public static final int MATCHFLAG_POPWIN
```
    Match flag: Use pop-up window recognition.

    Constant Field Values
  - screenCount
```
public int screenCount
```
    Count of host screens.
  - areScreensAnalyzed
```
public boolean areScreensAnalyzed
```
    Flag indicating if the screens are analyzed so that "binary" search algorithm can be used.

```
public int matchFlags
```
    Flags used for matching screens.
  - useBinaryMatchMethod
```
public boolean useBinaryMatchMethod

```
public Hashtable<String,PhantomHostScreen> fastSearch
```
    The hash table for the screen groups instead of the binary search algorithm. The key for this array is a string where the first character is the screen group index followed by the screen matching data (ID_EXACT). The last screen group is not using this technique, so it is not included in this table.
  - screens
```
public Vector<PhantomHostScreen> screens
```
    The host screen array.
  - screensByName

```
public static final PhantomHostScreen dummyScreen
