Interface TransformerFactory

public interface TransformerFactory

Creates a transformer capable of converting a set of classes from a source to target data type.

Method Summary

Modifier and Type	Method and Description
boolean	canTransform(org.fabric3.api.model.type.contract.DataType source, org.fabric3.api.model.type.contract.DataType target) Returns true if the factory creates transformers that can convert from the source to target data types.
Transformer<?,?>	create(org.fabric3.api.model.type.contract.DataType source, org.fabric3.api.model.type.contract.DataType target, java.util.List<java.lang.Class<?>> inTypes, java.util.List<java.lang.Class<?>> outTypes) Creates a transformer capable of converting from the source to target data types.
int	getOrder() Returns a value for ordering transformers.

Method Detail

getOrder

int getOrder()

Returns a value for ordering transformers. Higher values signify less weight;

Returns:

an ascending value where 0 is first

canTransform

                        java.util.List<java.lang.Class<?>> outTypes)
                 throws org.fabric3.api.host.Fabric3Exception

Creates a transformer capable of converting from the source to target data types.

Parameters:

source - the source data type

target - the target data type

inTypes - the physical types of the source data

outTypes - the physical types of the converted data

Returns:

the transformer the transformer

Throws:

org.fabric3.api.host.Fabric3Exception - if there was an error creating the transformer
