Class Grid

java.lang.Object

com.inubit.research.layouter.gridLayouter.Grid

public class Grid
extends java.lang.Object

2D-data structure where flowobjects are added to. afterwards a concrete x-y position can be determined by the location in the grid and the sizes of all contained elements.

public Grid()

initialises an empty grid

Method Detail

addRow

public void addRow(int rowIdx)

adds a new row at the given index. All objects in a row with index x >= rowIDx will be moved one row to the bottom and the Position will be propagated to them.

Parameters:

rowIdx -

getColCount

public int getColCount()

returns the current number of columns.

Returns:

addCol

public void addCol(int colIdx)

adds columns up to colIdx

Parameters:

colIdx -

setObject

public void setObject(int rowIdx,
                      int colIdx,
                      FlowObjectWrapper obj)

places an Object at the given position and informs the object of that position change.

Parameters:

rowIdx -

colIdx -

obj -

calculateSizes

public void calculateSizes()

calculates width,height for all grid-cells. needed so they can be applied with applyCoordinates.

calculatePositions

public void calculatePositions(int xOffset,
                               int yOffset)

calculates x,y position for all grid-cells. needed so they can be applied with applyCoordinates.

getGridHeight

public int getGridHeight()

gets the total height of this grid (sum of all rows)

Returns:

getGridWidth

public int getGridWidth()

gets the total width of this grid (sum of all cols)

Returns:

applyCoordinates

public void applyCoordinates(int xUL,
                             int yUL,
                             boolean vertical)

applies specific x,y coordinates to the underlying objects (wrapped FlowObjects)

Parameters:

vertical - invert x and y coordinates relative to the center of the grid (e.g. for vertical Pools)

interleave

public void interleave()

performs the interleaving (elimination of unnecessary rows)

getObject
