LLongComparator()

Purpose:

The constructor is a placeholder, it doesn't do anything for this class.

Access:

Public

Prototype:

LLongComparator();

None

~LLongComparator()

Purpose:

The destructor is a placeholder, it doesn't do anything for this class.

Access:

Virtual, Public

Prototype:

~LLongComparator();

Clone()

Purpose:

This method behaves identically to Clone() in the base class LComparator.

Compare()

Purpose:

This method compares the contents of the two items to determine the comparison value.

Access:

Virtual, Public

Prototype:

virtual SInt32 Compare(

const void* inItemOne,

const void* inItemTwo,

UInt32 inSizeOne,

UInt32 inSizeTwo) const;

This method has the following parameters:

const void*	inItemOne	A data pointer to the first item.
const void*	inItemTwo	A data pointer to the second item.
UInt32	inSizeOne	Unused
UInt32	inSizeTwo	Unused

Return:

SInt32 that indicates one of the following:

• < 0 - object/data item 1 is less than object/data item 2
• 0 - object/data item 1 is equal to object/data item 2
• > 0 -þobject/data item 1 is greater than object/data item 2

GetComparator()

Purpose:

This method behaves identically to GetComparator() in the base class LComparator.

IsEqualTo()

Purpose:

This method detects whether two objects are equal.

Access:

Virtual, Public

Prototype:

virtual Boolean IsEqualTo(

 const void* inItemOne,

 const void* inItemTwo,

 UInt32 inSizeOne,

 UInt32 inSizeTwo) const;

This method has the following parameters:

const void*	inItemOne	A data pointer to the first item.
const void*	inItemTwo	A data pointer to the second item.
UInt32	inSizeOne	Unused
UInt32	inSizeTwo	Unused

Return:

Boolean indicating true if the items are equal, false otherwise.

sLongComparator

Purpose:

This data member stores the pointer to the comparison "standard" object.

Access:

Protected

Prototype:

static LLongComparator* sLongComparator;
