Marker interface for telling that the underlying char array is directly accessible This interface is missing from the JVM although String, StringBuffer and StringBuilder all have this method.

|  | void | getChars(int srcBegin, int srcEnd, char[] dst, int dstBegin)Characters are copied from this sequence into the destination character array dst. | 
 Characters are copied from this sequence into the
 destination character array dst. The first character to
 be copied is at index srcBegin; the last character to
 be copied is at index srcEnd-1. The total number of
 characters to be copied is srcEnd-srcBegin. The
 characters are copied into the subarray of dst starting
 at index dstBegin and ending at index:
 
dstbegin + (srcEnd-srcBegin) - 1
dst is
             null.srcBegin is negative
             dstBegin is negative
             srcBegin argument is greater than
             the srcEnd argument.
             srcEnd is greater than
             this.length().
             dstBegin+srcEnd-srcBegin is greater than
             dst.length
             srcBegin -    start copying at this offset.srcEnd -      stop copying at this offset.dst -         the array to copy the data into.dstBegin -    offset into dst.
