Otherwise this is simply a "*" operator. 113N/A // This returns the object size in HeapWords. 113N/A // Give size of objArrayOop in HeapWords minus the header 113N/A // Without UseCompressedOops, this is simply: 113N/A // oop->length() * HeapWordsPerOop; 113N/A // With narrowOops, HeapWordsPerOop is 1/2 or equal 0 as an integer. 113N/A // The oop elements are aligned up to wordSize 113N/A // special iterators for index ranges, returns size of object
