System.arraycopy() vs System.arraymove()

I assume that there is a function arraycopy() in the class java.lang.System. This is a native and efficient function. I do think that behind this navitve function there is a C memcpy() function call.

So with the same idea why there is no System.arraymove() inside the J2SE 5.0 ? And behind this native function we should place a C memmove() function call.

I hope (if it is usefull and relevant) this will be available in JDK 1.5.1....

Best regards.

System.arraycopy() is already done as a memmove(), not as a memcpy():

If the src and dest arguments refer to the same array object, then the copying is

performed as if the components at positions srcPos through srcPos+length-1

were first copied to a temporary array with length components and then the

contents of the temporary array were copied into positions destPos through

destPos+length-1 of the destination array.

So there's no need for an arraymove().
