If the advances of 0N/A * all characters do not exceed width, return getNumCharacters. If width is 0N/A * less than zero, return logicalStart - 1. 0N/A * Return the accumulated advances of all characters between logicalStart and 0N/A * Return whether a caret can exist on the leading edge of the 0N/A * character at offset. If the character is part of a ligature 0N/A * (for example) a caret may not be appropriate at offset. 0N/A * A convenience overload of getCharVisualBounds that defaults the label origin 0N/A * Return the number of justification records this uses. 0N/A * Return GlyphJustificationInfo objects for the characters between 0N/A * charStart and charLimit, starting at offset infoStart. Infos 0N/A * will be in visual order. All positions between infoStart and 0N/A * getNumJustificationInfos will be set. If a position corresponds 0N/A * to a character outside the provided range, it is set to null. 0N/A * Apply deltas to the data in this component, starting at offset 0N/A * deltaStart, and return the new component. There are two floats 0N/A * for each justification info, for a total of 2 * getNumJustificationInfos. 0N/A * The first delta is the left adjustment, the second is the right 0N/A * If flags[0] is true on entry, rejustification is allowed. If 0N/A * the new component requires rejustification (ligatures were 0N/A * formed or split), flags[0] will be set on exit.
