a producer sample.
`remotePath` represents the path where the operations occur
on ViPR object data service. In producers, operations(`Get`,`Del`,
`Move`,`Put`) run on ViPR object data services and results are set 
on headers of camel exchange.

Regarding the operations, the following headers are set on camel
exhange

[source,java]
-------------------------------
DOWNLOADED_FILE, DOWNLOADED_FILES, UPLOADED_FILE, UPLOADED_FILES, FOUND_FILES, DELETED_PATH, MOVED_PATH;
