Description
SequenceTransformation element defines a series of Transformation to be executed.
GreenVulcano® ESB Configuration
SequenceTransformation is used by element Transformations.
The following table shows its attributes:
| Attribute | Type | Description |
|---|---|---|
| type | fixed | This attribute must assume the value transformation. |
| class | fixed | This attribute must assume the value it.greenvulcano.gvesb.gvdte.controller.SequenceTransformer |
| name | required | Transformation name.
The attribute's value cannot be null. |
| Output | required | The name of the object to be returned to the caller.
Must be the name of the output or buffer field of any sequence's base transformation. |
| validate | optional | The attribute's admitted values are:
|
| DumpInOut | optional | If true enables the dump of the input/output data at every transformation step.
Default false. |
SequenceTransformer might contain the following sub-elements:
SequenceElement
The SequenceElement Element is used by SequenceTransformation.
The following table shows its attributes:
| Attribute | Type | Description |
|---|---|---|
| Transformer | required | Name of a base transformation. |
| Input | required | Name of the input object.
The attribute's value cannot be null. |
| Output | required | Name of the output object.
The attribute's value cannot be null. |
| Buffer | optional | Name of the buffer object.
The object data an be modified by the current transformation. The attribute's value cannot be null. |
Might contain the following sub-element:
How To
To create a SequenceTransformation with VulCon® go to the Core View and perform the following steps:
- Under the Transformations element, create the transformations you want to be executed
- Create a new SequenceTransformation element and set name and output attributes. You may also set the optional attributes validate and DumpInOut.
- Add the SequenceElement elements, one for each transformation, and set its attributes.
The picture shows the VulCon configuration of the SequenceTransformation InsertCampaignDataSeq.
<SequenceTransformation Output="OUT2"
class="it.greenvulcano.gvesb.gvdte.controller.SequenceTransformer"
name="InsertCampaignDataSeq" type="transformation">
<SequenceElement Input="IN" Output="OUT1" Transformer="AddXMLTag"/>
<SequenceElement Input="OUT1" Output="OUT2" Transformer="InsertCampaignData"/>
</SequenceTransformation>
This sequence performs the AddTagTransformation AddXMLTag and the XSLTransformation InsertCampaignData.
