Constructor Detail

UnicodeToAnsel

public UnicodeToAnsel()

Creates a new instance and loads the MARC4J supplied Ansel/Unicode conversion tables based on the official LC tables. Loads in the generated class ReverseCodeTableGenerated which contains switch statements to lookup the MARC-8 encodings for given Unicode characters.

UnicodeToAnsel

public UnicodeToAnsel(boolean defaultCharsetOnlyPlusNCR)

Creates a new instance and loads the MARC4J supplied Ansel/Unicode conversion tables based on the official LC tables. Loads in the generated class ReverseCodeTableGenerated which contains switch statements to lookup the MARC-8 encodings for given Unicode characters.

UnicodeToAnsel

public UnicodeToAnsel(String pathname)

Constructs an instance with the specified pathname. Use this constructor to create an instance with a customized code table mapping. The mapping file should follow the structure of LC's XML MARC-8 to Unicode mapping (see: http://www.loc.gov/marc/specifications/codetables.xml).

UnicodeToAnsel

public UnicodeToAnsel(InputStream in)

Constructs an instance with the specified input stream. Use this constructor to create an instance with a customized code table mapping. The mapping file should follow the structure of LC's XML MARC-8 to Unicode mapping (see: http://www.loc.gov/marc/specifications/codetables.xml).

Method Detail

convert

public String convert(char[] data)

Converts UCS/Unicode data to MARC-8.

If there is no match for a Unicode character, it will be encoded as &#xXXXX; so that if the data is translated back into Unicode, the original data can be recreated.

Specified by:

convert in class CharConverter

Parameters:

data - - the UCS/Unicode data in an array of char

Returns:

String - the MARC-8 data
