    Description copied from class: VariableResolver
    
    Returns the value of the variable. This class will not try to further expand variables in the returned value. If the implementation wants to do so, that is the implementation's responsibility.
    
    Specified by:
    
    getVariableValue in class VariableResolver
    
    Returns:
    
    null if the variable is not found. The caller will report an error. When the variable is not found, it's also legal to throw TranslationException, which is an useful technique if the implementation would like to report additional errors.
    
    Throws:
    
    TranslationException
  - needsResolving

public static boolean needsResolving(String value)
