public class DoubleTagSupport

extends AbstractInputTagSupport

implements java.io.Serializable

Provides the rendering logic for an HTML form field that accepts float values only. In addition, each instance of this class uses an instance of com.bea.web.validation.DoubleWord to perform runtime validation of the value for this field. This class places an DoubleWord instance in application scope, i.e. accessible via the ServletContext object. The ServletContext is shared by all servlets in a Web application. Consequently, the controller servlet can access the DoubleWord to validate user input passed in the HTTP request for this form field.

doStartTag

public int doStartTag()

Prints the tag to the JSP writer.

Returns:

javax.servlet.jsp.tagext.Tag.SKIP_BODY to indicate to the tag handler to skip body evaluation.

Overrides:

doStartTag in class javax.servlet.jsp.tagext.TagSupport

release
