Constructor & Destructor Documentation

◆ ValueRuns() [1/2]

icu::ValueRuns::ValueRuns	(	const le_int32 *	values,
		const le_int32 *	limits,
		le_int32	count
	)

inline

Construct a ValueRuns object from pre-existing arrays of values and limit indices.

Parameters

values	is the address of an array of integer. This array must remain valid until the `ValueRuns` object is destroyed.
limits	is the address of an array of limit indices. This array must remain valid until the `ValueRuns` object is destroyed.
count	is the number of entries in the two arrays.

Stable:: ICU 3.2

Definition at line 671 of file RunArrays.h.

◆ ValueRuns() [2/2]

icu::ValueRuns::ValueRuns ( le_int32 initialCapacity )

Construct an empty ValueRuns object.

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

Parameters

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

virtual

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

Member Function Documentation

◆ add()

le_int32 icu::ValueRuns::add	(	le_int32	value,
		le_int32	limit
	)

Add an integer value 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 ValueRuns object was created with a client-supplied font 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 an integer value 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

value	is the integer value to add
limit	is the limit index to add

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

◆ getDynamicClassID()

virtual UClassID icu::ValueRuns::getDynamicClassID ( void ) const

inlinevirtual

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

◆ getStaticClassID()

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

inlinestatic

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

◆ getValue()

le_int32 icu::ValueRuns::getValue ( le_int32 run ) const

Get the integer value assoicated 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 integer value associated with the given text run.

Stable:: ICU 3.2

◆ grow()

virtual void icu::ValueRuns::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 from icu::RunArray.

◆ init()

virtual void icu::ValueRuns::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.
