Method Detail

lookup

public Object lookup(FacesContext facesContext,
                     String name)

Look up the given object using its JNDI name.

Parameters:

facesContext - the Faces context.

name - the JNDI name.

Returns:

the object, or null if an error occurs.

setField

public void setField(FacesContext facesContext,
                     Field field,
                     Object instance,
                     Object value)

Set the field.

Parameters:

facesContext - the Faces context.

field - the field.

instance - the instance.

value - the value.

invokeMethod

protected void invokeMethod(FacesContext facesContext,
                            Method method,
                            Object instance,
                            Object value)

Invoke the method.

Parameters:

facesContext - the Faces context.

method - the method.

instance - the instance.

value - the value.

apply

public void apply(FacesContext ctx,
                  Object... params)

Apply the Annotation(s). The act of doing so should affect the Faces runtime in some fashion (see the spec for the specific annotation types).

NOTE: when adding new types of components that can be annotated, the fact that we expose varargs here should be hidden. Type-safe methods should be added to AnnotationManager to clarify the contract.

Parameters:

ctx - the FacesContext for the current request

params - one or more arguments to the handler instance. The type and number may vary.
