The Struct class is provided for handling compound structure Values.
Note that Struct inherits from Value which implements many of its methods. The following table describes methods specialized for the Struct subclass:
| in compare( Value * x ) | Compare the current Value of this Struct with the argument x and return an integer value indicating the result of the comparison: a negative integer value if this is less than x, zero if they are equal, and a positive integer value if this is greater than x |
| Value * get( int index ) | Get the component of this Struct with the specified index |
| int nComponents( void ) | Get the number of components in this Struct |
| size_t serialize( char * buf , size_t & size ) | Serialize the current Struct to the specified buffer |
| void set( int index, Value * val ) | Set the new Value of the component of this Struct with the specified index |
| Struct* source( void ) | Get a pointer to the underlying database Struct; this method may be used to distinguish tuples created by an SQL select statement from Struct and Record instances corresponding to database records |
| size_t toString( char * buf , size_t & size ) | Serialize the current Value to the specified buffer; only size bytes are copied (Note that if the terminating null does not fit in size bytes, the resulting buffer will NOT be null-terminated) |
| Type type( void ) | Get the Value type |
| Value * updateAt( int index ) | Get the structure or array element with the specified index for update; returns the Value of the component that will be updated |
