Method Detail

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

getTargetType

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

Specified by:

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

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

getText

protected abstract java.lang.String getText(T source)

Get the string value from the source

Parameters:

source -

Returns:

A string

close

protected void close(T source)

To be overrided by the subclass

Parameters:

source -

getTargetDataBinding

public java.lang.String getTargetDataBinding()

Description copied from interface: Transformer

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

Specified by:

getTargetDataBinding in interface Transformer

Overrides:

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

Returns:

A key identifying the target type
