| Tile | | public class Tile (Code) | | This class is used to represent an area of the viewport. It supports both
clipping areas, in viewport coordinates (which is why it uses integers), and
dirty area management.

| Field Summary | |
| public int | xmaxX
Start and end x tile coordinates. | | public int | ymaxY
Start and end y tile coordinates. |
| Constructor Summary | |
| public | Tile()
Default constructor. | | public | Tile(Tile t)
Copy constructor
Parameters:
t - the Tile to copy. | | public | Tile(int x, int y, int width, int height)
Constructor with the Tile's coordinates. |
| Method Summary | |
| public void | addSnapBox(Box b)
Adds the input Box to the tile, after snapping it to the integer grid.
Parameters:
b - the Box instance to snap to the grid and add to the tile. | | public void | addTile(Tile t)
Adds the input tile to this tile. | | public void | addTile(int tx, int ty, int tmaxX, int tmaxY)
Adds the input tile, defined by its x, y, maxX, maxY
values, to this tile. | | public boolean | isHit(Tile t)
true if the tile is hit by the input tile.
Parameters:
t - the tile to check. | | public void | setEmptyTile()
Sets this tile to be empty. | | public void | setTile(int x, int y, int width, int height)
Sets the tile's dimension and origin. | | public void | setTile(Tile t)
Sets this tile to the same x/y/maxX/maxY as t. | | public void | snapBox(Box b)
Sets the tile so that it snaps to the smallest pixel grid which completely
contains the input Box.
Parameters:
b - the Box instance to snap to the grid. | | public String | toString()
Debug. |
| xmaxX | | public int xmaxX(Code) | | Start and end x tile coordinates.
|
| ymaxY | | public int ymaxY(Code) | | Start and end y tile coordinates.
|
| Tile | | public Tile()(Code) | | Default constructor.
|
| Tile | | public Tile(Tile t)(Code) | | Copy constructor
Parameters:
t - the Tile to copy. Should not be null. |
| Tile | | public Tile(int x, int y, int width, int height)(Code) | | Constructor with the Tile's coordinates.
Parameters:
x - the tile's origin along the x-axis
Parameters:
y - the tile's origin along the y-axis
Parameters:
width - the tile's width
Parameters:
height - the tile's height |
| addSnapBox | | public void addSnapBox(Box b)(Code) | | Adds the input Box to the tile, after snapping it to the integer grid.
Parameters:
b - the Box instance to snap to the grid and add to the tile. Shouldnot be null. |
| addTile | | public void addTile(Tile t)(Code) | | Adds the input tile to this tile.
Parameters:
tile - the Tile to add. |
| addTile | | public void addTile(int tx, int ty, int tmaxX, int tmaxY)(Code) | | Adds the input tile, defined by its x, y, maxX, maxY
values, to this tile.
Parameters:
tx - the tile's x-axis origin
Parameters:
ty - the tile's y-axis origin
Parameters:
tmaxX - the tile's x-axis bottom right coordinate.
Parameters:
tmaxY - the tile's y-axis bottom right coordinate. |
| isHit | | public boolean isHit(Tile t)(Code) | | true if the tile is hit by the input tile.
Parameters:
t - the tile to check. Should not be null. |
| setEmptyTile | | public void setEmptyTile()(Code) | | Sets this tile to be empty. Actually, this sets the tile to a one pixel tile
in the top left corner of the integer coordinate grid (i.e, in Integer.MIN_VALUE,
Integer.MIN_VALUE). This tile will never intersect with any other tile.
|
| setTile | | public void setTile(int x, int y, int width, int height)(Code) | | Sets the tile's dimension and origin.
Parameters:
x - the tile's origin along the x-axis
Parameters:
y - the tile's origin along the y-axis
Parameters:
width - the tile's width
Parameters:
height - the tile's height |
| setTile | | public void setTile(Tile t)(Code) | | Sets this tile to the same x/y/maxX/maxY as t.
Parameters:
t - the Tile to copy. |
| snapBox | | public void snapBox(Box b)(Code) | | Sets the tile so that it snaps to the smallest pixel grid which completely
contains the input Box.
Parameters:
b - the Box instance to snap to the grid. If null, the tile is set to have all its values set to Integer.MIN_VALUE. |
