Constructor Detail

EasyScriptCompressedDecoder

public EasyScriptCompressedDecoder(SignatureProtocol signatureProtocol,
                                   int position,
                                   java.util.List<EasyScriptEventListener> listOfCoordinateReceiverListener)

Constructor, creates a new instance of EasyScriptEncoder class.

Parameters:

signatureProtocol - Is the current used signature protocol

position - the position of the first character of signature data in the entire stream. Follows the meta data.

listOfCoordinateReceiverListener - Interested listeners.

Method Detail

searchBinaryTree

protected int searchBinaryTree(java.util.List<java.lang.Boolean> stream)

This method parses the binary tree to find the value corresponding to a binary string

Parameters:

stream - a list of boolean values represents the binary stream.

Returns:

The integer value corresponding to the binary stream. If there weren't enough bits, returns -1, but remembers where it left off.

convertBodnarCharsToValue

protected int convertBodnarCharsToValue(java.lang.StringBuilder signature)
                                 throws SignatureInvalidException

This method reads characters from signature and puts them in 9-bit binary value It requires 2 or 3 characters and should only be given as many.

Parameters:

signature - String Represents the compressed signature

Returns:

the converted values of the characters or -1 if it could not be done...a third character may be required.

Throws:

SignatureInvalidException - Thrown in the event of a problem.

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.
