Evaluate AdditiveExpression. + 2. Call GetValue(Result(1)). + 3. Evaluate MultiplicativeExpression. + 4. Call GetValue(Result(3)). + 5. Call ToPrimitive(Result(2)). + 6. Call ToPrimitive(Result(4)). + 7. If Type(Result(5)) is String or Type(Result(6)) is String, go to step 12. + (Note that this step differs from step 3 in the algorithm for comparison + for the relational operators in using or instead of and.) + 8. Call ToNumber(Result(5)). + 9. Call ToNumber(Result(6)). + 10. Apply the addition operation to Result(8) and Result(9). See the discussion below (11.6.3). + 11. Return Result(10). + 12. Call ToString(Result(5)). + 13. Call ToString(Result(6)). + 14. Concatenate Result(12) followed by Result(13). + 15. Return Result(14). + + Note that no hint is provided in the calls to ToPrimitive in steps 5 and 6. + All native ECMAScript objects except Date objects handle the absence of a + hint as if the hint Number were given; Date objects handle the absence of a + hint as if the hint String were given. Host objects may handle the absence + of a hint in some other manner. + + This test does not cover cases where the Additive or Mulplicative expression + ToPrimitive is string. + + Author: christine@netscape.com + Date: 12 november 1997 +*/ +var SECTION = "11.6.1-1"; +var VERSION = "ECMA_1"; +startTest(); + +writeHeaderToLog( SECTION + " The Addition operator ( + )"); + +// tests for "MyValuelessObject", where the value is +// set in the object's prototype, not the object itself. + +new TestCase( SECTION, + "var EXP_1 = new MyValuelessObject(true); var EXP_2 = new MyValuelessObject(false); EXP_1 + EXP_2", + 1, + eval("var EXP_1 = new MyValuelessObject(true); var EXP_2 = new MyValuelessObject(false); EXP_1 + EXP_2") ); + +new TestCase( SECTION, + "var EXP_1 = new MyValuelessObject(new Boolean(true)); var EXP_2 = new MyValuelessObject(new Boolean(false)); EXP_1 + EXP_2", + "truefalse", + eval("var EXP_1 = new MyValuelessObject(new Boolean(true)); var EXP_2 = new MyValuelessObject(new Boolean(false)); EXP_1 + EXP_2") ); + +// tests for "MyValuelessObject", where the value is +// set in the object's prototype, not the object itself. + + +new TestCase( SECTION, + "var EXP_1 = new MyValuelessObject(100); var EXP_2 = new MyValuelessObject(-1); EXP_1 + EXP_2", + 99, + eval("var EXP_1 = new MyValuelessObject(100); var EXP_2 = new MyValuelessObject(-1); EXP_1 + EXP_2") ); + +new TestCase( SECTION, + "var EXP_1 = new MyValuelessObject(new Number(100)); var EXP_2 = new MyValuelessObject(new Number(-1)); EXP_1 + EXP_2", + "100-1", + eval("var EXP_1 = new MyValuelessObject(new Number(100)); var EXP_2 = new MyValuelessObject(new Number(-1)); EXP_1 + EXP_2") ); + +new TestCase( SECTION, + "var EXP_1 = new MyValuelessObject( new MyValuelessObject( new Boolean(true) ) ); EXP_1 + EXP_1", + "truetrue", + eval("var EXP_1 = new MyValuelessObject( new MyValuelessObject( new Boolean(true) ) ); EXP_1 + EXP_1") ); + +test(); + +function MyProtoValuelessObject() { + this.valueOf = new Function ( "" ); + this.__proto__ = null; +} + +function MyProtolessObject( value ) { + this.valueOf = new Function( "return this.value" ); + this.__proto__ = null; + this.value = value; +} + +function MyValuelessObject(value) { + this.__proto__ = new MyPrototypeObject(value); +} +function MyPrototypeObject(value) { + this.valueOf = new Function( "return this.value;" ); + this.toString = new Function( "return (this.value + '');" ); + this.value = value; +} + +function MyObject( value ) { + this.valueOf = new Function( "return this.value" ); + this.value = value; +} |
