Call the [[Get]] method of this object with argument "length". + 2. Call ToUint32(Result(1)). + 3. Compute floor(Result(2)/2). + 4. Let k be 0. + 5. If k equals Result(3), return this object. + 6. Compute Result(2)k1. + 7. Call ToString(k). + 8. ToString(Result(6)). + 9. Call the [[Get]] method of this object with argument Result(7). + 10. Call the [[Get]] method of this object with argument Result(8). + 11. If this object has a property named by Result(8), go to step 12; but + if this object has no property named by Result(8), then go to either + step 12 or step 14, depending on the implementation. + 12. Call the [[Put]] method of this object with arguments Result(7) and + Result(10). + 13. Go to step 15. + 14. Call the [[Delete]] method on this object, providing Result(7) as the + name of the property to delete. + 15. If this object has a property named by Result(7), go to step 16; but if + this object has no property named by Result(7), then go to either step 16 + or step 18, depending on the implementation. + 16. Call the [[Put]] method of this object with arguments Result(8) and + Result(9). + 17. Go to step 19. + 18. Call the [[Delete]] method on this object, providing Result(8) as the + name of the property to delete. + 19. Increase k by 1. + 20. Go to step 5. + + Note that the reverse function is intentionally generic; it does not require + that its this value be an Array object. Therefore it can be transferred to other + kinds of objects for use as a method. Whether the reverse function can be applied + successfully to a host object is implementation dependent. + + Note: Array.prototype.reverse allows some flexibility in implementation + regarding array indices that have not been populated. This test covers the + cases in which unpopulated indices are not deleted, since the JavaScript + implementation does not delete uninitialzed indices. + + Author: christine@netscape.com + Date: 7 october 1997 +*/ + +var SECTION = "15.4.4.4-1"; +var VERSION = "ECMA_1"; +startTest(); + +writeHeaderToLog( SECTION + " Array.prototype.reverse()"); + +var ARR_PROTOTYPE = Array.prototype; + +new TestCase( SECTION, "Array.prototype.reverse.length", 0, Array.prototype.reverse.length ); + +// length of array is 0 +new TestCase( SECTION, + "var A = new Array(); A.reverse(); A.length", + 0, + eval("var A = new Array(); A.reverse(); A.length") ); + +test(); + +function CheckItems( R, A ) { + for ( var i = 0; i < R.length; i++ ) { + new TestCase( + SECTION, + "A["+i+ "]", + R[i], + A[i] ); + } +} +test(); + +function Object_1( value ) { + this.array = value.split(","); + this.length = this.array.length; + for ( var i = 0; i < this.length; i++ ) { + this[i] = eval(this.array[i]); + } + this.join = Array.prototype.reverse; + this.getClass = Object.prototype.toString; +} +function Reverse( array ) { + var r2 = array.length; + var k = 0; + var r3 = Math.floor( r2/2 ); + if ( r3 == k ) { + return array; + } + + for ( k = 0; k < r3; k++ ) { + var r6 = r2 - k - 1; +// var r7 = String( k ); + var r7 = k; + var r8 = String( r6 ); + + var r9 = array[r7]; + var r10 = array[r8]; + + array[r7] = r10; + array[r8] = r9; + } + + return array; +} +function Iterate( array ) { + for ( var i = 0; i < array.length; i++ ) { +// print( i+": "+ array[String(i)] ); + } +} + +function Object_1( value ) { + this.array = value.split(","); + this.length = this.array.length; + for ( var i = 0; i < this.length; i++ ) { + this[i] = this.array[i]; + } + this.reverse = Array.prototype.reverse; + this.getClass = Object.prototype.toString; +} |
