Method Details

usesCVs

public CvValue[] usesCVs()

Description copied from class: VariableValue

Provide access to CVs used by this Variable.

Specified by:

usesCVs in class VariableValue

Returns:

an array of CVs used by this Variable

getCvDescription

public String getCvDescription()

Provide a user-readable description of the CVs accessed by this variable.

Overrides:

getCvDescription in class VariableValue

Returns:

a user-readable description

setToolTipText

public void setToolTipText(String t)

Description copied from class: VariableValue

Set tooltip text to be used by both the "value" and representations of this Variable.

This is expected to be overridden in subclasses to change their internal info.

Overrides:

setToolTipText in class VariableValue

Parameters:

t - the tooltip text to be used

See Also:

• VariableValue.updateRepresentation(javax.swing.JComponent)

rangeVal

public Object rangeVal()

Description copied from class: VariableValue

Gets a (usually text) description of the variable type and range.

Specified by:

rangeVal in class VariableValue

Returns:

description of the variable type and range

enterField

void enterField()

exitField

void exitField()

updatedTextField

void updatedTextField()

Description copied from class: VariableValue

This should be overridden by any implementation.

Overrides:

updatedTextField in class VariableValue

actionPerformed

public void actionPerformed(ActionEvent e)

ActionListener implementations

Specified by:

actionPerformed in interface ActionListener

focusGained

public void focusGained(FocusEvent e)

FocusListener implementations

Specified by:

focusGained in interface FocusListener

focusLost

public void focusLost(FocusEvent e)

Specified by:

focusLost in interface FocusListener

getValueString

public String getValueString()

Specified by:

getValueString in class VariableValue

Returns:

String that can (usually) be interpreted as an integer

setIntValue

public void setIntValue(int i)

Description copied from class: VariableValue

Set the value from a single number.

In some cases, e.g. speed tables, this will result in complex behavior, where setIntValue(getIntValue()) results in something unexpected.

Specified by:

setIntValue in class VariableValue

Parameters:

i - the integer value to set

getIntValue

public int getIntValue()

Description copied from class: VariableValue

Get the value as a single integer.

In some cases, e.g. speed tables, this will result in complex behavior, where setIntValue(getIntValue()) results in something unexpected.

Specified by:

getIntValue in class VariableValue

Returns:

the value as an integer

getValueObject

public Object getValueObject()

Specified by:

getValueObject in class VariableValue

Returns:

Value as a native-form Object

getCommonRep

public Component getCommonRep()

Description copied from class: VariableValue

Get a display representation Object of this variable.

The actual stored value of a variable is not the most interesting thing. Instead, you usually get an Object representation for display in a table, etc. Modification of the state of that object then gets reflected back, causing the underlying CV objects to change.

Specified by:

getCommonRep in class VariableValue

Returns:

the Object representation for display purposes

setValue

public void setValue(int value)

setColor

void setColor(Color c)

Description copied from class: AbstractValue

Method to handle color changes for states.

Specified by:

setColor in class AbstractValue

Parameters:

c - the desired colour

getNewRep

public Component getNewRep(String format)

Description copied from class: VariableValue

Creates a new Object representation for display purposes, using the specified format.

Specified by:

getNewRep in class VariableValue

Parameters:

format - a name representing

Returns:

an Object representation for display purposes

setCvState

public void setCvState(AbstractValue.ValueState state)

Notify the connected CVs of a state change from above

Specified by:

setCvState in class VariableValue

Parameters:

state - the new state to set

isChanged

public boolean isChanged()

Description copied from class: VariableValue

Determine whether this Variable is "changed", so that "read changes" and "write changes" will act on it.

Specified by:

isChanged in class VariableValue

Returns:

true if Variable is "changed"

See Also:

• VariableValue.considerChanged(jmri.jmrit.symbolicprog.CvValue)

setToRead

public void setToRead(boolean state)

Description copied from class: VariableValue

Mark whether this object needs to be read.

Simple implementation for the case of a single CV. Intended to be sufficient for many subclasses.

Overrides:

setToRead in class VariableValue

Parameters:

state - true if the object needs to be read, false otherwise

See Also:

• AbstractValue

setToWrite

public void setToWrite(boolean state)

Description copied from class: VariableValue

Mark whether this object needs to be written.

Simple implementation for the case of a single CV. Intended to be sufficient for many subclasses.

Overrides:

setToWrite in class VariableValue

Parameters:

state - true if the object needs to be written, false otherwise

See Also:

• AbstractValue
