Construct a FontRuns
object from pre-existing arrays of fonts and limit indices.
fonts | is the address of an array of pointers to LEFontInstance objects. This array, and the LEFontInstance objects to which it points must remain valid until the FontRuns object is destroyed. |
limits | is the address of an array of limit indices. This array must remain valid until the FontRuns object is destroyed. |
count | is the number of entries in the two arrays. |

le_int32 icu::FontRuns::add | ( | const LEFontInstance * | font, |
le_int32 | limit | ||
) |
Add an LEFontInstance
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 FontRuns
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 a font 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.
font | is the address of the LEFontInstance to add. This object must remain valid until the FontRuns object is destroyed. |
limit | is the limit index to add |

const LEFontInstance * icu::FontRuns::getFont | ( | le_int32 | run | ) | const |
Get the LEFontInstance
object 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. |
LEFontInstance
associated with the given text run.ICU "poor man's RTTI", returns a UClassID for this class.

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. |
