Package org.jboss.seam.solder.el Description

Provides an application wide EL value and method expression resolution facility as well as a improved API for evaluating EL expressions aimed at ease of use.

To use the improved API, inject the Expressions bean, and call one of it's evaluate methods:

    @Inject Expressions expressions;
    
    ...
    
    Address address = expressions.evaluateValueExpression("#{person.address}");
    
    ...
    
    expressions.evaluateMethodExpression("#{userManager.savePerson}");
 

By default Seam Solder will only resolve beans from CDI, and provides no function or variable mapping.

If you integrating Seam Solder into an environment that provides a source of beans for EL resolution, you can register an ELResolver by creating a bean of type ELResolver with the qualifier @Resolver.

If you integrating Seam Solder into an environment that provides a function or variable mapper, you can also provide an alternative FunctionMapper or VariableMapper. Simply create a bean exposing your alternative implementation with the qualifier @Mapper.
