public ExprModule(java.awt.Point position)
Method Detail

init

public final void init(PointInfo p)
Description copied from class: Module
This method initializes the module in preparation for evaluating the procedure at a new point. The default implementation does nothing. Subclasses whose output depends on the point should override this method.

Overrides:
init in class Module

getAverageValue

public final double getAverageValue(int which,
                                    double blur)
Description copied from class: Module
Get the average value of the specified output port. If the specified output port does not have a value type of NUMBER, the result is undefined. Blur specifies the amount of smoothing to use. Subclasses which can return values should override this method.

Overrides:
getAverageValue in class Module

getValueError

public final double getValueError(int which,
                                  double blur)
Description copied from class: Module
Get the uncertainty in the value of the specified output port. If the specified output port does not have a value type of NUMBER, the result is undefined. Blur specifies the amount of smoothing to use. Subclasses which can return values should override this method.

Overrides:
getValueError in class Module

getValueGradient

public final void getValueGradient(int which,
                                   Vec3 grad,
                                   double blur)
Description copied from class: Module
Get the gradient of the value of the specified output port. If the specified output port does not have a value type of NUMBER, the result is undefined. Blur specifies the amount of smoothing to use. Subclasses which can return values should override this method.

Overrides:
getValueGradient in class Module

setInput

public void setInput(IOPort which,
                     IOPort port)
Description copied from class: Module
Specify the module and port which one of the input ports is connected to.

Overrides:
setInput in class Module

edit

public boolean edit(ProcedureEditor editor,
                    Scene theScene)
Description copied from class: Module
This is an old form of edit() that exists only to maintain compatibility with old plugins. Subclasses should override the other form, not this one.

Overrides:
edit in class Module

duplicate

public Module duplicate()
Description copied from class: Module
Create a duplicate of this module. Subclasses with adjustable parameters should override this.

Overrides:
duplicate in class Module

writeToStream

public void writeToStream(java.io.DataOutputStream out,
                          Scene theScene)
                   throws java.io.IOException
Description copied from class: Module
Write out the module's parameters to an output stream. Subclasses with editable parameters should override this method.

Overrides:
writeToStream in class Module
Throws:
java.io.IOException

setExpr

public void setExpr(java.lang.String e)

readFromStream

public void readFromStream(java.io.DataInputStream in,
                           Scene theScene)
                    throws java.io.IOException
Description copied from class: Module
Read in the module's parameters from an input stream. Subclasses with editable parameters should override this method.

Overrides:
readFromStream in class Module
Throws:
java.io.IOException

isCompiled

public final boolean isCompiled()
