Field Detail
lastKey
protected int lastKey(Code)
A holder for the keyCode which was last processed



mediator
protected InputModeMediator mediator(Code)
The InputModeMediator for the current input session



st
final protected SymbolTable st(Code)
Symbol table



symbolTableChars
final protected static char[] symbolTableChars(Code)
The number of symbol_table is designed to be 29 for 5x6 matrix, starting the selection at 12. But if you have more, the total must be under 36 for 6x6 matrix.





Method Detail
beginInput
public void beginInput(InputModeMediator mediator, String inputSubset, int constraints)(Code)
This method will be called before any input keys are passed to this InputMode to allow the InputMode to perform any needed initialization. A reference to the InputModeMediator which is currently managing the relationship between this InputMode and the input session is passed in. This reference can be used by this InputMode to commit text input as well as end the input session with this InputMode. The reference is only valid until this InputMode's endInput() method is called.
Parameters:
  constraints - text input constraints. The semantics of theconstraints value are defined in the TextField API.
Parameters:
  mediator - the InputModeMediator which is negotiating therelationship between this InputMode and the input session
Parameters:
  inputSubset - current input subset



commitPendingChar
protected boolean commitPendingChar()(Code)
Commit pending char true if the char has been committed otherwise false



completeInputMode
protected void completeInputMode(boolean commit)(Code)
Complete current input mode
Parameters:
  commit - true if the symbol has to be committed otherwise false



endInput
public void endInput()(Code)
Mark the end of this InputMode's processing. The only possible call to this InputMode after a call to endInput() is a call to beginInput() to begin a new input session.



getCommandName
public String getCommandName()(Code)
Returns the command name which will represent this InputMode to the user the locale-appropriate command name to represent this InputModeto the user



getDisplayable
public Displayable getDisplayable()(Code)
Symbol Input mode is represented by Symbol table implemented as canvas SymbolTable



getIsConstraintsMap
public boolean[][] getIsConstraintsMap()(Code)
Returns the map specifying this input mode is proper one for the particular pair of input subset and constraint. The form of the map is |ANY|EMAILADDR|NUMERIC|PHONENUMBER|URL|DECIMAL| --------------------------------------------------------------------- IS_FULLWIDTH_DIGITS |t|f| t|f | t|f | t|f |t|f| t|f | IS_FULLWIDTH_LATIN |t|f| t|f | t|f | t|f |t|f| t|f | IS_HALFWIDTH_KATAKANA |t|f| t|f | t|f | t|f |t|f| t|f | IS_HANJA |t|f| t|f | t|f | t|f |t|f| t|f | IS_KANJI |t|f| t|f | t|f | t|f |t|f| t|f | IS_LATIN |t|f| t|f | t|f | t|f |t|f| t|f | IS_LATIN_DIGITS |t|f| t|f | t|f | t|f |t|f| t|f | IS_SIMPLIFIED_HANZI |t|f| t|f | t|f | t|f |t|f| t|f | IS_TRADITIONAL_HANZI |t|f| t|f | t|f | t|f |t|f| t|f | MIDP_UPPERCASE_LATIN |t|f| t|f | t|f | t|f |t|f| t|f | MIDP_LOWERCASE_LATIN |t|f| t|f | t|f | t|f |t|f| t|f | NULL |t|f| t|f | t|f | t|f |t|f| t|f | input subset x constraint map



getMatchList
public String[] getMatchList()(Code)
Gets the possible string matches returns the set of options.



getName
public String getName()(Code)
Returns the display name which will represent this InputMode to the user, such as in a selection list or the softbutton bar. the locale-appropriate name to represent this InputModeto the user



getNextMatch
public String getNextMatch()(Code)
Return the next possible match for the key input processed thus far by this InputMode. A call to this method should be preceeded by a check of hasMoreMatches(). If the InputMode has more available matches for the given input, this method will return them one by one. a String representing the next available match to the keyinput thus far



getPendingChar
public char getPendingChar()(Code)
return the pending char used to bypass the asynchronous commit mechanism e.g. to immediately commit a char before moving the cursor return the pending char



hasDisplayable
public boolean hasDisplayable()(Code)
Returns true if input mode is using its own displayable, false ifinput mode does not require the speial displayable for its representation. For Symbol mode is represented by Symbol table canvas, so it returns true true if input mode is using its own displayable, otherwise false



hasMoreMatches
public boolean hasMoreMatches()(Code)
True, if after processing a key, there is more than one possible match to the input. If this method returns true, the getNextMatch() method can be called to return the value. true if after processing a key, there is more than the onepossible match to the given input



isSymbol
public static boolean isSymbol(char c)(Code)
Check if the char is the symbol from the symbol table
Parameters:
  c - char true if this char exists in the symbol table otherwise false.



processKey
public int processKey(int keyCode, boolean longPress)(Code)
Process the given key code as input. This method will return true if the key was processed successfully, false otherwise.
Parameters:
  keyCode - the keycode of the key which was input
Parameters:
  longPress - return true if it's long key press otherwise false true if the key was processed by this InputMode, falseotherwise.



supportsConstraints
public boolean supportsConstraints(int constraints)(Code)
This method is called to determine if this InputMode supports the given text input constraints. The semantics of the constraints value are defined in the javax.microedition.lcdui.TextField API. If this InputMode returns false, this InputMode must not be used to process key input for the selected text component.
Parameters:
  constraints - text input constraints. The semantics of theconstraints value are defined in the TextField API. true if this InputMode supports the given text componentconstraints, as defined in the MIDP TextField API



validateState
protected void validateState(boolean activeOperation)(Code)
This method will validate the state of this InputMode. If this is a check for an "active" operation, the TextInputMediator must be non-null or else this method will throw an IllegalStateException. If this is a check for an "inactive" operation, then the TextInputMediator should be null.
Parameters:
  activeOperation - true if any operation is active otherwise false.
