      extended by com.bea.web.tag.AbstractInputTagSupport

All Implemented Interfaces:
Serializable, javax.servlet.jsp.tagext.IterationTag, javax.servlet.jsp.tagext.JspTag, javax.servlet.jsp.tagext.Tag

public class DateTagSupport
extends AbstractInputTagSupport
implements Serializable

Provides the rendering logic for an HTML form field that accepts date values only. In addition, each instance of this class uses an instance of com.bea.web.validation.DateWord to perform runtime validation of the value for this field. This class places an DateWord 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 DateWord to validate user input passed in the HTTP request for this form field.

Constructor Detail

DateTagSupport

public DateTagSupport()
Default constructor, all subclasses of javax.servlet.jsp.tagext.TagSupport are required to only define a public constructor with the same signature, and to call the superclass constructor.

Method Detail

setLenient

public final void setLenient(boolean bIsLenient)

setFormat

public final void setFormat(String strFormat)

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
