Member Function Documentation

- (BOOL) ascending

[implementation]

Returns YES if the sort descriptor's order is ascending.

Definition at line 97 of file CPSortDescriptor.j.

- (CPComparisonResult) compareObject:		(id)	lhsObject
withObject:		(id)	rhsObject
				[implementation]

Compares two objects.

Parameters:

	lhsObject	the left hand side object to compre
	rhsObject	the right hand side object to compare

Returns:

the comparison result

Definition at line 125 of file CPSortDescriptor.j.

- (id) initWithKey:		(CPString)	aKey
ascending:		(BOOL)	isAscending
				[implementation]

Initializes the sort descriptor.

Parameters:

	aKey	the property key path to sort
	isAscending	the sort order

Returns:

the initialized sort descriptor

Definition at line 67 of file CPSortDescriptor.j.

- (id) initWithKey:		(CPString)	aKey
ascending:		(BOOL)	isAscending
selector:		(SEL)	aSelector
				[implementation]

Initializes the sort descriptor

Parameters:

	aKey	the property key path to sort
	isAscending	the sort order
	aSelector	this method gets called to compare objects. The method will take one argument (the object to compare against itself, and must return a CPComparisonResult.

Definition at line 79 of file CPSortDescriptor.j.

- (CPString) key

[implementation]

Returns the descriptor's property key

Definition at line 105 of file CPSortDescriptor.j.

- (id) reversedSortDescriptor

[implementation]

Makes a copy of this sort descriptor with a reversed sort order.

Returns:

the reversed copy of the sort descriptor

Definition at line 134 of file CPSortDescriptor.j.

- (SEL) selector

[implementation]

Returns the selector of the method to call when comparing objects.

Definition at line 113 of file CPSortDescriptor.j.
