Function Documentation

_Compare_Age()

static bool _Compare_Age ( const EntryInformation *  leftEntry, const EntryInformation *  rightEntry  )

static

Compare the age fields of two EntryInformation objects to determine if the two entries need to be swapped.

Parameters

leftEntry	The left EntryInformation object to compare.
rightEntry	The right EntryInformation object to compare.

Returns

Returns true if the left object comes after the right object in an ascending order and this would need to be swapped; otherwise, returns false.

Definition at line 43 of file Strategy_SortStrategy.c.

_Compare_Height()

static bool _Compare_Height ( const EntryInformation *  leftEntry, const EntryInformation *  rightEntry  )

static

Compare the height fields of two EntryInformation objects to determine if the two entries need to be swapped.

Parameters

leftEntry	The left EntryInformation object to compare.
rightEntry	The right EntryInformation object to compare.

Returns

Returns true if the left object comes after the right object in an ascending order and this would need to be swapped; otherwise, returns false.

_Compare_Name()

static bool _Compare_Name ( const EntryInformation *  leftEntry, const EntryInformation *  rightEntry  )

static

Compare the name fields of two EntryInformation objects to determine if the two entries need to be swapped.

Parameters

leftEntry	The left EntryInformation object to compare.
rightEntry	The right EntryInformation object to compare.

Returns

Returns true if the left object comes after the right object in an ascending order and this would need to be swapped; otherwise, returns false.

SortStrategy_Initialize()

void SortStrategy_Initialize	(	SortStrategy *	strategy,
		SortOptions	sortOption,
		bool	reversedSort
	)

Initialize a SortStrategy object with the desired strategy.

Parameters

strategy	The SortStrategy object to initialize.
sortOption	A value from the SortOptions enumeration specifying the sorting strategy to use.
reversedSort	True if to reverse the sense of the compare function.
