org.apache.tuscany.sca.databinding.saxon
Class NodeInfo2DataObjectTransformer

java.lang.Object
  org.apache.tuscany.sca.databinding.impl.BaseTransformer<NodeInfo,DataObject>
      org.apache.tuscany.sca.databinding.saxon.NodeInfo2DataObjectTransformer

All Implemented Interfaces:

PullTransformer<NodeInfo,DataObject>, Transformer

public class NodeInfo2DataObjectTransformer
extends BaseTransformer<NodeInfo,DataObject>
implements PullTransformer<NodeInfo,DataObject>

Transforms NodeInfo objects to SDO DataObjects. Before constructing the data object, resulting XML is populated with correct namespaces (which are taken from the logical target data type) These namespaces are crucial for constructing the right instance of the DataObject (i.e. if there is a SDO factory, an instance from this factory will be used, not the generic any data object)

Constructor Summary

Method Summary

protected java.lang.Class<NodeInfo>	getSourceType()
protected java.lang.Class<DataObject>	getTargetType()
int	getWeight() Get the cost of the transformation.
DataObject	transform(NodeInfo source, TransformationContext context) Transform source data into the result type.

Method Detail

getSourceType

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

Specified by:

getSourceType in class BaseTransformer<NodeInfo,DataObject>

getTargetType

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

Specified by:

getTargetType in class BaseTransformer<NodeInfo,DataObject>

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<NodeInfo,DataObject>

Returns:

An integer representing the cost of the transformation

transform

public DataObject transform(NodeInfo source,
                            TransformationContext context)

Description copied from interface: PullTransformer

Transform source data into the result type.

Specified by:

transform in interface PullTransformer<NodeInfo,DataObject>

Parameters:

source - The source data

context - The context for the transformation

Returns:

The transformed result
