Examples of PageContext

com.atlassian.confluence.renderer.PageContext
com.esri.gpt.framework.jsf.PageContext
Represents the context for an active JSF based page.
The PageContext is a JSF managed bean in request scope.
example.generics.persist.api.PageContext
javax.servlet.jsp.PageContext
A PageContext instance provides access to all the namespaces associated with a JSP page, provides access to several page attributes, as well as a layer above the implementation details. Implicit objects are added the pageContext automatically.
The PageContext class is an abstract class, designed to be extended to provide implementation dependent implementations thereof, by conformant JSP engine runtime environments. A PageContext instance is obtained by a JSP implementation class by calling the JspFactory.getPageContext() method, and is released by calling JspFactory.releasePageContext().
An example of how PageContext, JspFactory, and other classes can be used within a JSP Page Implementation object is given elsewhere.
The PageContext provides a number of facilities to the page/component author and page implementor, including:
- a single API to manage the various scoped namespaces
- a number of convenience API's to access various public objects
- a mechanism to obtain the JspWriter for output
- a mechanism to manage session usage by the page
- a mechanism to expose page directive attributes to the scripting environment
- mechanisms to forward or include the current request to other active components in the application
- a mechanism to handle errorpage exception processing
Methods Intended for Container Generated Code
Some methods are intended to be used by the code generated by the container, not by code written by JSP page authors, or JSP tag library authors.
The methods supporting lifecycle are initialize() and release()
The following methods enable the management of nested JspWriter streams to implement Tag Extensions: pushBody() and popBody()
Methods Intended for JSP authors
Some methods provide uniform access to the diverse objects representing scopes. The implementation must use the underlying Servlet machinery corresponding to that scope, so information can be passed back and forth between Servlets and JSP pages. The methods are: setAttribute(), getAttribute(), findAttribute(), removeAttribute(), getAttributesScope() and getAttributeNamesInScope() .
The following methods provide convenient access to implicit objects:
link.checker.persist.api.PageContext
org.apache.myfaces.view.facelets.PageContext
This class is used to encapsulate the information required at page scope. @author Leonardo Uribe @since 2.0.8
org.exoplatform.portal.mop.page.PageContext
@author Julien Viet
org.jfree.layouting.layouter.context.PageContext
The page context describes a logical page. The page holds the first and the last value of each counter and string. It also grants access to the global pseudo-page definitions. (Note: This is unclear and unclean and thus not yet implemented. Later it will be, of course...)
org.rendersnake.PageContext
PageContext provides the interface to page-render scoped variables. During rendering, each component can set or get values from a PageContext. Values set by a component are only visible to the component and all its child components. @author ernestmicklei
org.sonatype.nexus.httpclient.Page.PageContext
org.zkoss.cdi.weld.context.PageContext
Page context for {@link PageScoped}. @author henrichen
railo.runtime.PageContext
page context for every page object. the PageContext is a jsp page context expanded by CFML functionality. for example you have the method getSession to get jsp combatible session object (HTTPSession) and with sessionScope() you get CFML combatible session object (Struct,Scope).
