siblings

public boolean siblings(String word,
                        int index)

Description copied from interface: Keyboard

Detects if char next to index is its sibling.

Specified by:

siblings in interface Keyboard

Parameters:

word - - string against which checks are performed.

index - - index of character to be tested.

Returns:

true if characters are siblings.

siblings

public boolean siblings(String word,
                        int index,
                        int isSiblingIndex)

Description copied from interface: Keyboard

Just as Keyboard.siblings(String, int), but it accepts index of second char that is a subject to test. This allows to detect patterns of keystrokes.

Specified by:

siblings in interface Keyboard

Parameters:

word - - string against which checks are performed.

index - - index of character to be tested.

isSiblingIndex - - index of second character to be tested.

Returns:

true if characters are siblings.

sequence

public int sequence(String word,
                    int start)

Description copied from interface: Keyboard

Detects sequence of keys in word. If Keyboard.siblings(String, int) returns true for 'index', Than this method will return at least '1' - indcating that after 'index' there is sequence of chars. Example:

  String word = "ASDFG";
  Keyboard.sequence(word,0) == word.length()-1;
 

Specified by:

sequence in interface Keyboard

Parameters:

word - - word in which keyboard is to search for keys sequence.

start - - start index of search.

Returns:

- number of characters in sequence
