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

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

Get the integer value associated with the given run of text.
Use RunArray::getLimit(run)
to get the corresponding limit index.
run | is the index into the font and limit indices arrays. |
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 from icu::RunArray.
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. |
