fetches this string from the intern hashtable . if two strings are considered equal , by the equals method , then intern will return the same string instance . ie . if s1.equals s2 then s1.intern == s2.intern . all string literals and string-valued constant expressions are already interned . concode_field_sep WeakHashMap internTable concode_field_sep placeholderType placeHolder
