- public class MemSet
- extends Function
<typeX> MemSet(MEM_typeX memory, INT index, <typeX> value)
MemSet is a generic Function which takes three arguments. The first is an
indexed memory. The second is an index into that memory. The third is the
value that the specified location of the specified memory needs to be set.
MemGet needs to be instantiated to work with a particular type of memory.
Valid memory types include MEM_OBJECT, MEM_BYTE, MEM_SHORT, MEM_INT,
MEM_LONG, MEM_FLOAT, MEM_DOUBLE, MEM_CHAR, and MEM_BOOLEAN.
