Class IntegerTagSupport
java.lang.Object
javax.servlet.jsp.tagext.TagSupport
com.bea.web.tag.AbstractInputTagSupport
com.bea.web.tag.IntegerTagSupport
- All Implemented Interfaces:
- Serializable, javax.servlet.jsp.tagext.IterationTag, javax.servlet.jsp.tagext.JspTag, javax.servlet.jsp.tagext.Tag
public class IntegerTagSupport
- extends AbstractInputTagSupport
- implements Serializable
Provides the rendering logic for an HTML form field that accepts integer
values only. In addition, each instance of this class uses an instance of
com.bea.web.validation.IntegerWord
to perform runtime
validation of the value for this field. This class places an IntegerWord
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 IntegerWord 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.
