Field Detail

component

protected IInternalAccess component

The component.

cinfo

protected ComponentCreationInfo cinfo

The creation info.

guesser

protected jadex.commons.IParameterGuesser guesser

The parameter guesser.

Constructor Detail

AbstractComponentFeature

protected AbstractComponentFeature(IInternalAccess component,
                                   ComponentCreationInfo cinfo)

Factory method constructor for instance level.

Method Detail

getInternalAccess

public IInternalAccess getInternalAccess()

Get the component access.

getComponent

public PlatformComponent getComponent()

Get the component access.

init

public jadex.commons.future.IFuture<java.lang.Void> init()

Initialize the feature. Empty implementation that can be overridden.

Specified by:

init in interface IComponentFeature

body

public jadex.commons.future.IFuture<java.lang.Void> body()

Execute the main activity of the feature.

Specified by:

body in interface IComponentFeature

hasUserBody

public boolean hasUserBody()

Check if the feature potentially executed user code in body. Allows blocking operations in user bodies by using separate steps for each feature. Non-user-body-features are directly executed for speed. If unsure just return true. ;-)

Specified by:

hasUserBody in interface IComponentFeature

shutdown

public jadex.commons.future.IFuture<java.lang.Void> shutdown()

Shutdown the feature.

Specified by:

shutdown in interface IComponentFeature

kill

public void kill()

Kill is only invoked, when shutdown of some (e.g. other) feature does not return due to timeout. The feature should do any kind of possible cleanup, but no asynchronous operations.

Specified by:

kill in interface IComponentFeature

getExternalFacade

public <T> T getExternalFacade(java.lang.Object context)

Get external feature facade.

getExternalFacadeType

public <T> java.lang.Class<T> getExternalFacadeType(java.lang.Object context)

getValueFetcher

public jadex.commons.IValueFetcher getValueFetcher()

The feature can inject parameters for expression evaluation by providing an optional value fetcher. The fetch order is the reverse init order, i.e., later features can override values from earlier features.

Specified by:

getValueFetcher in interface IComponentFeature

getParameterGuesser

public jadex.commons.IParameterGuesser getParameterGuesser()

The feature can add objects for field or method injections by providing an optional parameter guesser. The selection order is the reverse init order, i.e., later features can override values from earlier features.

Specified by:

getParameterGuesser in interface IComponentFeature

getClockService

public IClockService getClockService()

Get the clock service.

Returns:

The clock service.

getExecutionService

public IExecutionService getExecutionService()

Get the execution service.

Returns:

The execution service.
