| Format: copy ( object ) |
| Format: clone ( object ) |
Purpose: Performs a deep copy of an object. That means a new object is created and all fields are copied into it. If a field itself contains an object this one is recursively copied.
Return Values: Returns an object which is the copy of the object.
| Caution! This function doesn't detect and resolve cycles. Thus, the object passed to this function must have a tree-like structure. |
Example:
| resulting output: | |
<let x=splitstring("A,B,C");
>x=<? x;
y=x;
z=copy(x);
x[0]="D";x[1]="E";y[2]="F";
>x=<? x;
>y=<? y;
>z=<? z;
> | x=([0]="A", [1]="B", [2]="C")x=([0]="D", [1]="E", [2]="F")y=([0]="D", [1]="E", [2]="F")z=([0]="A", [1]="B", [2]="C") |
