DIACRITICAL_MARKS_ALLOWED_VERTICAL_DEVIATION

private static final float DIACRITICAL_MARKS_ALLOWED_VERTICAL_DEVIATION

Constant Field Values

startLocation

private final Vector startLocation

The starting location of the chunk.

endLocation

private final Vector endLocation

The ending location of the chunk.

orientationVector

private final Vector orientationVector

Unit vector in the orientation of the chunk.

orientationMagnitude

private final int orientationMagnitude

The orientation as a scalar for quick sorting.

distPerpendicular

private final int distPerpendicular

Perpendicular distance to the orientation unit vector (i.e. the Y position in an unrotated coordinate system). We round to the nearest integer to handle the fuzziness of comparing floats.

distParallelStart

private final float distParallelStart

Distance of the start of the chunk parallel to the orientation unit vector (i.e. the X position in an unrotated coordinate system).

distParallelEnd

private final float distParallelEnd

Distance of the end of the chunk parallel to the orientation unit vector (i.e. the X position in an unrotated coordinate system).

charSpaceWidth

private final float charSpaceWidth

The width of a single space character in the font of the chunk.

Constructor Detail

TextChunkLocationDefaultImp

public TextChunkLocationDefaultImp(Vector startLocation,
                                   Vector endLocation,
                                   float charSpaceWidth)

Method Detail

orientationMagnitude

public int orientationMagnitude()

Specified by:

orientationMagnitude in interface ITextChunkLocation

distPerpendicular

public int distPerpendicular()

Specified by:

distPerpendicular in interface ITextChunkLocation

distParallelStart

public float distParallelStart()

Specified by:

distParallelStart in interface ITextChunkLocation

distParallelEnd

public float distParallelEnd()

Specified by:

distParallelEnd in interface ITextChunkLocation

getStartLocation

public Vector getStartLocation()

Specified by:

getStartLocation in interface ITextChunkLocation

Returns:

the start location of the text

getEndLocation

public Vector getEndLocation()

Specified by:

getEndLocation in interface ITextChunkLocation

Returns:

the end location of the text

getCharSpaceWidth

public float getCharSpaceWidth()

Specified by:

getCharSpaceWidth in interface ITextChunkLocation

Returns:

the width of a single space character as rendered by this chunk

sameLine

public boolean sameLine(ITextChunkLocation as)

Specified by:

sameLine in interface ITextChunkLocation

Parameters:

as - the location to compare to

Returns:

true is this location is on the the same line as the other

distanceFromEndOf

public float distanceFromEndOf(ITextChunkLocation other)

Computes the distance between the end of 'other' and the beginning of this chunk in the direction of this chunk's orientation vector. Note that it's a bad idea to call this for chunks that aren't on the same line and orientation, but we don't explicitly check for that condition for performance reasons.

Specified by:

distanceFromEndOf in interface ITextChunkLocation

Parameters:

other -

Returns:

the number of spaces between the end of 'other' and the beginning of this chunk

isAtWordBoundary

public boolean isAtWordBoundary(ITextChunkLocation previous)

Specified by:

isAtWordBoundary in interface ITextChunkLocation

containsMark

static boolean containsMark(ITextChunkLocation baseLocation,
                            ITextChunkLocation markLocation)
