public AlphaCode()

Method Detail

toXdmMap

public static MapItem toXdmMap(String input)

Parse an AlphaCode into an XDM map

Parameters:

input - the input alphacode

Returns:

the resulting map

Throws:

IllegalArgumentException - if the input is not a valid AlphaCode

fromXdmMap

public static String fromXdmMap(MapItem map)

toSequenceType

public static SequenceType toSequenceType(String input,
                                          Configuration config)

Convert an AlphaCode to a SequenceType

Parameters:

input - the input alphacode

config - the Saxon Configuration (which must contain any user-defined types that are referenced in the Alphacode)

Returns:

the corresponding SequenceType

Throws:

IllegalArgumentException - if the input is not a valid AlphaCode

toItemType

public static ItemType toItemType(String input,
                                  Configuration config)

Convert an AlphaCode to an ItemType. The occurrence indicator of the alphacode may be omitted, or may be "1": any other value is treated as an error.

Parameters:

input - the input alphacode

config - the Saxon Configuration (which must contain any user-defined types that are referenced in the Alphacode)

Returns:

the corresponding SequenceType

Throws:

IllegalArgumentException - if the input is not a valid AlphaCode

fromItemType

public static String fromItemType(ItemType type)

fromSequenceType

public static String fromSequenceType(SequenceType type)

fromLexicalSequenceType

public static String fromLexicalSequenceType(XPathContext context,
                                             String input)
                                      throws XPathException

Throws:
