Class UTF16CollationIterator

  • Direct Known Subclasses:
    FCDUTF16CollationIterator

    public class UTF16CollationIterator
    extends CollationIterator
    UTF-16 collation element and character iterator. Handles normalized UTF-16 text, with length or NUL-terminated. Unnormalized text is handled by a subclass.

      • resetToOffset

        public void resetToOffset​(int newOffset)
        Description copied from class: CollationIterator
        Resets the iterator state and sets the position to the specified offset. Subclasses must implement, and must call the parent class method, or CollationIterator.reset().
        Specified by:
        resetToOffset in class CollationIterator
      • setText

        public void setText​(boolean numeric,
                            java.lang.CharSequence s,
                            int p)
      • nextCodePoint

        public int nextCodePoint()
        Description copied from class: CollationIterator
        Returns the next code point (with post-increment). Public for identical-level comparison and for testing.
        Specified by:
        nextCodePoint in class CollationIterator
      • previousCodePoint

        public int previousCodePoint()
        Description copied from class: CollationIterator
        Returns the previous code point (with pre-decrement). Public for identical-level comparison and for testing.
        Specified by:
        previousCodePoint in class CollationIterator
      • handleNextCE32

        protected long handleNextCE32()
        Description copied from class: CollationIterator
        Returns the next code point and its local CE32 value. Returns Collation.FALLBACK_CE32 at the end of the text (c<0) or when c's CE32 value is to be looked up in the base data (fallback). The code point is used for fallbacks, context and implicit weights. It is ignored when the returned CE32 is not special (e.g., FFFD_CE32). Returns the code point in bits 63..32 (signed) and the CE32 in bits 31..0.
        Overrides:
        handleNextCE32 in class CollationIterator
      • handleGetTrailSurrogate

        protected char handleGetTrailSurrogate()
        Description copied from class: CollationIterator
        Called when handleNextCE32() returns a LEAD_SURROGATE_TAG for a lead surrogate code unit. Returns the trail surrogate in that case and advances past it, if a trail surrogate follows the lead surrogate. Otherwise returns any other code unit and does not advance.
        Overrides:
        handleGetTrailSurrogate in class CollationIterator
