FacesContext

java.lang.Object
- jakarta.faces.context.FacesContext

Direct Known Subclasses:

FacesContextWrapper
```
public abstract class FacesContext
extends java.lang.Object
```
FacesContext contains all of the per-request state information related to the processing of a single Jakarta Server Faces request, and the rendering of the corresponding response. It is passed to, and potentially modified by, each phase of the request processing lifecycle.

A FacesContext instance is associated with a particular request at the beginning of request processing, by a call to the getFacesContext() method of the FacesContextFactory instance associated with the current web application. The instance remains active until its release() method is called, after which no further references to this instance are allowed. While a FacesContext instance is active, it must not be referenced from any thread other than the one upon which the Jakarta Servlet container executing this web application utilizes for the processing of this request.

A FacesContext can be injected into a request scoped bean using @Inject FacesContext facesContext;

public FacesContext()
```
- Method Detail
  - getApplication
```
public abstract Application getApplication()
```
    Return the Application instance associated with this web application.
    
    It is valid to call this method during application startup or shutdown. If called during application startup or shutdown, returns the correct current Application instance.
    
    Returns:
    
    the Application instance associated with this web application.
    
    Throws:
    
    java.lang.IllegalStateException - if this method is called after this instance has been released
  - getAttributes
```
public java.util.Map<java.lang.Object,java.lang.Object> getAttributes()
```
    Return a mutable Map representing the attributes associated wth this FacesContext instance. This Map is useful to store attributes that you want to go out of scope when the Faces lifecycle for the current request ends, which is not always the same as the request ending, especially in the case of Jakarta Servlet filters that are invoked after the Faces lifecycle for this request completes. Accessing this Map does not cause any events to fire, as is the case with the other maps: for request, session, and application scope. When release() is invoked, the attributes must be cleared.
    
    The Map returned by this method is not associated with the request. If you would like to get or set request attributes, see ExternalContext.getRequestMap().
    The default implementation throws UnsupportedOperationException and is provided for the sole purpose of not breaking existing applications that extend this class.
    
    Returns:
    
    mutable Map representing the attributes associated wth this FacesContext instance.
    
    Throws:
    
    java.lang.IllegalStateException - if this method is called after this instance has been released
    
    Since:
    
    2.0
  - getPartialViewContext
```
public PartialViewContext getPartialViewContext()
```
    Return the PartialViewContext for this request. The PartialViewContext is used to control the processing of specified components during the execute portion of the request processing lifecycle (known as partial processing) and the rendering of specified components (known as partial rendering). This method must return a new PartialViewContext if one does not already exist.
    
    Returns:
    
    the instance of PartialViewContext for this request.

    Returns:

    Return the ELContext instance for this FacesContext instance. This ELContext instance has the same lifetime and scope as the FacesContext instance with which it is associated, and may be created lazily the first time this method is called for a given FacesContext instance. Upon creation of the ELContext instance, the implementation must take the following action:
    - Call the ELContext.putContext(java.lang.Class<?>, java.lang.Object) method on the instance, passing in FacesContext.class and the this reference for the FacesContext instance itself.
    - If the Collection returned by Application.getELContextListeners() is non-empty, create an instance of ELContextEvent and pass it to each ELContextListener instance in the Collection by calling the ELContextListener.contextCreated(jakarta.el.ELContextEvent) method.
    Returns:
    
    instance of ELContext.

Faces implementations may choose to pool instances in the associated FacesContextFactory to avoid repeated object creation and garbage collection. After release() is called on a FacesContext instance (until the FacesContext instance has been recycled by the implementation for re-use), calling any other methods will cause an IllegalStateException to be thrown.
    
    If a call was made to getAttributes() during the processing for this request, the implementation must call clear() on the Map returned from getAttributes(), and then de-allocate the data-structure behind that Map.
