Constructor Detail

TextChunk

public TextChunk(java.lang.String string,
                 Vector startLocation,
                 Vector endLocation,
                 float charSpaceWidth)

TextChunk

public TextChunk(java.lang.String string,
                 LocationTextExtractionStrategy.TextChunkLocation loc)

Method Detail

getText

public java.lang.String getText()

Returns:

the text captured by this chunk

getLocation

public LocationTextExtractionStrategy.TextChunkLocation getLocation()

Returns:

an object holding location data about this TextChunk

getStartLocation

public Vector getStartLocation()

Returns:

the start location of the text

getEndLocation

public Vector getEndLocation()

Returns:

the end location of the text

getCharSpaceWidth

public float getCharSpaceWidth()

Returns:

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

distanceFromEndOf

public float distanceFromEndOf(LocationTextExtractionStrategy.TextChunk 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.

Parameters:

other - the other LocationTextExtractionStrategy.TextChunk

Returns:

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

printDiagnostics

private void printDiagnostics()

compareTo

public int compareTo(LocationTextExtractionStrategy.TextChunk rhs)

Compares based on orientation, perpendicular distance, then parallel distance

Specified by:

compareTo in interface java.lang.Comparable<LocationTextExtractionStrategy.TextChunk>

Parameters:

rhs - the other object

sameLine

private boolean sameLine(LocationTextExtractionStrategy.TextChunk lastChunk)
