Class AttributeTag
java.lang.Object
javax.servlet.jsp.tagext.TagSupport
javax.faces.webapp.AttributeTag
- All Implemented Interfaces:
- Serializable, javax.servlet.jsp.tagext.IterationTag, javax.servlet.jsp.tagext.Tag
public class AttributeTag
- extends javax.servlet.jsp.tagext.TagSupport
This tag associates an attribute with the nearest parent
UIComponent.
When the value is not an EL expression, this tag has the same effect
as calling component.getAttributes.put(name, value). When the attribute
name specified matches a standard property of the component, that
property is set. However it is also valid to assign attributes
to components using any arbitrary name; the component itself won't
make any use of these but other objects such as custom renderers,
validators or action listeners can later retrieve the attribute
from the component by name.
When the value is an EL expression, this tag has the same effect
as calling component.setValueBinding. A call to method
component.getAttributes().get(name) will then cause that
expression to be evaluated and the result of the expression is
returned, not the original EL expression string.
See the javadoc for UIComponent.getAttributes for more details.
Unless otherwise specified, all attributes accept static values
or EL expressions.
