of

Returns @GraphicImageBean URL based on given expression string, image type and last modified. The expression string must be a quoted string. Any nested quotes can be escaped with backslash. The image type is represented as file extension. E.g. "jpg", "png", "gif", "ico", "svg", "bmp", "tiff", etc. The "last modified" timestamp can be either a java.lang.Long, java.util.Date, or java.lang.String which is parseable as java.lang.Long.

Usage example:

<a href="#{of:graphicImageURLWithTypeAndLastModified('images.full(product.imageId)', 'png', product.lastModified)}">
    <o:graphicImage value="#{images.thumb(product.imageId)}" type="png" lastModified="#{product.lastModified}" />
</a>
