Detailed Description

template<size_t buff_sz>
class StringBuffer< buff_sz >

String class wrapper with a preallocated buffer of size buff_sz

This class allows to replace sequences of: char buff[12345]; String str(buff, sizeof(buff)); str.length(0); with a simple equivalent declaration: StringBuffer<12345> str;
