clone (BlurFilter.clone method)
public clone() : BlurFilter
Returns a copy of this filter object.
Availability: ActionScript 1.0; Flash Player 8
Returns
BlurFilter - A new BlurFilter instance with all the same properties as the original BlurFilter
instance.
Example
The following example creates three BlurFilter objects and compares them. You can create the
filter_1 object by using the BlurFilter constructor. You can create the filter_2 object
by setting it equal to filter_1. You can create the clonedFilter object by cloning
filter_1. Notice that although filter_2 evaluates as being equal to filter_1,
clonedFilter does not, even though it contains the same values as filter_1.
import flash.filters.BlurFilter;
var filter_1:BlurFilter = new BlurFilter(30, 30, 2);
var filter_2:BlurFilter = filter_1;
var clonedFilter:BlurFilter = filter_1.clone();
trace(filter_1 == filter_2); // true
trace(filter_1 == clonedFilter); // false
for(var i in filter_1) {
trace(">> " + i + ": " + filter_1[i]);
// >> clone: [type Function]
// >> quality: 2
// >> blurY: 30
// >> blurX: 30
}
for(var i in clonedFilter) {
trace(">> " + i + ": " + clonedFilter[i]);
// >> clone: [type Function]
// >> quality: 2
// >> blurY: 30
// >> blurX: 30
}
To further demonstrate the relationships between filter_1, filter_2, and clonedFilter,
the following example modifies the quality property of filter_1. Modifying quality
demonstrates that the clone() method creates a new instance based on values of the
filter_1 instead of referring to the values.
