CalculatedProperty

public CalculatedProperty()

CalculatedProperty

public CalculatedProperty(String type,
GamePiece inner)

Method Details

boundingBox

public Rectangle boundingBox()

Description copied from interface: GamePiece

The area which this GamePiece occupies when drawn at the point (0,0)

Specified by:

boundingBox in interface GamePiece

draw

public void draw(Graphics g,
int x,
int y,
Component obs,
double zoom)

Description copied from interface: GamePiece

Draw this GamePiece

Specified by:

draw in interface GamePiece

x - x-location of the center of the piece

y - y-location of the center of the piece

obs - the Component on which this piece is being drawn

zoom - the scaling factor.

getName

public String getName()

Description copied from interface: GamePiece

The plain English name for this piece

Specified by:

getName in interface GamePiece

myGetKeyCommands

protected KeyCommand[] myGetKeyCommands()

Specified by:

myGetKeyCommands in class Decorator

Returns:

See Also:

Decorator.getState()

myGetType

public String myGetType()

Specified by:

public Command myKeyEvent(KeyStroke stroke)

Description copied from class: Decorator

The response of this trait alone to the given KeyStroke

Specified by:

myKeyEvent in class Decorator

Parameters:

stroke - Stroke to apply

Returns:

mySetState

public void mySetState(String newState)

Description copied from class: Decorator

Set just the state of this trait

Specified by:

mySetState in class Decorator

See Also:

Decorator.myGetState()

getShape

public Shape getShape()

Description copied from interface: GamePiece

The shape of the piece from the user's viewpoint. This defines the area in which the user must click to select or move the piece, for example. Like GamePiece.boundingBox(), it assumes the position is (0,0) and must be translated to the actual location where the piece is being drawn.

Specified by:

getShape in interface GamePiece

getDescription

public String getDescription()

Description copied from interface: EditablePiece

A plain-English description of this type of piece

Specified by:

getDescription in interface EditablePiece

public void mySetType(String type)

Description copied from interface: EditablePiece

Set the type information for this piece. See Decorator.myGetType()

Specified by:

mySetType in interface EditablePiece

getExpression

protected String getExpression()

getProperty

public Object getProperty(Object key)

Return the value of this trait's property. Evaluating Expressions can lead to infinite loops and eventually a Stack Overflow. Trap and report this

Specified by:

getProperty in interface GamePiece

Specified by:

getProperty in interface PropertySource

Overrides:

getProperty in class Decorator

getLocalizedProperty

public Object getLocalizedProperty(Object key)

Specified by:

getLocalizedProperty in interface PropertySource

Overrides:

getLocalizedProperty in class Decorator

evaluate

protected String evaluate()

Evaluate the calculated property. Do not call Decorator.reportDataError as this will probably cause an infinite reporting loop.

Returns:

value

getEditor

public PieceEditor getEditor()

Description copied from interface: EditablePiece

Get the configurer for this trait

Specified by:

getEditor in interface EditablePiece

Overrides:

getEditor in class Decorator

getComponentName

Specified by:

getComponentName in interface RecursionLimiter.Loopable

getComponentTypeName

public String getComponentTypeName()

Specified by:

getComponentTypeName in interface RecursionLimiter.Loopable

getPropertyNames

public List<String> getPropertyNames()

Return Property names exposed by this trait

Specified by:

getPropertyNames in interface PropertyNameSource

Overrides:

getPropertyNames in class Decorator
