方法详细资料

initBaseSet

protected static void initBaseSet()

Initialise the module definitions.

initRightSet

protected static void initRightSet()

initLeftSet

protected static void initLeftSet()

getModule

public static Module getModule(java.lang.String key,
               int position)

Returns the module that represents the specified character.

参数:

key - The data character to get the encoding module for

position - The position of the data character, starts at 0

返回:

The module that encodes the given char

hasModule

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

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

返回:

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.

参数:

index - The index of the module required

返回:

The module at the specified index

isValid

public static boolean isValid(java.lang.String key)

Indicates whether the given character is valid for this barcode or not. This basically just checks to see whether the key is in the list of encoded characters.

参数:

key - The key to check for validity

返回:

True if the key is valid, false otherwise
