connect

public void connect(SourceWireFactory sourceFactory,
                    TargetWireFactory targetFactory,
                    java.lang.Class targetType,
                    boolean downScope,
                    ScopeContext targetScopeContext)
             throws BuilderConfigException

Description copied from interface: WireBuilder

Connects wire configurations of the source proxy factory to corresponding ones in the target proxy to factory

Specified by:

connect in interface WireBuilder

Parameters:

sourceFactory - the proxy factory used in constructing the source side of the wire chain

targetFactory - the proxy factory used in constructing the target side of the wire chain

targetType - the context type of the target. Used to determine if a paricular wire builder should construct the wire

downScope - true if the component containing the reference (source side) is of a lesser scope than the target service

targetScopeContext - the scope context responsible for managing intance contexts of the target component type

Throws:

BuilderConfigException - if an error occurs during the wire buildSource process

completeTargetChain

public void completeTargetChain(TargetWireFactory targetFactory,
                                java.lang.Class targetType,
                                ScopeContext targetScopeContext)
                         throws BuilderConfigException

Description copied from interface: WireBuilder

Finishes processing the target side wire chain. For example, a TargetInvoker used by target-side proxies is usually set during this phase.

Specified by:

completeTargetChain in interface WireBuilder

Parameters:

targetFactory - the target-side proxy factory

targetType - the target context type

targetScopeContext - the target scope

Throws:

BuilderConfigException - if an error occurs during the wire buildSource process

createInvoker

protected abstract TargetInvoker createInvoker(QualifiedName targetName,
                                               java.lang.reflect.Method operation,
                                               ScopeContext context,
                                               boolean downScope)

Callback to create the specific TargetInvoker type for dispatching to the target type

Parameters:

targetName - the fully qualified name of the wire target

operation - the operation the invoker will be associated with

context - the scope context that manages the target context

downScope - whether the wire source scope is "longer" than the target
