Methods Summary
abstract boolean	charHasZeroAdvance(int index) Checks if the character doesn't contribute to the text advance param index - character index return true if the character has zero advance
public abstract java.lang.Object	clone()
abstract float	doJustification(TextRunBreaker.JustificationInfo[] jInfos) Performs justification of the segment. Updates positions of individual characters. param jInfos - justification information, gathered by the previous passes return amount of growth or shrink of the segment
abstract void	draw(java.awt.Graphics2D g2d, float xOffset, float yOffset) Renders this text run segment param g2d - graphics to render to param xOffset - X offset from the graphics origin to the origin of the text layout param yOffset - Y offset from the graphics origin to the origin of the text layout
abstract float	getAdvance() Calculates advance of the segment return advance
abstract float	getAdvanceDelta(int start, int end) Calculates advance delta between two characters param start - 1st position param end - 2nd position return advance increment between specified positions
abstract float	getCharAdvance(int index) Returns the advance of the individual character param index - character index return character advance
abstract int	getCharIndexFromAdvance(float advance, int start) Calculates index of the character which advance is equal to the given. If the given advance is greater then the segment advance it returns the position after the last character. param advance - given advance param start - character, from which to start measuring advance return character index
abstract float	getCharPosition(int index) Calculates position of the character on the screen param index - character index return X coordinate of the character position
abstract java.awt.Shape	getCharsBlackBoxBounds(int start, int limit) Creates black box bounds shape for the specified range param start - range sart param limit - range end return black box bounds shape
abstract int	getEnd() Returns end index of the segment return end index
abstract int	getLength() Returns the number of characters in the segment return number of characters
abstract java.awt.geom.Rectangle2D	getLogicalBounds() Returns logical bounds of this segment return logical bounds
abstract java.awt.Shape	getOutline() Returns the outline shape return outline
abstract int	getStart() Returns start index of the segment return start index
abstract java.awt.geom.Rectangle2D	getVisualBounds() Returns visual bounds of this segment return visual bounds
abstract java.awt.font.TextHitInfo	hitTest(float x, float y) Creates text hit info from the hit position param x - X coordinate relative to the origin of the layout param y - Y coordinate relative to the origin of the layout return hit info
abstract void	updateJustificationInfo(TextRunBreaker.JustificationInfo jInfo) Collects justification information into JustificationInfo object param jInfo - JustificationInfo object
