bodyContent

UIComponentBodyTag
public UIComponentBodyTag()
doAfterBody
public int doAfterBody()
throws javax.servlet.jsp.JspException
- Description copied from interface:
javax.servlet.jsp.tagext.IterationTag
- Process body (re)evaluation. This method is invoked by the
JSP Page implementation object after every evaluation of
the body into the BodyEvaluation object. The method is
not invoked if there is no body evaluation.
If doAfterBody returns EVAL_BODY_AGAIN, a new evaluation of the
body will happen (followed by another invocation of doAfterBody).
If doAfterBody returns SKIP_BODY, no more body evaluations will occur,
and the doEndTag method will be invoked.
If this tag handler implements BodyTag and doAfterBody returns
SKIP_BODY, the value of out will be restored using the popBody
method in pageContext prior to invoking doEndTag.
The method re-invocations may be lead to different actions because
there might have been some changes to shared state, or because
of external computation.
The JSP container will resynchronize the values of any AT_BEGIN and
NESTED variables (defined by the associated TagExtraInfo or TLD) after
the invocation of doAfterBody().
- Specified by:
doAfterBody in interface javax.servlet.jsp.tagext.IterationTag
doInitBody
public void doInitBody()
throws javax.servlet.jsp.JspException
- Description copied from interface:
javax.servlet.jsp.tagext.BodyTag
- Prepare for evaluation of the body.
This method is invoked by the JSP page implementation object
after setBodyContent and before the first time
the body is to be evaluated.
This method will not be invoked for empty tags or for non-empty
tags whose doStartTag() method returns SKIP_BODY or EVAL_BODY_INCLUDE.
The JSP container will resynchronize the values of any AT_BEGIN and
NESTED variables (defined by the associated TagExtraInfo or TLD) after
the invocation of doInitBody().
- Specified by:
doInitBody in interface javax.servlet.jsp.tagext.BodyTag
release
public void release()
- Description copied from interface:
javax.servlet.jsp.tagext.Tag
- Called on a Tag handler to release state.
The page compiler guarantees that JSP page implementation
objects will invoke this method on all tag handlers,
but there may be multiple invocations on doStartTag and doEndTag in between.
- Specified by:
release in interface javax.servlet.jsp.tagext.Tag- Overrides:
release in class UIComponentTag
getBodyContent
public javax.servlet.jsp.tagext.BodyContent getBodyContent()
setBodyContent
public void setBodyContent(javax.servlet.jsp.tagext.BodyContent bodyContent)
- Description copied from interface:
javax.servlet.jsp.tagext.BodyTag
- Set the bodyContent property.
This method is invoked by the JSP page implementation object at
most once per action invocation.
This method will be invoked before doInitBody.
This method will not be invoked for empty tags or for non-empty
tags whose doStartTag() method returns SKIP_BODY or EVAL_BODY_INCLUDE.
When setBodyContent is invoked, the value of the implicit object out
has already been changed in the pageContext object. The BodyContent
object passed will have not data on it but may have been reused
(and cleared) from some previous invocation.
The BodyContent object is available and with the appropriate content
until after the invocation of the doEndTag method, at which case it
may be reused.
- Specified by:
setBodyContent in interface javax.servlet.jsp.tagext.BodyTag
getPreviousOut
public javax.servlet.jsp.JspWriter getPreviousOut()
getDoStartValue
protected int getDoStartValue()
throws javax.servlet.jsp.JspException
- Overrides:
getDoStartValue in class UIComponentTag
getDoAfterBodyValue
protected int getDoAfterBodyValue()
throws javax.servlet.jsp.JspException
