```
public abstract class HotSpot
extends java.lang.Object
```
Abstract class that is used to parse data of a line on the screen to create hot spots such as function keys (or other send keys) and links. Extending classes provides a way to parse a line on the screen and if a hot spot is found, call "addHotSpot" to create a new hot spot. This will create a new instance of the same class as the extending class.
This abstract class handles both parsing and identifying hot spots of a certain type as well as the actual drawing of them on screen and when they are activated (performing a function).

- text
```
public java.lang.String text
```

Constructor Detail
- HotSpot
```
public HotSpot()
```

Method Detail

equals
```
public boolean equals(java.lang.Object o)
```
Checks if one hot spot is equal to another.
Overrides:
equals in class java.lang.Object
Returns:
The equality flag not taking into account the active sstate.

hashCode
```
public int hashCode()
```
Gets the hash code.
Overrides:
hashCode in class java.lang.Object
Returns:
The hash code.

initialize

public abstract void initialize(java.lang.String setup,
                                boolean active)

Performs initialization from the setup data.

parse
```
public final java.util.List<HotSpot> parse(char[] line,
                                           java.util.List<HotSpot> hotSpots)
```
Performs parsing of the line just updated on the host screen. If this hot spot is successful, it should clear the data with the zero character. This method returns the same "hostSpots" list if there is no change, otherwise a new list.

continueChecking

public abstract boolean continueChecking(char[] line,
                                         char ch,
                                         int begin,
                                         int end)

Checks if it is OK to keep on checking.

check

public abstract int check(char[] line,
                          java.util.List<HotSpot> hotSpots,
                          int begin,
                          int end)

Checks if a hot spot is found. If it is, the position returned should be directly after the new hot spot.

onCreate
```
public void onCreate(HotSpot parent)
```
Called when a new hot spot has been instantiated.

addHotSpot

protected char[] addHotSpot(HotSpot hs,
                            char[] line,
                            java.util.List<HotSpot> hotSpots,
                            int x,
                            int width)

Adds a new hot spot of this same class (but a new instance) to the list.

isInside
```
public final boolean isInside(int xPos)
```
Checks if a position is inside the hot spot.

fillCharBackground

                               int cy)

Gets the background for drawing on the screen of the hot spot.

setTextColor

public void setTextColor(java.awt.Graphics g,
                         int xPos,
                         int yPos,
