Method Details

start

public void start()

Description copied from interface: HandlerContext

Starts this HandlerContext.

Specified by:

start in interface HandlerContext

stop

public void stop()

Description copied from interface: HandlerContext

Stops this HandlerContext.

Specified by:

stop in interface HandlerContext

invokeSingleUseHandlerAsync

public void invokeSingleUseHandlerAsync(Consumer<Object> success,
 Consumer<Throwable> failure,
 Attributes attributes,
 String module,
 String method,
 Object... args)

Description copied from interface: HandlerContext

Creates a Resource, invokes a method on that Resource, and returns the result as either a success or a failure. The HandlerContext will assign a temporary Path, and ResourceId which will not be exposed to the client code. Further, this will guaranteed the destruction of the created Resource even if the client abandons the call this method. The underlying HandlerContext may time out the Resource. In which case the caller will receive an instance fo HandlerTimeoutException through the returned Future or in the Consumer<Throwable> handed to the method.

Specified by:

invokeSingleUseHandlerAsync in interface HandlerContext

Parameters:

success - invoked when the invocation successfully returns

failure - invoked whent he invocation encounters an error

attributes - the Attributes supplied to the underlying Resource

module - the module name used to instantiate the resource

method - the method to invoke

args - the arguments passed to the method

invokeRetainedHandlerAsync

public void invokeRetainedHandlerAsync(Consumer<Object> success,
 Consumer<Throwable> failure,
 Attributes attributes,
 String module,
 String method,
 Object... args)

Description copied from interface: HandlerContext

Creates a Resource, invokes a method on that Resource, and returns the result as either a success or a failure. The HandlerContext will assign a temporary Path, and ResourceId which will not be exposed to the client code. Unlike HandlerContext.invokeSingleUseHandlerAsync(Consumer, Consumer, Attributes, String, String, Object...) this will just unlink the Resource after it invokes the specified method. It will be responsiblity of the invoked method to provide further retentions should it be desired. The underlying HandlerContext may time out the Resource. In which case the caller will receive an instance fo HandlerTimeoutException through the returned Future or in the Consumer<Throwable> handed to the method.

Specified by:

invokeRetainedHandlerAsync in interface HandlerContext

Parameters:

success - invoked when the invocation successfully returns

failure - invoked whent he invocation encounters an error

attributes - the Attributes supplied to the underlying Resource

module - the module name used to instantiate the resource

method - the method to invoke

args - the arguments passed to the method
