Examples of org.apache.myfaces.test.el.MockValueExpression

org.apache.myfaces.test.el.MockValueExpression
Mock implementation of ValueExpression.

This implementation supports a limited subset of overall expression functionality:
- A literal string that contains no expression delimiters.
- An expression that starts with "#{" or "${", and ends with "}".
@since 1.0.0
