Class MetaMethodExpression

java.lang.Object

javax.el.Expression

javax.el.MethodExpression

org.nuxeo.ecm.platform.ui.web.binding.MetaMethodExpression

All Implemented Interfaces:

Serializable

public class MetaMethodExpression
extends MethodExpression
implements Serializable

Meta method expression used to invoke the EL expression that is already the result of a method expression.

For instance it is useful to use this expression to provide action links defined in NXActions extensions with links like #{documentAction.createDocument('Domain')}.

There is no more than one level of abstraction:

• the expression method value can be a standard method expression (with parameters or not);
• the expression method value can result in another expression method value after being invoke, in which case it is reinvoked again using the same context;
• no further method invoking will be performed.
