Method Detail

setGeometry

public void setGeometry(PgGeometry geom)

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

Specified by:

setGeometry in interface PjWorkshopIf

Overrides:

setGeometry in class PjWorkshop

Parameters:

geom - the workshop modifies this geometry.

setMode

public void setMode(int mode)

Set intersection mode to FUNCTION or DATA.

Specified by:

setMode in interface PjWorkshopIf

Overrides:

setMode in class PjWorkshop

Parameters:

mode - either MODE_STANDARD for standard mode, or MODE_BUG for debugging operations.

See Also:

PjWorkshopIf.MODE_STANDARD

getMode

public int getMode()

Get current intersection mode

Overrides:

getMode in class PjWorkshop

Returns:

either MODE_STANDARD for standard mode, or another mode.

See Also:

PjWorkshopIf.MODE_STANDARD

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

setScalarData

public void setScalarData(PdVector data)

Set double data to clip or split Geometry at.

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.

See Also:

PsObject.setParent(PsUpdateIf), PsObject.getFather(), PsObject.addUpdateListener(PsUpdateIf)

intersect
