Class DataObject2NodeInfoTransformer

java.lang.Object
  org.apache.tuscany.sca.databinding.impl.BaseTransformer<DataObject,NodeInfo>
      org.apache.tuscany.sca.databinding.saxon.DataObject2NodeInfoTransformer

All Implemented Interfaces:

PullTransformer<DataObject,NodeInfo>, Transformer

public class DataObject2NodeInfoTransformer
extends BaseTransformer<DataObject,NodeInfo>
implements PullTransformer<DataObject,NodeInfo>

Transforms SDO DataObject-s to NodeInfo objects needed by Saxon parser. For root element when Serializing the DataObject the name of its implemented interface is used with its first letter made lowercase. Also any namespaces that are defined are deleted, because otherwise the SaxonB parser does not work

Method Detail

transform

public NodeInfo transform(DataObject source,
                          TransformationContext context)

Description copied from interface: PullTransformer

Transform source data into the result type.

Specified by:

transform in interface PullTransformer<DataObject,NodeInfo>

Parameters:

source - The source data

context - The context for the transformation

Returns:

The transformed result

getSourceType

protected java.lang.Class<DataObject> getSourceType()

Specified by:

getSourceType in class BaseTransformer<DataObject,NodeInfo>

getTargetType

protected java.lang.Class<NodeInfo> getTargetType()

Specified by:

getTargetType in class BaseTransformer<DataObject,NodeInfo>

getWeight

public int getWeight()

Description copied from interface: Transformer

Get the cost of the transformation. The weight can be used to choose the most efficient path if there are more than one available from the source to the target.

Specified by:

getWeight in interface Transformer

Overrides:

getWeight in class BaseTransformer<DataObject,NodeInfo>

Returns:

An integer representing the cost of the transformation
