Creates a transient UIOutput using the Application, with the following characteristics:

componentType is javax.faces.HtmlOutputText.

transient is true.

escape is false.

id is FacesContext.getViewRoot().createUniqueId()

addVerbatimBeforeComponent

protected void addVerbatimBeforeComponent(UIComponentClassicTagBase parentTag,
                                          UIComponent verbatimComp,

setupResponseWriter

protected void setupResponseWriter()

Deprecated. the ResponseWriter is now set by ViewHandler.renderView(javax.faces.context.FacesContext, javax.faces.component.UIViewRoot)

encodeBegin

protected void encodeBegin()
                    throws IOException

Invoke encodeBegin on the associated UIComponent. Subclasses can override this method to perform custom processing before or after the UIComponent method invocation.

Throws:

IOException

encodeChildren

protected void encodeChildren()
                       throws IOException

Invoke encodeChildren on the associated UIComponent. Subclasses can override this method to perform custom processing before or after the UIComponent method invocation. This is only invoked for components whose getRendersChildren method returns true.

Throws:

IOException

encodeEnd

protected void encodeEnd()
                  throws IOException

Invoke encodeEnd on the associated UIComponent. Subclasses can override this method to perform custom processing before or after the UIComponent method invocation.

Throws:

IOException

findComponent

protected UIComponent findComponent(FacesContext context)
                             throws javax.servlet.jsp.JspException

Return the corresponding UIComponent for this tag, creating it if necessary.

If this is not the first time this method has been called, then return the cached _componentInstance instance found last time.

If this is not the first time this view has been seen, then locate the existing _componentInstance using the id attribute assigned to this tag and return it. Note that this is simple for components with user-assigned ids. For components with generated ids, the "reattachment" relies on the fact that UIViewRoot will generate the same id values for tags in this page as it did when first generating the view. For this reason all JSF tags within a JSTL "c:if" are required to have explicitly-assigned ids.

Otherwise create the _componentInstance, populate its properties from the xml attributes on this JSP tag and attach it to its parent.

When a _componentInstance is found or created the parent JSP tag is also told that the _componentInstance has been "seen". When the parent tag ends it will delete any components which were in the view previously but have not been seen this time; see doEndTag for more details.

Throws:

javax.servlet.jsp.JspException

hasBinding

protected abstract boolean hasBinding()

getPreviousOut

public javax.servlet.jsp.JspWriter getPreviousOut()
