Field Detail

edgeCrossesIndicator

private double edgeCrossesIndicator

sum value for edge Crosses

---

additions

private int additions

counter for additions to the edgeCrossesIndicator

---

level

int level

the vertical level where the cell wrapper is inserted

---

gridPosition

int gridPosition

current position in the grid

---

priority

int priority

priority for movements to the barycenter

---

vertexView

VertexView vertexView

reference to the wrapped cell

Constructor Detail

SugiyamaLayoutAlgorithm.CellWrapper

SugiyamaLayoutAlgorithm.CellWrapper(int level,
                                    double edgeCrossesIndicator,
                                    VertexView vertexView)

creates an instance and memorizes the parameters

Method Detail

getVertexView

VertexView getVertexView()

returns the wrapped cell

---

resetEdgeCrossesIndicator

void resetEdgeCrossesIndicator()

resets the indicator for edge crosses to 0

---

getEdgeCrossesIndicator

double getEdgeCrossesIndicator()

retruns the average value for the edge crosses indicator for the wrapped cell

---

addToEdgeCrossesIndicator

void addToEdgeCrossesIndicator(double addValue)

Addes a value to the edge crosses indicator for the wrapped cell

---

getLevel

int getLevel()

gets the level of the wrapped cell

---

getGridPosition

int getGridPosition()

gets the grid position for the wrapped cell

---

setGridPosition

void setGridPosition(int pos)

Sets the grid position for the wrapped cell

---

incrementPriority

void incrementPriority()

increments the the priority of this cell wrapper. The priority was used by moving the cell to its barycenter.

---

getPriority

int getPriority()

returns the priority of this cell wrapper. The priority was used by moving the cell to its barycenter.

---

compareTo

public int compareTo(java.lang.Object compare)

Description copied from interface: java.lang.Comparable

Compares this object with another, and returns a numerical result based on the comparison. If the result is negative, this object sorts less than the other; if 0, the two are equal, and if positive, this object sorts greater than the other. To translate this into boolean, simply perform o1.compareTo(o2) <op> 0, where op is one of <, <=, =, !=, >, or >=.

You must make sure that the comparison is mutual, ie. sgn(x.compareTo(y)) == -sgn(y.compareTo(x)) (where sgn() is defined as -1, 0, or 1 based on the sign). This includes throwing an exception in either direction if the two are not comparable; hence, compareTo(null) should always throw an Exception.

You should also ensure transitivity, in two forms: x.compareTo(y) > 0 && y.compareTo(z) > 0 implies x.compareTo(z) > 0; and x.compareTo(y) == 0 implies x.compareTo(z) == y.compareTo(z).

Specified by:

compareTo in interface java.lang.Comparable
