Polygon

protected Polygon(ConstraintSolver cs,
                  int id)

Method Detail

hasDefaultDomain

public boolean hasDefaultDomain()

Returns whether or not the domain of this Polygon has been refined.

Returns:

true iff the domain of this Polygon has been refined.

setMovable

public void setMovable(boolean isMovable)

Set whether this Polygon is movable.

Parameters:

isMovable - Whether this Polygon is movable.

isMovable

public boolean isMovable()

Query whether this Polygon is movable.

Returns:

true iff this Polygon is movable.

getVertexCount

public int getVertexCount()

Get number of vertices in this Polygon.

Returns:

The number of vertices in this Polygon.

compareTo

public int compareTo(Variable arg0)

getDomain

public Domain getDomain()

Description copied from class: Variable

Get the domain of this Variable. Must be implemented by the ConstraintSolver developer, since getting the domain of a variable may be a non-trivial operation.

Specified by:

getDomain in class Variable

Returns:

The domain of the variable.

setDomain

public void setDomain(Domain d)

Description copied from class: Variable

Set the domain of this variable. Must be implemented by the ConstraintSolver developer, since setting the domain of a variable may be a non-trivial operation.

Specified by:

setDomain in class Variable

Parameters:

d - The domain of the variable.

setDomain

public void setDomain(Vec2... verts)

Set the domain of this Polygon, its vertices.

Parameters:

verts - The vertices of this Polygon.

toString

public java.lang.String toString()

Description copied from class: Variable

Get a String representation of this Variable.

Specified by:

toString in class Variable

Returns:

A String representation of this Variable.

getOrientation

public float getOrientation()

Get the orientation of this polygon (in radians).

Returns:

The orientation of this polygon (in radians).

setOrientation

public void setOrientation(float or)

Set the orientation of this polygon (in radians).

Parameters:

or - The orientation of this polygon (in radians).

getSupport

public Vec2 getSupport(Vec2 dir)

getPosition

public Vec2 getPosition()

Get the reference position of this Polygon.

Returns:

The reference position of this Polygon.

setPosition

public void setPosition(Vec2 position)

Set the reference position of this Polygon.

Parameters:

position - The reference position of this Polygon.

getFullSpaceRepresentation

public java.util.Vector<Vec2> getFullSpaceRepresentation()
