Method Detail

setCheckingBasicTopology

public void setCheckingBasicTopology(boolean checkingBasicTopology)

Sets whether basic JTS validation should be performed

Parameters:

checkingBasicTopology - whether basic JTS validation should be performed

setCheckingNoRepeatedConsecutivePoints

public void setCheckingNoRepeatedConsecutivePoints(boolean checkingNoRepeatedConsecutivePoints)

Sets whether consecutive points are not allowed to be the same

Parameters:

checkingNoRepeatedConsecutivePoints - whether consecutive points are not allowed to be the same

setCheckingNoHoles

public void setCheckingNoHoles(boolean checkingNoHoles)

Sets whether polygons are not allowed to have holes

Parameters:

checkingNoHoles - whether polygons are not allowed to have holes

setCheckingPolygonOrientation

public void setCheckingPolygonOrientation(boolean checkingPolygonOrientation)

See Also:

setCheckingMinAngle(boolean)

setMinPolygonArea

public void setMinPolygonArea(double minPolygonArea)

Sets the area below which the minimum-polygon-area check will raise a validation error.

Parameters:

minPolygonArea - the threshould used by the minimum-polygon-area check

See Also:

setCheckingMinPolygonArea(boolean)
