Examples with Norm2AllModes android.icu.impl.Norm2AllModes used on opensource projects

Example 1 with Norm2AllModes

use of android.icu.impl.Norm2AllModes in project j2objc by google.

the class Normalizer2 method getInstance.

/**
 * Returns a Normalizer2 instance which uses the specified data file
 * (an ICU data file if data=null, or else custom binary data)
 * and which composes or decomposes text according to the specified mode.
 * Returns an unmodifiable singleton instance.
 * <ul>
 * <li>Use data=null for data files that are part of ICU's own data.
 * <li>Use name="nfc" and COMPOSE/DECOMPOSE for Unicode standard NFC/NFD.
 * <li>Use name="nfkc" and COMPOSE/DECOMPOSE for Unicode standard NFKC/NFKD.
 * <li>Use name="nfkc_cf" and COMPOSE for Unicode standard NFKC_CF=NFKC_Casefold.
 * </ul>
 * If data!=null, then the binary data is read once and cached using the provided
 * name as the key.
 * If you know or expect the data to be cached already, you can use data!=null
 * for non-ICU data as well.
 * <p>Any {@link java.io.IOException} is wrapped into a {@link android.icu.util.ICUUncheckedIOException}.
 * @param data the binary, big-endian normalization (.nrm file) data, or null for ICU data
 * @param name "nfc" or "nfkc" or "nfkc_cf" or name of custom data file
 * @param mode normalization mode (compose or decompose etc.)
 * @return the requested Normalizer2, if successful
