Constructor Detail

TextChunkLocationDefaultImp

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

Method Detail

orientationMagnitude

public int orientationMagnitude()

Specified by:

orientationMagnitude in interface LocationTextExtractionStrategy.ITextChunkLocation

distPerpendicular

public int distPerpendicular()

Specified by:

distPerpendicular in interface LocationTextExtractionStrategy.ITextChunkLocation

distParallelStart

public float distParallelStart()

Specified by:

distParallelStart in interface LocationTextExtractionStrategy.ITextChunkLocation

distParallelEnd

public float distParallelEnd()

Specified by:

distParallelEnd in interface LocationTextExtractionStrategy.ITextChunkLocation

getStartLocation

public Vector getStartLocation()

Specified by:

getStartLocation in interface LocationTextExtractionStrategy.ITextChunkLocation

Returns:

the start location of the text

getEndLocation

public Vector getEndLocation()

Specified by:

getEndLocation in interface LocationTextExtractionStrategy.ITextChunkLocation

Returns:

the end location of the text

getCharSpaceWidth

public float getCharSpaceWidth()

Specified by:

getCharSpaceWidth in interface LocationTextExtractionStrategy.ITextChunkLocation

Returns:

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

sameLine

public boolean sameLine(LocationTextExtractionStrategy.ITextChunkLocation as)

Specified by:

sameLine in interface LocationTextExtractionStrategy.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(LocationTextExtractionStrategy.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 LocationTextExtractionStrategy.ITextChunkLocation

Parameters:

other -

Returns:

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

isAtWordBoundary

public boolean isAtWordBoundary(LocationTextExtractionStrategy.ITextChunkLocation previous)

Specified by:

isAtWordBoundary in interface LocationTextExtractionStrategy.ITextChunkLocation

compareTo

public int compareTo(LocationTextExtractionStrategy.ITextChunkLocation other)

Specified by:

compareTo in interface Comparable<LocationTextExtractionStrategy.ITextChunkLocation>
