public XML2JavaBeanTransformer()

Method Detail

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<T,java.lang.Object>

Returns:

An integer representing the cost of the transformation

transform

public java.lang.Object transform(T source,
                                  TransformationContext context)

Description copied from interface: PullTransformer

Transform source data into the result type.

Specified by:

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

Parameters:

source - The source data

context - The context for the transformation

Returns:

The transformed result

toJavaObject

public java.lang.Object toJavaObject(javax.xml.namespace.QName xmlType,
                                     T xmlElement,
                                     TransformationContext context)

getText

getTargetType

public java.lang.Class<java.lang.Object> getTargetType()

Specified by:

getTargetType in class BaseTransformer<T,java.lang.Object>

getTargetDataBinding

public java.lang.String getTargetDataBinding()

Description copied from interface: Transformer
