Member Function Documentation

- (BOOL) addGetField:		(NSString *)	fieldName
withType:		(enum JDDATATYPE)	dataType

Adds a get style field to the Field array. A get style field has nothing in the value field. This type of field is what is provided to a getEntries call to the database manager

Parameters:

	fieldName	Name of the field in the database
	dataType	type of data (e.g. TEXT/INTEGER)

Returns:

True on success False on failure

- (BOOL) addSetField:		(NSString *)	fieldName
withValue:		(NSObject *)	value
withType:		(enum JDDATATYPE)	dataType

Adds a set style field to the Field array. A get style field has a value set value field. This type of field is what is provided to a add/setEntries call to the database manager. a getEntries call returns this a JDFieldArray with this type of set

Parameters:

	fieldName	Name of the field in the database
	value	Some object (NSString, or NSNumber) to add to associate with this field.
	dataType	type of data (e.g. TEXT/INTEGER)

Returns:

True on success False on failure

- (void) changeValueFor:		(NSString *)	field
toObject:		(NSObject *)	object

Changes the value for a value in this field array. This has assorted uses from modifying values just pulled from the database for update and reentry or for dynamiclly updating otherwise static data. The latter case is not recommended unless you know what you're doing.

Parameters:

	field	Name of the field to update
	object	New object to replace (note, cannot change data type)

- (NSString *) getFieldAt:

(unsigned long)

index

Gets the name of a field at the given index

Parameters:

index

the index to get the value at

Returns:

the string representing the field name for this index

- (long) getTypeAt:

(unsigned long)

index

Gets the type of a field at the given index

Parameters:

index

the index to get the type at

Returns:

the value corresponding to the JDDATATYPE for the field at the indexed location

- (NSObject *) getValueAt:

(unsigned long)

index

Gets the value object of a field at the given index

Parameters:

(unsigned

long) index the index to get the value at

Returns:

(NSObject *) the object for the value for this index

- (NSObject *) getValueFor:

(NSString *)
