Definition: crc.h:76
virtual unsigned int width(bool constrained=false) const
How many bytes does this use Return the number of bytes of storage this variable uses. For scalar types, this is pretty simple (an int32 uses 4 bytes, etc.). For arrays and Constructors, it is a bit more complex. Note that a scalar String variable uses sizeof(String*) bytes, not the length of the string. In other words, the value returned is independent of the type. Also note width() of a String array returns the number of elements in the array times sizeof(String*). That is, each different array size is a different data type.
