Detailed Description

The RunArray class is a base class for building classes which represent data that is associated with runs of text.

This class maintains an array of limit indices into the text, subclasses provide one or more arrays of data.

Constructor & Destructor Documentation

◆ RunArray() [1/2]

icu::RunArray::RunArray	(	const le_int32 *	limits,
		le_int32	count
	)

inline

Construct a RunArray object from a pre-existing array of limit indices.

Parameters

limits	is an array of limit indices. This array must remain valid until the `RunArray` object is destroyed.
count	is the number of entries in the limit array.

Stable:: ICU 3.2

Definition at line 236 of file RunArrays.h.

◆ RunArray() [2/2]

icu::RunArray::RunArray ( le_int32 initialCapacity )

Construct an empty RunArray object.

Clients can add limit indices array using the add method.

Parameters

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

◆ ~RunArray()

virtual icu::RunArray::~RunArray ( )

virtual

The destructor; virtual so that subclass destructors are invoked as well.

Member Function Documentation

◆ add()

le_int32 icu::RunArray::add ( le_int32 limit )

Add a limit index to the limit indices array and return the run index where it was stored.

If the array does not exist, it will be created by calling the init method. If it is full, it will be grown by calling the grow method.

If the RunArray object was created with a client-supplied limit indices array, 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 limit index along with whatever other data they implement. The new add method should first call this method to grow the data arrays, and use the return value to store the data in their own arrays.

Parameters

limit is the limit index to add to the array.

Returns: the run index where the limit index was stored, or -1 if the limit index cannot be stored.

See also: init; grow

Stable:: ICU 3.2

◆ getCount()

le_int32 icu::RunArray::getCount ( ) const

inline

Get the number of entries in the limit indices array.

Returns: the number of entries in the limit indices array.

Stable:: ICU 3.2

Definition at line 242 of file RunArrays.h.

◆ getDynamicClassID()

UClassID icu::RunArray::getDynamicClassID ( ) const

inlineoverridevirtual

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

Stable:: ICU 3.2

Reimplemented from icu::UObject.

Reimplemented in icu::ValueRuns.

Definition at line 164 of file RunArrays.h.

◆ getLimit() [1/2]

le_int32 icu::RunArray::getLimit ( ) const

inline

Get the last limit index.

This is the number of characters in the text.

Returns: the last limit index.

◆ getLimit() [2/2]

le_int32 icu::RunArray::getLimit ( le_int32 run ) const

inline

Get the limit index for a particular run of text.

Parameters

run	is the run. This is an index into the limit index array.

Returns: the limit index for the run, or -1 if run is out of bounds.

Stable:: ICU 3.2

Definition at line 252 of file RunArrays.h.

◆ getStaticClassID()

static UClassID icu::RunArray::getStaticClassID ( )

inlinestatic

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

Stable:: ICU 3.2

Definition at line 157 of file RunArrays.h.

◆ grow()

virtual void icu::RunArray::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

capacity is the initial size of the data array.

See also: add

Stable:: ICU 3.2

Reimplemented in icu::FontRuns, icu::LocaleRuns, and icu::ValueRuns.

◆ init()

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

protectedvirtual

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.

See also: add

Stable:: ICU 3.2

Reimplemented in icu::FontRuns, icu::LocaleRuns, and icu::ValueRuns.

◆ reset()

void icu::RunArray::reset ( )

inline

Reset the limit indices array.

This method sets the number of entries in the limit indices array to zero. It does not delete the array.

Note: Subclass arrays will also be reset and not deleted.

Field Documentation

◆ fClientArrays

le_bool icu::RunArray::fClientArrays

protected

Set by the constructors to indicate whether or not the client supplied the data arrays.

If they were supplied by the client, the add method won't change the arrays and the destructor won't delete them.
