Method Detail

getSourceType

protected abstract java.lang.Class<S> getSourceType()

getTargetType

protected abstract java.lang.Class<T> getTargetType()

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

Returns:

A key identifying the source type

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

Returns:

A key identifying the target type

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

Returns:

An integer representing the cost of the transformation
