Class ItemList2ObjectTransformer

java.lang.Object
  org.apache.tuscany.sca.databinding.impl.BaseTransformer<ItemList,java.lang.Object>
      org.apache.tuscany.sca.databinding.saxon.ItemList2ObjectTransformer

All Implemented Interfaces:

PullTransformer<ItemList,java.lang.Object>, Transformer

public class ItemList2ObjectTransformer
extends BaseTransformer<ItemList,java.lang.Object>
implements PullTransformer<ItemList,java.lang.Object>

Transforms each object contained in the ItemList object. If the object type is the same as the target type, it is not transformed. If the object is a NodeInfo, it's transformed to a DataObject. If the object is a Value, it's transformed to a Java object. If the target type is not an array, the first transformed object is returned. If the first transformed object type is not a target type, then a TransformException is thrown If the target type is an array, a array of this type is created containing all transformed objects and it is returned If any transformed object is not a target type, then a TransformException is thrown

Specified by:

getWeight in interface Transformer

Overrides:

getWeight in class BaseTransformer<ItemList,java.lang.Object>

Returns:

An integer representing the cost of the transformation

transform

Description copied from interface: PullTransformer

Transform source data into the result type.

Specified by:

transform in interface PullTransformer<ItemList,java.lang.Object>

Parameters:

source - The source data

context - The context for the transformation

Returns:

The transformed result
