Method Summary

InstanceWrapper	createInstanceWrapper() Create a wrapper for the component instance for the scope management
Invoker	createInvoker(RuntimeComponentService service, Operation operation) Create an invoker for the component implementation in the invocation chain.
long	getMaxAge()
long	getMaxIdleTime()
Scope	getScope() Get the scope for the component implementation
boolean	isEagerInit() Indicate if the component needs to be eagerly initialized
void	start() This method will be invoked when the component implementation is activated.
void	stop() This method will be invoked when the component implementation is deactivated.
boolean	supportsOneWayInvocation() For bindings that invoke one-way callback operations asynchronously, there is no need to perform a thread switch before calling the invoker.

Method Detail

createInvoker

public Invoker createInvoker(RuntimeComponentService service,
                             Operation operation)

Description copied from interface: ImplementationProvider

Create an invoker for the component implementation in the invocation chain. The invoker will be responsible for calling the implementation logic for the given component.

Specified by:

createInvoker in interface ImplementationProvider

Parameters:

service - The component service

operation - The operation that the interceptor will handle

Returns:

An invoker that handles the invocation logic, null should be returned if no invoker is required

supportsOneWayInvocation

public boolean supportsOneWayInvocation()

Description copied from interface: ImplementationProvider

For bindings that invoke one-way callback operations asynchronously, there is no need to perform a thread switch before calling the invoker. This method indicates whether the binding has this capability.

Specified by:

supportsOneWayInvocation in interface ImplementationProvider

Returns:

true if the callback invoker is able to invoke one-way operations asynchronously, false if all invocations are synchronous

getScope

public Scope getScope()

Description copied from interface: ScopedImplementationProvider

Get the scope for the component implementation

Specified by:

getScope in interface ScopedImplementationProvider

Returns:

The scope for the component implementation, if null is returned, STATELESS will be used

start

public void start()

Description copied from interface: ImplementationProvider

This method will be invoked when the component implementation is activated.

Specified by:

start in interface ImplementationProvider

stop

public void stop()

Description copied from interface: ImplementationProvider

This method will be invoked when the component implementation is deactivated.

Specified by:

stop in interface ImplementationProvider

createInstanceWrapper

public InstanceWrapper createInstanceWrapper()

Description copied from interface: ScopedImplementationProvider

Create a wrapper for the component instance for the scope management

Specified by:

createInstanceWrapper in interface ScopedImplementationProvider

Returns:

A wrapper for the component instance

isEagerInit

public boolean isEagerInit()

Description copied from interface: ScopedImplementationProvider

Indicate if the component needs to be eagerly initialized

Specified by:

isEagerInit in interface ScopedImplementationProvider

Returns:

true if the component is marked to be eagerly initialized, false otherwise

getMaxAge

public long getMaxAge()

Specified by:

getMaxAge in interface ScopedImplementationProvider

Returns:

the maxAge

getMaxIdleTime

public long getMaxIdleTime()

Specified by:

getMaxIdleTime in interface ScopedImplementationProvider

Returns:

the maxIdleTime
