Class DoubleTagSupport

java.lang.Object
  extended by javax.servlet.jsp.tagext.TagSupport
      extended by com.bea.web.tag.AbstractInputTagSupport
          extended by com.bea.web.tag.DoubleTagSupport
All Implemented Interfaces:
Serializable, javax.servlet.jsp.tagext.IterationTag, javax.servlet.jsp.tagext.JspTag, javax.servlet.jsp.tagext.Tag

public class DoubleTagSupport
extends AbstractInputTagSupport
implements 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.

Specified by:
doStartTag in interface javax.servlet.jsp.tagext.Tag
Overrides:
doStartTag in class javax.servlet.jsp.tagext.TagSupport
Returns:
javax.servlet.jsp.tagext.Tag.SKIP_BODY to indicate to the tag handler to skip body evaluation.

release

public void release()
Resets the internal state of this instance. This is called after this tag has rendered itself in the doStartTag method. This is needed because the tag handler will reuse this instance for every int tag on the page.

Specified by:
release in interface javax.servlet.jsp.tagext.Tag
Overrides:
release in class AbstractInputTagSupport
