    Description copied from interface: JavaSource
    
    Expected to return a java source representation of itself such that it could be turned into a literal java expression to be compiled and executed for ExpressionAccessor.get(OgnlContext, Object) calls.
    
    Specified by:
    
    toGetSourceString in interface JavaSource
    
    Overrides:
    
    toGetSourceString in class BooleanExpression
    
    Parameters:
    
    context - the OgnlContext within which to perform the operation.
    
    target - the Object from which to retrieve the get source string.
    
    Returns:
    
    Literal java string representation of an object get.
