Transform Data Type

Camel supports the Message Translator from the EIP patterns.

How can systems using different data formats communicate with each other using messaging?

image

Use a special filter, a Message Translator, between other filters or applications to translate one data format into another.

The Message Translator can be done in different ways in Camel:

  • Using Transform or Set Body in the DSL

  • Calling a Processor or bean to perform the transformation

  • Using template-based Components, with the template being the source for how the message is translated

  • Messages can also be transformed using Data Format to marshal and unmarshal messages in different encodings.

  • Using data type based transformation using Transform DataType

This page is documenting the last approach by using Transform Data Type EIP.

Options

The Transform Data Type eip supports 0 options, which are listed below.

Name Description Default Type

note

Sets the note of this node.

String

description

Sets the description of this node.

String

disabled

Disables this EIP from the route.

false

Boolean

fromType

From type used in data type transformation.

String

toType

Required To type used as a target data type in the transformation.

String

Exchange properties

The Transform Data Type eip has no exchange properties.

Using Transform DataType EIP

The Transform DataType references a given from/to data type (org.apache.camel.spi.DataType).

  • Java

  • XML

  • YAML

from("direct:cheese")
    .transformDataType("myDataType")
    .to("log:hello");
<route>
    <from uri="direct:cheese"/>
    <transformDataType toType="myDataType"/>
    <to uri="log:hello"/>
</route>
- from:
    uri: direct:cheese
    steps:
      - transformDataType:
          toType: myDataType
      - to:
          uri: log:hello

The example above defines the Transform DataType EIP that uses a target data type myDataType. The given data type may reference a Transformer that is able to handle the data type transformation.

Users may also specify fromType in order to reference a very specific transformation from a given data type to a given data type.
