Class Normalizer

java.lang.Object

org.jasypt.normalization.Normalizer

public final class Normalizer
extends java.lang.Object

Utility for the normalization of Unicode Strings to NFC form.

This class tries to use the java.text.Normalizer class in JDK 1.6 first and, if it the class is not found (Java version < 6), then it will use the ICU4J com.ibm.icu.text.Normalizer class (in this case, a ClassNotFoundException will be thrown if ICU4J is not present).

Since:

1.5

Method Detail

normalizeToNfc

public static java.lang.String normalizeToNfc(java.lang.String message)

Normalize Unicode-input message to NFC.

This algorithm will first try to normalize the input's UNICODE using icu4j's com.ibm.icu.text.Normalizer and, if it is not present at the classpath, will try to use java.text.Normalizer. If this is not present either (this class appeared in JavaSE 6), it will raise an exception.

Parameters:

message - the message to be normalized

Returns:

the result of the normalization operation

normalizeToNfc

public static char[] normalizeToNfc(char[] message)

Normalize Unicode-input message to NFC.

This algorithm will first try to normalize the input's UNICODE using icu4j's com.ibm.icu.text.Normalizer and, if it is not present at the classpath, will try to use java.text.Normalizer. If this is not present either (this class appeared in JavaSE 6), it will raise an exception.

Parameters:

message - the message to be normalized

Returns:

the result of the normalization operation

initializeIcu4j

static void initializeIcu4j()
                     throws java.lang.ClassNotFoundException

Throws:

java.lang.ClassNotFoundException

initializeJavaTextNormalizer

static void initializeJavaTextNormalizer()
                                  throws java.lang.ClassNotFoundException,
                                         java.lang.NoSuchMethodException,
                                         java.lang.NoSuchFieldException,
                                         java.lang.IllegalAccessException

Throws:
