position - Position in the string.

listOfCoordinateReceiverListener - A list of the CoordinateReceiver listeners.

Method Detail

decodePoint

protected Coordinate decodePoint(char[] ePoint)
                          throws SignatureInvalidException

This method attempts to take a four character point and decode it using the protocol's value tables.

Parameters:

ePoint - Array of four characters from the signature array to decode.

Returns:

Coordinate representing the decoded point in percentage of the screen (0->1).

Throws:

SignatureInvalidException - Thrown in the event there was a problem reading the point.

getSignatureProtocol

public SignatureProtocol getSignatureProtocol()

Gets the current signature protocol.

Returns:

the signatureProtocol

parseSignature

public void parseSignature(char ch)
                    throws SignatureInvalidException

This method parses the signature character by character to decode it.

Specified by:

parseSignature in interface EasyScriptDecoder

Parameters:

ch - A char read from the signature.

Throws:

SignatureInvalidException - Thrown in the event of a problem while parsing the signature.
