Et1 Test Harness: Final Values

Et1 Test Harness: Final Values

This is the Developer Version (runs from built code). Go to the Deployment Version (runs from built code).

Supported Platforms:

IE 5+ on Windows
Known Issue(s):
- Et1 does not provide finals in environments such as IE 5, 6, and 7, since they support neither const nor __defineSetter__ / __defineGetter__. This will probably change with IE 8. See Et1.oContext.Platform.supportsGetAndSet.
Mozilla-based browsers (Firefox 1.0+) on Windows o/s
Known Issue(s):
- None.
Mozilla-based browsers (Firefox 1.0+) on Non Windows o/s
Known Issue(s):
- None.
Safari 3.x
Known Issue(s):
- Only works with basic test. Fortunately, that is adequate for 90% of use-cases in development. The advanced test causes no error, but Safari 3.x does not finalize nested final values.
Safari (2.0.4) on Mac
Known Issue(s):
- Et1 does not provide finals in environments such as Safari 2.x, since they support neither const nor __defineSetter__ / __defineGetter__. See Et1.oContext.Platform.supportsGetAndSet.
Opera 9.5+ on all o/s (does not work < v 9.5; see Et1.oContext.Platform.supportsGetAndSet)
- None.

Verification Targets:

Generally, values made final should not be changeable at run-time.

Specific instructions: Click the 'test' button. If the test passes, go on to the More Advanced Test by copy-pasting the correct identifier name in the second input box and making the More Advanced Test the uncommented one in the textarea boxes. See the "Known Issues" section, below. Optionally alter the test input and test again.

Known Issues

Individual array elements cannot be made final, since they do not have named identifiers. The test will fail in those cases.

Input: Part A-1

Put the parent object name (identifier) or expression (i.e., {}, an empty object-literal) here:

Input: Part A-2

Put the property name (identifier) here:
(For the More Advanced Test, use H_TEST_HASH here).

Input: Part B

Put the final property definition(s) to evaluate here (can be a complex object, a string, etc.):

// Definition of a final value (basic test):
"apple"

/*- 
 *   More Advanced Test (use as an alternate):

// Definition of a final object:
{ 
    sA : "apple", 

    aA : [ "pear", 
           { sB : "blueberry", 
             oB : { 
               sC : "cherry",
               aD : [ 9, 2, { 
                              oC : { sE: "fig" } 
                            } 
                    ]
               } 
           } 
         ], 

    oA : { sD : "date" } 
};

*/

Input: Part B

Put code to try to change the values of the final properties here:

// A test to see if this value can actually be changed:

//     Basic Test:
Et1.oModel.oPage.oConfig.S_TEST = "orange";

//     Use this with the More Advanced Test:
// Et1.oModel.oPage.oConfig.H_TEST_HASH.sA = "orange";

Output: Name-Values
