Interface TransformerInterceptorFactory

public interface TransformerInterceptorFactory

Creates interceptors that transform input and output parameters from one format to another, e.g. DOM to Java or vice versa.

Method Summary

Modifier and Type	Method and Description
Interceptor	createInterceptor(PhysicalOperation operation, java.util.List<org.fabric3.api.model.type.contract.DataType> sources, java.util.List<org.fabric3.api.model.type.contract.DataType> targets, java.lang.ClassLoader targetLoader, java.lang.ClassLoader sourceLoader) Creates a transforming interceptor for a service operation.

Method Detail

createInterceptor

Interceptor createInterceptor(PhysicalOperation operation,
                              java.util.List<org.fabric3.api.model.type.contract.DataType> sources,
                              java.util.List<org.fabric3.api.model.type.contract.DataType> targets,
                              java.lang.ClassLoader targetLoader,
                              java.lang.ClassLoader sourceLoader)
                       throws org.fabric3.api.host.Fabric3Exception

Creates a transforming interceptor for a service operation. The interceptor converts input parameters from a source to a target type and output parameters from a target to a source type. The source and target types are selected from the list of supported source and target types based on order of preference (the source and target types are sorted in descending order) and the availability of a transformer.

Parameters:

operation - the operation to create the interceptor for

sources - the source types in descending order of preference

targets - the supported target types, in descending order of preference

targetLoader - the target service contribution classloader

sourceLoader - the source component contribution classloader

Returns:

the transforming interceptor

Throws:

org.fabric3.api.host.Fabric3Exception - if there is an error creating the interceptor such a transformer not being available for any of the source-target type combinations
