public class MethodExpressionParser

implements Serializable

Parses an action expression. This expression is assumed to be of the form #{value-expression.method-name(param-list)} The (param-list) is optional. The (param-list) can be empty. ${ } notation may be used instead of #{ } Square bracket notation: i.e. value-expression[method-name] is also allowed. String literals surrounded by single or double quotes can be passed as params. example: #{register.register(user, 'login page')} Also, the entire expression can be a simple String. In this case, there is no bracket notation at all. i.e. foo
