Copy a string: Difference between revisions

Instead, maybe you want to create a <code>StringBuffer</code> (mutable string) from an existing String or StringBuffer:

StringBuffer srcCopy = new StringBuffer("Hello");

In Standard ML, <code>string</code>s are immutable, so you don't copy it.

Instead, maybe you want to create a <code>CharArray.array</code> (mutable string) from an existing <code>string</code>:

val src = "Hello";

val srcCopy = CharArray.array (size src, #"x"); (* 'x' is just dummy character *)

CharArray.copyVec {src = src, dst = srcCopy, di = 0};

src = CharArray.vector srcCopy; (* evaluates to true *)

or from another <code>CharArray.array</code>:

val srcCopy2 = CharArray.array (CharArray.length srcCopy, #"x"); (* 'x' is just dummy character *)

CharArray.copy {src = srcCopy, dst = srcCopy2, di = 0};
