Method Detail

setGeometry

public void setGeometry(PgGeometry geom)

Assign a geometry on which this workshop operates, and create a backup copy if workshop is cancelled. Subclasses frequently overwrite this method but are adviced to call this method.

Specified by:

setGeometry in interface PjWorkshopIf

Overrides:

setGeometry in class PjWorkshop

Parameters:

geom - the workshop modifies this geometry.

getFunction

public java.lang.String getFunction()

Get textual expression of level function.

setFunction

public void setFunction(java.lang.String s)

Set textual expression of level function used clipping from outside of workshop. String must be a valid mathematical function in variables {u,v,w} where the number of variables must be equal to the vertex dimension of the geometry to which clipping is applied.

Parameters:

s - string containing a function expression

Parser

getLevel

public double getLevel()

Get level value at which clipping happens.

Returns:

level value at which clipping happens

setLevel

public void setLevel(double level)

Set the value at which clipping happens.

Parameters:

level - level value at which clipping happens

update

public boolean update(java.lang.Object event)

Update the class whenever a child has changed. Method is usually invoked from the children.

Specified by:

update in interface PsUpdateIf

Overrides:

update in class PjWorkshop

Parameters:

event - sender of this update.

Returns:

true if update was correctly handled by superclass.

intersectWithFunction

public void intersectWithFunction()

Invoke Cutting the elements of the workshop's geometry at the level function.

splitAtFunction

public PgElementSet splitAtFunction()

Split the workshop's geometry into two geometries along the level function. The workshop's geometry will contain all areas with function values lower than the cutting level, the returned geometry contains all other areas.

clipAtFunction

public void clipAtFunction(boolean bPositive)

Clip the workshop's geometry at the level function.

Parameters:

bPositive - Flag to get either the higher or the lower function value areas.
