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
localesis 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.
limitsis the address of an array of limit indices. This array must remain valid until the LocaleRuns object is destroyed.
countis the number of entries in the two arrays.
Stable:
ICU 3.2

Definition at line 537 of file RunArrays.h.

◆ 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
initialCapacityis 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
localeis the address of the Locale to add. This object must remain valid until the LocaleRuns object is destroyed.
limitis 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()

virtual UClassID icu::LocaleRuns::getDynamicClassID ( void  ) const
inlinevirtual

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

Stable:
ICU 3.2

Reimplemented from icu::RunArray.

Definition at line 501 of file RunArrays.h.

References icu::FontRuns::getStaticClassID(), icu::FontRuns::grow(), and icu::FontRuns::init().

◆ getLocale()

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

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

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

Parameters
runis the index into the font and limit indices arrays.
Returns
the Locale associated with the given text run.

static UClassID icu::LocaleRuns::getStaticClassID ( void  )

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

◆ grow()

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

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
capacityis the initial size of the data array.

◆ init()

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

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
capacityis the initial size of the data array.
