Example 6 with CollationSettings

use of android.icu.impl.coll.CollationSettings in project j2objc by google.

the class RuleBasedCollator method setDecomposition.

/**
 * Sets the decomposition mode of this Collator.  Setting this
 * decomposition attribute with CANONICAL_DECOMPOSITION allows the
 * Collator to handle un-normalized text properly, producing the
 * same results as if the text were normalized. If
 * NO_DECOMPOSITION is set, it is the user's responsibility to
 * insure that all text is already in the appropriate form before
 * a comparison or before getting a CollationKey. Adjusting
 * decomposition mode allows the user to select between faster and
 * more complete collation behavior.
 *
 * <p>Since a great many of the world's languages do not require
 * text normalization, most locales set NO_DECOMPOSITION as the
 * default decomposition mode.
 *
 * The default decompositon mode for the Collator is
 * NO_DECOMPOSITON, unless specified otherwise by the locale used
 * to create the Collator.
 *
 * <p>See getDecomposition for a description of decomposition
 * mode.
 *
 * @param decomposition the new decomposition mode
 * @see #getDecomposition
 * @see #NO_DECOMPOSITION
 * @see #CANONICAL_DECOMPOSITION
 * @throws IllegalArgumentException If the given value is not a valid
 *            decomposition mode.

Example 8 with CollationSettings

use of android.icu.impl.coll.CollationSettings in project j2objc by google.

the class RuleBasedCollator method setAlternateHandlingShifted.

 * on <a href="http://www.unicode.org/unicode/reports/tr10/#Variable_Weighting">Variable Weighting</a>. This
 * attribute will only be effective when QUATERNARY strength is set. The default value for this mode is false,
 * corresponding to the NON_IGNORABLE mode in UCA. In the NON_IGNORABLE mode, the RuleBasedCollator treats all
 * the code points with non-ignorable primary weights in the same way. If the mode is set to true, the behavior
 * corresponds to SHIFTED defined in UCA, this causes code points with PRIMARY orders that are equal or below the
 * variable top value to be ignored in PRIMARY order and moved to the QUATERNARY order.
 *
 * @param shifted
 *            true if SHIFTED behavior for alternate handling is desired, false for the NON_IGNORABLE behavior.
 * @see #isAlternateHandlingShifted
