Class CvValue

java.lang.Object
  jmri.jmrit.symbolicprog.AbstractValue
      jmri.jmrit.symbolicprog.CvValue

All Implemented Interfaces:

EventListener, ProgListener

public class CvValue
extends AbstractValue
implements ProgListener

Encapsulate a single CV value and provide programming access to the decoder.

Since this is a single CV in a single decoder, the Programmer used to get access is part of the state. This allows us to specify a specific ops-mode programmer aimed at a particular decoder.

There are three relevant parameters: Busy, Value, State. Busy == true means that a read or write operation is going on. When it transitions to "false", the operation is complete, and the Value and State are stable. During a read operation, Value changes before State, so you can assume that Value is stable if notified of a State change.

               Programmer pProgrammer)

Method Detail

toString

public String toString()

Overrides:

toString in class Object

number

public int number()

cvName

public String cvName()

piCv

public int piCv()

piVal

public int piVal()

siCv

public int siCv()

siVal

public int siVal()

iCv

public int iCv()

getValue

public int getValue()

notifyValueChange

protected void notifyValueChange(int value)

setValue

public void setValue(int value)

Edit a new value into the CV. Only use this for external edits, e.g. set form a GUI, not for internal uses, as it sets the state to EDITED

getDecoderValue

public int getDecoderValue()

Get the decoder value read during compare

Returns:

_decoderValue

getState

public int getState()

setState

public void setState(int state)

Set state value and send notification. Also sets GUI color as needed.

isBusy

public boolean isBusy()

setReadOnly

public void setReadOnly(boolean is)

Set bean keeping track of whether this CV is intended to be read-only. Does not otherwise affect behaviour! Default is "false".

getReadOnly

public boolean getReadOnly()

Retrieve bean keeping track of whether this CV is intended to be read-only. Does not otherwise affect behaviour! Default is "false".

setInfoOnly

public void setInfoOnly(boolean is)

Set bean keeping track of whether this CV is intended to be used as info-only. Does not otherwise affect behaviour! Default is "false".

getInfoOnly

public boolean getInfoOnly()

Retrieve bean keeping track of whether this CV is intended to be used as info-only. Does not otherwise affect behaviour! Default is "false".

setWriteOnly

public void setWriteOnly(boolean is)

Set bean keeping track of whether this CV is intended to be used as write-only. Does not otherwise affect behaviour! Default is "false".

getWriteOnly

public boolean getWriteOnly()

Retrieve bean keeping track of whether this CV is intended to be used as write-only. Does not otherwise affect behaviour! Default is "false".

public boolean isToRead()

Overrides:

isToRead in class AbstractValue

setToWrite

public void setToWrite(boolean state)

Overrides:

setToWrite in class AbstractValue
