Class FilterPolygonForSmallLines

java.lang.Object
  org.shapelogic.polygon.FilterPolygonForSmallLines

All Implemented Interfaces:

Calc0<Polygon>, CalcInvoke<Polygon>, CalcValue<Polygon>, LazyCalc<Polygon>, Improver<Polygon>

public class FilterPolygonForSmallLines
extends java.lang.Object
implements Improver<Polygon>

Take a polygon as input and a list of sets of point that potentially can be combined. Create a new polygon. I think that if there have been no changes then just return the original polygon. I think that polygons are supposed to be immutable.

Constructor Summary

FilterPolygonForSmallLines()

FilterPolygonForSmallLines(Polygon inputPolygon)

Method Summary

boolean	createdNewVersion()
Polygon	getInput()
Polygon	getValue() Starts a lazy calculation.
protected void	handleLine(CLine line) I think that this need to be done differently for different types of polygons For Polygon: Just go through lines and filter For MultiLinePolygon: Run through both multi lines and independent lines How do I get this unified? Change so they have the same interface so now Polygon also return independent lines.
Polygon	invoke()
boolean	isDirty() When dirty is false that means that the calculated value can be used
void	setInput(Polygon input)
void	setup() Currently not super well define used for 2 purposes: Reset: called from the outside if you want to reuse it init: Called from the inside when calculation start to have everything setup maybe the semantic could work for both? TODO: This should be separated better.

Method Detail

getInput

public Polygon getInput()

Specified by:

getInput in interface Improver<Polygon>

isDirty

public boolean isDirty()

Description copied from interface: LazyCalc

When dirty is false that means that the calculated value can be used

Specified by:

isDirty in interface LazyCalc<Polygon>

setup

public void setup()

Description copied from interface: LazyCalc

Currently not super well define used for 2 purposes: Reset: called from the outside if you want to reuse it init: Called from the inside when calculation start to have everything setup maybe the semantic could work for both? TODO: This should be separated better.

Specified by:

setup in interface LazyCalc<Polygon>

invoke

public Polygon invoke()

Specified by:

invoke in interface Calc0<Polygon>

getValue

public Polygon getValue()

Description copied from interface: CalcValue

Starts a lazy calculation. If dirty do calc() else return cached value. This should maybe be moved up in the hierarchy

Specified by:

getValue in interface CalcValue<Polygon>

handleLine

protected void handleLine(CLine line)

I think that this need to be done differently for different types of polygons For Polygon: Just go through lines and filter For MultiLinePolygon: Run through both multi lines and independent lines How do I get this unified? Change so they have the same interface so now Polygon also return independent lines. This can be optimized

createdNewVersion

public boolean createdNewVersion()

Specified by:

createdNewVersion in interface Improver<Polygon>

setInput

public void setInput(Polygon input)

Specified by:

setInput in interface Improver<Polygon>
