Interface primitives.machines.FunctionalLinkage

public interface FunctionalLinkage
extends MachineListener
This interface declares the methods defining a functional linkage. A functional linkage is a machine which can compute functions. given the locations of "input" joints the result is given by the location of the "output" joint.An object declared as a FunctionalLinkage can be a Machine or a composition of composed objects of FunctionalLinkage.

Methods

o forceInputJoints 
 public abstract Coordinate[] forceInputJoints(Coordinate inputs[])
Forces the input joints to be moved to the specified locations. If the specifeid location is not valid then this object should implement a resizing of the machine such that the specified locations should be valid.

Parameters:
inputs - an array of the required input joints locations. The size of the array is implementation specific.
o getOutputJoints 
 public abstract Coordinate[] getOutputJoints()
Returns:
an array of the locations of the output joints. the size of the array is implementation specific.
o getInputJoints 
 public abstract Coordinate[] getInputJoints()
Returns:
an array of the locations of the input joints. the size of the array is implementation specific.
o setInputJoints 
 public abstract Coordinate[] setInputJoints(Coordinate inputJoints[]) throws MachineException
changes the state of the machine by moving the location of the input joints.

Parameters:
inputJoints - an array of the required locations. The size of the array is implementation specific.
Returns:
an array of the new locations of the output joints.
Throws: MachineException
if the required locations are not valid. If the implementation must accept the locations use < a href="#forceInputJoints">forceInputJoints
o getParameters 
 public abstract double[] getParameters()
Returns:
an array of parameters specific to every implementation.
See Also:
setParameters
o setParameters 
 public abstract void setParameters(double parameters[]) throws MachineException
Request the implementation to change its parameters.

Parameters:
parameters - an implementation specific array of parameters.
Throws: MachineException
if the required parametrs are not acceptable by the implementation.
o mouseMoved 
 public abstract int mouseMoved(MouseEvent m)
A method which controls mouse move user requests.

Parameters:
m - the mouseEvent object specifying location of the mouse pointer.
Returns:
the enumerated joint the the mouse pointer is over or 0 if the mouse pointer is elsewhere.
o mouseDragged 
 public abstract void mouseDragged(MouseEvent m) throws MachineException
A method which controls mouse darg user requests.

Parameters:
m - the mouseEvent object specifying location of the mouse pointer.
Throws: MachineException
if the new location requested is declared not valid by the specific implementation.
o getActiveStr 
 public abstract String getActiveStr(int activeJoint)
Returns a String to be displayed.

Parameters:
activeJoint - dispalys the enumerated string usualy associated with a joint.
o getActiveJoint 
 public abstract int getActiveJoint()
Returns:
the enumerated joint the mouse pointer is over(0 value indicates the mouse pointer is located elsewhere)
See Also:
mouseMoved
o setActiveJoint 
 public abstract void setActiveJoint(int activeJoint)
Sets the activeJoint.

Parameters:
activeJoint - the joint to set.
