public class Component
extends DrclObj

Component is the base class for implementing components in the Autonomous Component Architecture (ACA).

A component in ACA is analogous to an IC chip in digital circuit design. As pins to an IC chip, ports are the only means with which a component is interfaced with the rest of the system. And as the specification in a data cookbook in digital circuit desgin, a component is fully specified by contracts. A contract describes how a a component expects and responds what format of data to arrive and send at which ports.

When data arrives at a component, a new thread is spawned and carries out the process() method to process the data at the component. The data processing must follow the contract(s) that are obtained by getContract(Port). There are a rich set of data structures and methods defined in a component. Some of which are facilities that facilitate using a component in a system. Some of which are methods defined in ACA which a subclass must implement. Some of which are API's that writing a component subclass may take advantage of. All these are categorized and described as follows:

Component hierarchy:
A component may act as a container and contain other components to form a component hierarchy. Use the set of addComponent() and removeComponent() methods to manipulate the component hierarchy.
Creating/removing ports:
Use the set of addPort() and removePort() methods, or use specialized methods (addEventPort(String), addForkPort(String), addServerPort(String)) to create ports in defined port groups.
System operation: reboot() to reset the component hierarchy and the associated runtime.
ActiveComponent operations: One may use (1) run() to start all the ActiveComponents under this component hierarchy; (2) stop() to stop all the ActiveComponents under this component hierarchy; and (3) resume() to resume all the ActiveComponents under this component hierarchy. The operate() method provides a unified and general form of the above three operations.
An ActiveComponent subclass should implement _start(), _stop() and _resume() to make these operations work.
Utility methods: A component subclass must implement (1) reset() to reset this component to the initial state; (2) duplicate(Object) to duplicate the contents of another component; and (3) info() to provide the current states of this component for varifying the operations of this component at run-time.
The information port (infoport): every component is equipped with an infoport. A component may export different types of messages at this port:
- Error message: An error message is exported when some error occurs in processing some data. Subclasses should use one of the error() methods to send out an error message.
- Garbage message: A garbage message is exported when data is unwanted and discarded by the component due to the component's capacity or defined policy. Subclasses should use one of the drop() methods to send out a garbage message.
- Trace message: A trace message is exported when data arrives or is sent out at a port. Exports of trace messages are implemented in the base class. Subclasses do not need to send out such messages.
- Debug message: Subclasses may export debug messages whenever appropriate to facilitate diagnosing an erroneous component. Subclasses should use debug(Object) to send out a debug message.

A 64-bit "register": The register contains (i) flags that control export of different types of messages at infoport and event ports. (ii) ActiveComponent states, and (iii) debug level bits, each of which can be used to enable/disable export of debug messages at a debug level.

Debug Levels

(unused)

DOE

GDE

The flags are described in the following table.

FLAG	FLAG NAME	DESCRIPTION
E	Enabled	If disabled, the component does not respond to any arriving data. Default is enabled.
EE	ErrorEnabled	If disabled, the component suppresses `error messages` being sent out. Default is enabled.
GE	GarbageEnabled	If disabled, the component suppresses `garbage messages` being sent out. Default is disabled.
GDE	GarbageDisplayEnabled	The displayable flag of the `garbage messages` being sent out is set to the value of this flag. Default is disabled.
DE	DebugEnabled	If disabled, the component suppresses `debug messages` being sent out. Default is disabled.
TE	TraceEnabled	If disabled, the component suppresses `trace messages` being sent out. Default is disabled.
VE	EventEnabled	If disabled, the component suppresses `event messages` being sent out. Default is enabled.
CN	ComponentNotification	If enabled, `componentAdded(Component)`/`componentRemoved(Component)` is invoked whenever a component is added in/removed from this component. Default is disabled.
PN	PortNotification	If enabled, `portAdded(Port)`/`portRemoved(Port)` is invoked whenever a port is added to/removed from this component. Default is disabled.
DOE	DirectOutputEnabled	If enabled, all the above messages are sent to standard output directly instead of being sent out at `infoport`. Default is disabled.
ST	Started	This flag is set if this component is started as `ActiveComponent` (see `run()`). It is reset when the component is reset (`reset()`). This flag is effective only if this component is an `ActiveComponent`.
SP	Stopped	This flag is set if the component is stopped (by `stop()`) and has not been resumed (`resume()`). The flag is reset if the component is reset (`reset()`) or resumed (`resume()`). This flag is effective only if this component is an `ActiveComponent`.

Each flag can be tested/set with the pair of the corresponding getter and setter methods. For example, use isDebugEnabled() to check if the debug flag is set, and setDebugEnabled(boolean) to enable/disable the debug flag of this component.
The higher 32 bits of the register are undefined. Subclasses may define their own flags on those bits.

Debug levels: A subclass may classify its debug messages into debug levels. One may use one of setDebugEnabledAt()/isDebugEnabledAt() to control/check export of debug messages of a debug level. Debug levels are only valid when the debug flag is enabled. To make the above methods usable, a subclass must implement getDebugLevelNames().
Component/port added notification: To enable either one, a subclass should use setComponentNotificationEnabled(boolean) or setPortNotificationEnabled(boolean) and then implement componentAdded(Component)/componentRemoved(Component) or portAdded(Port)/portRemoved(Port).
APIs for writing a subclass: getTime(), time control (sleepFor(double), sleepUntil(double)), mutex (lock(Object), unlock(Object)), synchronization (wait(Object), notify(Object), notifyAll(Object)), fork events (fork(Port, Object, double), forkAt(Port, Object, double), send(Port, Object, double), sendAt(Port, Object, double), and cancelFork(ACATimer)), binding contracts (setContract(Class, String, Contract)).
