Method Detail

paintImage

protected abstract void paintImage(ResourceContext context,
                                   java.awt.Graphics2D g2d,
                                   java.awt.Color textColor,
                                   java.awt.Color borderColor)

paintBaseTriangle

protected void paintBaseTriangle(java.awt.Graphics2D g2d)

paint

protected void paint(ResourceContext context,
                     java.awt.Graphics2D g2d)

Description copied from class: Java2Dresource

Template method for create image as Applet-like paint.

Overrides:

paint in class Java2Dresource

Parameters:

context - - current resource context.

g2d - - graphics to paint.

getDimensions

public java.awt.Dimension getDimensions(javax.faces.context.FacesContext facesContext,
                                        java.lang.Object data)

Description copied from class: Java2Dresource

Primary calculation of image dimensions - used when HTML code is generated to render IMG's width and height Subclasses should override this method to provide correct sizes of rendered images

Overrides:

getDimensions in class Java2Dresource

Returns:

dimensions of the image to be displayed on page

getDimensions

protected java.awt.Dimension getDimensions(ResourceContext resourceContext)

Description copied from class: Java2Dresource

Secondary calculation is used basically by getImage method

Overrides:

getDimensions in class Java2Dresource

Returns:

getDataToStore

protected java.lang.Object getDataToStore(javax.faces.context.FacesContext context,
                                          java.lang.Object data)

Description copied from class: InternetResourceBase

Template method to construct resource-specific data ( to store in resource URI ). If resource must store any data in session or other cache, it must be done here. Since lightweight realisation, information for restore such data muct be returned by this method.

Overrides:

getDataToStore in class InternetResourceBase

Parameters:

data - - pass icon color and background color

context - - current faces context.

Returns:

- any Serializable object, or null.

getParameterValue

protected java.lang.String getParameterValue(javax.faces.context.FacesContext context,
                                             Skin skin,
                                             Skin defaultSkin,
                                             java.lang.String parameterName,
                                             java.lang.String defaultParameterName)

getDataToStore

protected java.lang.Object getDataToStore(javax.faces.context.FacesContext context,
                                          java.lang.String iconColorParam,
                                          java.lang.String defaultIconColorParam,
                                          java.lang.String borderColorParam,
                                          java.lang.String defaultBorderColorParam)

deserializeData

protected java.lang.Object deserializeData(byte[] objectArray)

Description copied from class: InternetResourceBase

Deserialize parameters object from byte array. By default, used Java de-serialisation from ObjectOutputStream , but implementations can override this method ( togewer with getDataToStore ) for implement short version.

Overrides:

deserializeData in class InternetResourceBase

Returns:

isCacheable

public boolean isCacheable()
