Constructor & Destructor Documentation

◆ LocaleRuns() [1/2]

icu::LocaleRuns::LocaleRuns	(	const Locale **	locales,
		const le_int32 *	limits,
		le_int32	count
	)

inline

Construct a LocaleRuns object from pre-existing arrays of locales and limit indices.

Parameters

locales	is the address of an array of pointers to `Locale` objects. This array, and the `Locale` objects to which it points, must remain valid until the `LocaleRuns` object is destroyed.
limits	is the address of an array of limit indices. This array must remain valid until the `LocaleRuns` object is destroyed.
count	is the number of entries in the two arrays.

◆ LocaleRuns() [2/2]

icu::LocaleRuns::LocaleRuns ( le_int32 initialCapacity )

Construct an empty LocaleRuns object.

Clients can add locale and limit indices arrays using the add method.

Parameters

initialCapacity is the initial size of the locale and limit indices arrays. If this value is zero, no arrays will be allocated.

Member Function Documentation

◆ add()

le_int32 icu::LocaleRuns::add	(	const Locale *	locale,
		le_int32	limit
	)

Add a Locale and limit index pair to the data arrays and return the run index where the data was stored.

This method calls RunArray::add(limit) which will create or grow the arrays as needed.

If the LocaleRuns object was created with a client-supplied locale and limit indices arrays, this method will return a run index of -1.

Subclasses should not override this method. Rather they should provide a new add method which takes a locale and a limit index along with whatever other data they implement. The new add method should first call this method to grow the font and limit indices arrays, and use the returned run index to store data their own arrays.

Parameters

locale	is the address of the `Locale` to add. This object must remain valid until the `LocaleRuns` object is destroyed.
limit	is the limit index to add

Returns: the run index where the locale and limit index were stored, or -1 if the data cannot be stored.

◆ getDynamicClassID()

UClassID icu::LocaleRuns::getDynamicClassID ( ) const

inlineoverridevirtual

ICU "poor man's RTTI", returns a UClassID for the actual class.

Stable:: ICU 3.2

Reimplemented from icu::UObject.

Definition at line 501 of file RunArrays.h.

◆ getLocale()

const Locale * icu::LocaleRuns::getLocale ( le_int32 run ) const

Get the Locale object associated with the given run of text.

Use RunArray::getLimit(run) to get the corresponding limit index.

Parameters

run	is the index into the font and limit indices arrays.

Returns: the Locale associated with the given text run.

◆ grow()

void icu::LocaleRuns::grow ( le_int32 capacity )

overrideprotectedvirtual

Grow a data array to the given initial size.

This method will be called by the add method if the limit indices array is full. Subclasses which override this method must also call it from the overriding method to grow the limit indices array.

Parameters

capacity is the initial size of the data array.

See also: add

Stable:: ICU 3.2

Reimplemented from icu::RunArray.

◆ init()

void icu::LocaleRuns::init ( le_int32 capacity )

overrideprotectedvirtual

Create a data array with the given initial size.

This method will be called by the add method if there is no limit indices array. Subclasses which override this method must also call it from the overriding method to create the limit indices array.

Parameters

capacity is the initial size of the data array.
