Direct Known Subclasses:

ImageAction

public class CellContentsImageRenderer
implements TableCellContentsRenderer

The CellContentsImageRenderer is a TransformationBean™ that generates the appropriate HTML 4.0 to represent the contents of a cell as an HTML image.

Note that the toString() method on this class calls the write method, which may have undesirable side effects. See BaseTransformation.toString() for more information. Debuggers often use toString() to show the value of a variable, and this may cause unexpected behavior while debugging

For More Information:

JSP custom tags provide an alternative to using the TransformationBeans™. Visit the Custom Tag Library Reference for additional information on the sas:CellContentsImageRenderer custom tag.
