Class SortOrdering

The canonical sorting command has a key and an operator. The key is the name of the attribute to use for sorting objects, the operator is the sorting order (e.g. ascending, descending). Note: the key is in fact more general than simply the name of an, attribute, since objects' values are accessed through L{KeyValueCoding} --see L{sortedArrayUsingKeyOrderArray}.

Method Summary
	`__init__(self, key, operator)`
	`key(self)`
	`operator(self)`
	`sortedArrayUsingKeyOrderArray(array, sortOrderings)` Sorts array with respect to the list of sort commands supplied in sortOrderings. (Static method)
	`sortOrderingWithKey(key, operator)` Alternate constructor for a L{SortOrdering} (Static method)

Class Variable Summary
`tuple`	`__implements__` = `(<class Modeling.interfaces.SortOrderin...`

Static Method Details

sortedArrayUsingKeyOrderArray(array, sortOrderings)

Sorts array with respect to the list of sort commands supplied in sortOrderings. Object's values are accessed using L{SortOrdering}.key and L{KeyValueCoding.valueForKeyPath}.

@parameter array: a sequence of objects implementing: L{KeyValueCoding.KeyValueCoding.valueForKeyPath}

@parameter sortOrderings: a sequence of L{SortOrdering} commands.

@return: the sorted array

sortOrderingWithKey(key, operator)

Alternate constructor for a L{SortOrdering}
