CountRuns()

size_t ICUParagraphLayout::ICULine::CountRuns ( ) const

inlineoverridevirtual

Get the number of runs in this line.

Returns

The number of runs.

int ICUParagraphLayout::ICULine::GetInternalCharLength ( char32_t c ) const

inlineoverridevirtual

Get the number of elements the given character occupies in the underlying text buffer of the Layouter.

Many use UTF-16 internally, meaning a character larger than MAX_UINT16 occupies two places in its buffer.

c	The character to get the length for.

Returns

The length.

overridevirtual

Get the height of the line.

Returns

The maximum height of the line.

Implements ParagraphLayouter::Line.

GetVisualRun()

const VisualRun & ICUParagraphLayout::ICULine::GetVisualRun ( size_t run ) const

inlineoverridevirtual

Get a reference to the given run.

Parameters

run	The index into the runs.

Returns

The reference to the run.
