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.

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

virtual |
The destructor; virtual so that subclass destructors are invoked as well.
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.
limit | is the limit index to add to the array. |

This is the number of characters in the text.

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.
capacity | is the initial size of the data array. |
Reimplemented in icu::FontRuns, icu::LocaleRuns, and icu::ValueRuns.
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.
capacity | is the initial size of the data array. |
Reimplemented in icu::FontRuns, icu::LocaleRuns, and icu::ValueRuns.
|
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.
Definition at line 247 of file RunArrays.h.

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.
