The Field class represents a field in a database record (object or instance of a database class).
The Field methods are listed below.
| size_t calculateStructAlignment( void ) | Calculate the struct alignment |
| Iterator <Field>* components( void ) | Get a field iterator for a struct Field |
| Field* element( void ) | Get a field descriptor for an element of an array (vector) Field |
| Type elementType( void ) | Get the type of an element of an array (vector) Field |
| Field* findField( String * name ) | Find the component in this struct Field by name. |
| int fixedSize( void ) | Get the size of fixed arrays (Note: for fixed-size array Fields only) |
| Value* get( Struct rec ) | Get the value of this Field: the record or structure containing this Field (In most cases rec is just a table record - even for components or columns of this record having type struct. For components of array of struct elements, rec should be the Struct Value returned for this array element) |
| bool isAutoGenerated( void ) | Check if this Field is an autogenerated column and should not be considered in a “natural” join |
| String* name( void ) | Get the name of this Field |
| String* referencedTableName( void ) | Get the name of this referenced table if this is a reference Field (Note that this method is only for reference Fields) |
| Field* scope( void ) | Get the scope of the Field if it’s part of a struct or array field; returns the struct or array Field of which this Field is a component, or NULL if this Field is not a component of any struct or array |
| size_t serialize( char * buf , size_t & size ) | Serialize the current Field value to the specified buffer |
| void set( Struct * rec, Value * val ) | Set the new Value of this Field |
| Table* set( void ) | Get the Table this Field belongs to |
| Type type( void ) | Get the Type of this Field |
| Value* update( Struct * rec ) | Get the struct or array Value of this Field for update |
