Method Detail

getModule

public static Module getModule(java.lang.String key)

Returns the module that represents the specified character.

Parameters:

key - The data character to get the encoding module for

Returns:

The module that encodes the given char

getIndex

public static int getIndex(java.lang.String key)

Returns the index of the given character in the encoding tables. This is used when calculating the checksum.

Parameters:

key - The data character sequence to get the index for

Returns:

The index for the given key

hasModule

public static boolean hasModule(java.lang.String key,
                                boolean extendedMode)

Indicates whether the given key is represented in the default encoding table that this module factory contains.

Returns:

True if the key has a direct module encoding, false if not

getModuleForIndex

public static Module getModuleForIndex(int index)

Returns the encoded module at the given index position. This is used to get the encoded checksum character.

Parameters:

index - The index to get the module for

Returns:

The module at the specified index

getExtendedCharacter

public static java.lang.String getExtendedCharacter(char c)

Returns the string of characters from the standard encoding table that encode the given extended character set character.

Parameters:

c - The character from the extended ASCII set to encode

Returns:

The string of characters from the default Code 39 encoding table that represent the given character
