Class IterCollationIterator

java.lang.Object
com.ibm.icu.impl.coll.CollationIterator
com.ibm.icu.impl.coll.IterCollationIterator
Direct Known Subclasses:
FCDIterCollationIterator

public class IterCollationIterator extends CollationIterator
UCharIterator-based collation element and character iterator. Handles normalized 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
    • getOffset

      public int getOffset()
      Specified by:
      getOffset in class CollationIterator
    • 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 (cinvalid input: '<'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
    • forwardNumCodePoints

      protected void forwardNumCodePoints(int num)
      Specified by:
      forwardNumCodePoints in class CollationIterator
    • backwardNumCodePoints

      protected void backwardNumCodePoints(int num)
      Specified by:
      backwardNumCodePoints in class CollationIterator
