Class MCRNormalizer

  org.mycore.common.MCRNormalizer

public class MCRNormalizer
extends Object

This class implements only static methods to normalize text values. Rules written as x>u .You can configure this normalization with three property values

• MCR.Metadata.Normalize.AddRule - add more rules to the default rule
• MCR.Metadata.Normalize.SetRule - replace the default rule
• MCR.Metadata.Normalize.DiacriticRule true (standard) | false - first rule, remove diacritics from letters
  Here you can see how decomposition works: http://www.icu-project.org/apiref/icu4j/com/ibm/icu/text/Normalizer.html
  These diacritics will be removed from letters when property is true:

Method Detail

normalizeString

public static final String normalizeString(String in)

This method replaces umlauts and other special characters of languages like german to normalized lowercase a-z characters.

Parameters:

in - the String to be normalized

Returns:

the normalized String in lower case.

normalizeString

public static final String normalizeString(String in,
                                           boolean reallyNormalize)

setDoNormalize

public static final void setDoNormalize(boolean value)

Activates or deactivates normalizing. Used in miless software to make indexing of scorm and searching possible

Parameters:

value - true normalize strings false do not normalize strings
