AddEntryL(ThspsDomStringPoolOptimizerEntry &)

void

AddEntryL

(

ThspsDomStringPoolOptimizerEntry &

aEntry

)

Add entry to optimizer list.

Parameters

ThspsDomStringPoolOptimizerEntry & aEntry

Entry to be added.

Close()

void

(

)

Close allocated resources.

Count()

TInt

Count

(

)

Get item count.

Entry(const TInt)

ThspsDomStringPoolOptimizerEntry &

Entry

(

const TInt

aIndex

)

Get entry.

Parameters

const TInt aIndex

Index to Entry.

FindEntry(const TDesC8 &, const TInt, const TInt)

TInt	FindEntry	(	const TDesC8 &	aString,
			const TInt	aLeft,
			const TInt	aRight
		)	[private]

Find entry from alphabetic list. Uses binary search.

Parameters

const TDesC8 & aString	Reference to string to be searched for.
const TInt aLeft	Left limit for binary search
const TInt aRight	Right limit for binary search.

FindInsertionIndexEstimate(const TDesC8 &, const TInt, const TInt)

TInt	FindInsertionIndexEstimate	(	const TDesC8 &	aString,
			const TInt	aLeft,
			const TInt	aRight
		)	[private]

Find a position clue for given string.

Will return index that can be used to initiate linear search. Uses binary search to limit required comparisons when string pools starts to fill.

Note: Returned index is not absolute! it must be only used as a start index for linear searching.

Returned index will be quite close to actual insertion position. it will be 0 - 2 steps backward from actual position.

Parameters

const TDesC8 & aString	Reference to string.
const TInt aLeft	Left limit for binary search
const TInt aRight	Right limit for binary search.

GetIndex(const TDesC8 &)

TInt

GetIndex

(

const TDesC8 &

aString

)

Get index for string.

Parameters

const TDesC8 & aString

Reference to given string.

Reset()

void

Reset

(

)

Reset.
