Method Detail

open

public int open()

Description copied from interface: nxm.sys.inc.Commandable

This will prepare the commandable object for processing. This method must be called prior to calling Commandable.process() and should be used to open any files needed and to initialize any parameters.

Specified by:

open in interface nxm.sys.inc.Commandable

Overrides:

open in class nxm.sys.lib.Command

Returns:

• Commandable.NOOP if this method does no work.
• Commandable.NORMAL if this method successfully completes and the Commandable object is ready to be processed with Commandable.process().
• Commandable.FINISH if this method successfully completes and the Commandable object does not require any processing with Commandable.process() (i.e. skip directly to Commandable.close()).

See Also:

Commandable.process(), Commandable.close(), State Diagram for a Commandable Object

process

public int process()

Description copied from interface: nxm.sys.inc.Commandable

This will process the commandable objects algorithm. The Commandable.open() method will always be called before this method. This should be responsible for doing any of the data processing required by the commandable object.

If the commandable object requires multiple processing cycles it will return Commandable.NORMAL or Commandable.NOOP.

Specified by:

process in interface nxm.sys.inc.Commandable

Overrides:

process in class nxm.sys.lib.Command

Returns:

• Commandable.NORMAL upon completion of a single pass of the algorithm.
• Commandable.FINISH upon successful completion of the entire algorithm.
• Commandable.NOOP upon completion of a single pass of the algorithm in which no work was performed (this usually indicates that the object is waiting for another thread to provide data to process).
• Commandable.SLEEP upon completion of a single pass of the algorithm where a pause (see Time.sleep(double)) is required before Commandable.process() can be called again.
• Commandable.PAUSE or Commandable.SUSPEND indicates that the Commandable object should be placed in the Commandable.SUSPEND state until the Commandable.RESUME directive is given.

Time.sleep(double), Commandable.open(), Commandable.close(), State Diagram for a Commandable Object

close

public int close()

Description copied from interface: nxm.sys.inc.Commandable

This will finish the commandable objects processing. This method is to be used to "clean up" after running Commandable.open() and Commandable.process(); this includes closing any files opened by Commandable.open() and clearing any temporary data used by Commandable.process(). This is the stage where the commandable object would typically perform any final reporting of data (such as the setting of RESULTS parameters).

Specified by:

close in interface nxm.sys.inc.Commandable

Overrides:

close in class nxm.sys.lib.Command

Returns:

• Commandable.NOOP if this method does no work.
• Commandable.NORMAL if this method successfully completes.

getNextLink

public java.lang.Object getNextLink()

Description copied from interface: nxm.sys.inc.Chainable

Get the next object down the chain.

Specified by:

getNextLink in interface nxm.sys.inc.Chainable

Returns:

The next object down the chain.

See Also:

Chainable.getPrevLink()

getPrevLink

public java.lang.Object getPrevLink()

Description copied from interface: nxm.sys.inc.Chainable

Get the next object up the chain.

Specified by:

getPrevLink in interface nxm.sys.inc.Chainable

Returns:

The next object up the chain.

Chainable.getNextLink()
