Class ImageDataContentHandler

java.lang.Object
  java.awt.Component
      org.jboss.soa.esb.actions.soap.attachment.ImageDataContentHandler

All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.activation.DataContentHandler

public class ImageDataContentHandler
extends java.awt.Component
implements javax.activation.DataContentHandler

ImageDataContentHandler is a JAF content handler that handles marshalling/unmarshalling between Image objects and a stream. This handler provides support for all mime types handled by the ImageIO implementation on the virtual machine that this class is ran under. These are dynamically registered, so any custom ImageIO plugins are discovered and used. It's important to note that some mime types (for example image/gif) may not have encoding support provided by the ImageIO implementation. If this happens an exception will be thrown indicating the lack of encoding support.

Constructor Detail

ImageDataContentHandler

public ImageDataContentHandler()

Method Detail

getContent

public java.lang.Object getContent(javax.activation.DataSource ds)
                            throws java.io.IOException

Returns a Image from the specified data source.

Specified by:

getContent in interface javax.activation.DataContentHandler

Parameters:

ds - the activation datasource

Returns:

an AWT image object

Throws:

java.io.IOException

getTransferData

public java.lang.Object getTransferData(java.awt.datatransfer.DataFlavor df,
                                        javax.activation.DataSource ds)
                                 throws java.awt.datatransfer.UnsupportedFlavorException,
                                        java.io.IOException

Returns a Imagefrom the specified data source. This method is useless for this content handler because the image format is dynamically discovered.

Specified by:

getTransferData in interface javax.activation.DataContentHandler

Parameters:

df - the flavor specifiying the mime type of ds

ds - the activation data source

Returns:

an AWT image object

Throws:

java.awt.datatransfer.UnsupportedFlavorException

java.io.IOException

getTransferDataFlavors

public java.awt.datatransfer.DataFlavor[] getTransferDataFlavors()

Returns the acceptable data flavors that this content handler supports.

Specified by:

getTransferDataFlavors in interface javax.activation.DataContentHandler

Returns:

array of ActivationDataHandlers

writeTo

public void writeTo(java.lang.Object obj,
                    java.lang.String mimeType,
                    java.io.OutputStream os)
             throws java.io.IOException

Writes the passed in Image object using the specified mime type to the specified output stream.

Specified by:

writeTo in interface javax.activation.DataContentHandler

Parameters:

obj - an AWT image object

mimeType - the mime type of the image format to use

os - the output stream to write this image to

Throws:

java.io.IOException
