OneColorBasedResource

public OneColorBasedResource(int width,
                             int height,
                             java.lang.String basicColorParamName)

Method Detail

getDimensions

protected java.awt.Dimension getDimensions(org.ajax4jsf.resource.ResourceContext resourceContext)

Description copied from class: Java2Dresource

Secondary calculation is used basically by getImage method

Overrides:

getDimensions in class Java2Dresource

Returns:

See Also:

Java2Dresource.getDimensions(ResourceContext)

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

See Also:

Java2Dresource.getDimensions(FacesContext, Object)

isCacheable

public boolean isCacheable(org.ajax4jsf.resource.ResourceContext ctx)

Specified by:

isCacheable in interface org.ajax4jsf.resource.InternetResource

Overrides:

isCacheable in class InternetResourceBase

See Also:

InternetResourceBase.isCacheable(ResourceContext)

getBasicColor

public java.awt.Color getBasicColor()

Gets value of basicColor field.

Returns:

value of basicColor field

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:

context - - current faces context.

data - - data for build information, usually current UIComponent

Returns:

- any Serializable object, or null.

See Also:

InternetResourceBase.getDataToStore(FacesContext, Object)

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:

See Also:

InternetResourceBase.deserializeData(byte[])
