SequenceTransformation

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: true false
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:

• Description
• TransformationAlias
• SequenceElement

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.

How To

SequenceTransformation with VulCon

To create a SequenceTransformation with VulCon^® go to the Core View and perform the following steps:

1. Under the Transformations element, create the transformations you want to be executed
2. Create a new SequenceTransformation element and set name and output attributes. You may also set the optional attributes validate and DumpInOut.
3. 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.
