Method Detail

transform

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

Description copied from interface: PullTransformer

Transform source data into the result type.

Specified by:

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

Parameters:

source - The source data

context - The context for the transformation

Returns:

The transformed result

getSourceType

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

Specified by:

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

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<java.lang.Object,T>

Returns:

An integer representing the cost of the transformation

createElement

protected abstract T createElement(javax.xml.namespace.QName element,
                                   java.lang.String literal,
                                   TransformationContext context)

getSourceDataBinding

public java.lang.String getSourceDataBinding()

Description copied from interface: Transformer

Get the source type that this transformer transforms data from. The type is used as the key when the transformer is registered with TransformerRegistry.

Specified by:

getSourceDataBinding in interface Transformer

Overrides:

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

Returns:

A key identifying the source type
