Method Detail

getValue
public Object getValue(jakarta.el.ELContext context, Object base, Object property)
If
base
is a composite component andproperty
isattrs
, return a newExpressionEvalMap
which wraps the composite component's attributes map.The
ExpressionEvalMap
simple evaluates anyValueExpression
instances stored in the composite component's attribute map and returns the result.If
base
is a composite component andproperty
isparent
attempt to resolve the composite componet parent of the current composite component by callingUIComponent.getCompositeComponentParent(jakarta.faces.component.UIComponent)
) and returning that value.- Specified by:

getType
public Class<?> getType(jakarta.el.ELContext context, Object base, Object property)

setValue
public void setValue(jakarta.el.ELContext context, Object base, Object property, Object value)

isReadOnly
public boolean isReadOnly(jakarta.el.ELContext context, Object base, Object property)
Readonly, so return
true

getFeatureDescriptors
public Iterator<FeatureDescriptor> getFeatureDescriptors(jakarta.el.ELContext context, Object base)
This
ELResolver
currently returns no feature descriptors as we have no way to effectively iterate over the UIComponent attributes Map.- Overrides:

getCommonPropertyType
public Class<?> getCommonPropertyType(jakarta.el.ELContext context, Object base)
attrs
is considered aString
property.- Specified by:

getEvalMapFor
public Map<String,Object> getEvalMapFor(UIComponent c, FacesContext ctx)
Creates (if necessary) and caches an
ExpressionEvalMap
instance associated with the owningUIComponent
- Parameters:
c
- the owningUIComponent
ctx
- theFacesContext
for the current request- Returns:
- an
ExpressionEvalMap
for the specified component
