| Field Summary | |
| final public static int | STATE_CONFIGURED
A constant defining that the package has been loaded and configured. | | final public static int | STATE_ERROR
A constant defining that the package produced an error and is not available. | | final public static int | STATE_INITIALIZED
A constant defining that the package was initialized and is ready to use. | | final public static int | STATE_NEW
A constant defining that the package is new. |
| Constructor Summary | |
| public | PackageState(Module module)
Creates a new package state for the given module. | | public | PackageState(Module module, int state)
Creates a new package state for the given module. |
| Method Summary | |
| public boolean | configure(SubSystem subSystem)
Configures the module and raises the state to STATE_CONFIGURED if the
module is not yet configured.
Parameters:
subSystem - the sub-system. | | public boolean | equals(Object o)
Compares this object with the given other object for equality. | | public Module | getModule()
Returns the module managed by this state implementation. | | public int | getState()
Returns the current state of the module. | | public int | hashCode()
Computes a hashcode for this package state. | | public boolean | initialize(SubSystem subSystem)
Initializes the contained module and raises the set of the module to
STATE_INITIALIZED, if the module was not yet initialized. |
| STATE_CONFIGURED | | final public static int STATE_CONFIGURED(Code) | | A constant defining that the package has been loaded and configured.
|
| STATE_ERROR | | final public static int STATE_ERROR(Code) | | A constant defining that the package produced an error and is not available.
|
| STATE_INITIALIZED | | final public static int STATE_INITIALIZED(Code) | | A constant defining that the package was initialized and is ready to use.
|
| STATE_NEW | | final public static int STATE_NEW(Code) | | A constant defining that the package is new.
|
| PackageState | | public PackageState(Module module)(Code) | | Creates a new package state for the given module. The module state will
be initialized to STATE_NEW.
Parameters:
module - the module. |
| PackageState | | public PackageState(Module module, int state)(Code) | | Creates a new package state for the given module. The module state will
be initialized to the given initial state.
Parameters:
module - the module.
Parameters:
state - the initial state |
| configure | | public boolean configure(SubSystem subSystem)(Code) | | Configures the module and raises the state to STATE_CONFIGURED if the
module is not yet configured.
Parameters:
subSystem - the sub-system. true, if the module was configured, false otherwise. |
| equals | | public boolean equals(Object o)(Code) | | Compares this object with the given other object for equality.
See Also: java.lang.Object.equals(java.lang.Object)
Parameters:
o - the other object to be compared true, if the other object is also a PackageState containingthe same module, false otherwise. |
| getModule | | public Module getModule()(Code) | | Returns the module managed by this state implementation.
the module. |
| getState | | public int getState()(Code) | | Returns the current state of the module. This method returns either
STATE_NEW, STATE_CONFIGURED, STATE_INITIALIZED or STATE_ERROR.
the module state. |
| initialize | | public boolean initialize(SubSystem subSystem)(Code) | | Initializes the contained module and raises the set of the module to
STATE_INITIALIZED, if the module was not yet initialized. In case of an
error, the module state will be set to STATE_ERROR and the module will
not be available.
Parameters:
subSystem - the sub-system. true, if the module was successfully initialized, false otherwise. |
