  • Method Details

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • isValid

      public boolean isValid()
      Description copied from interface: FSIterator
      Check if this iterator is valid.
      Returns:
      true if the iterator is valid.

    • get

      public T get()
      Description copied from interface: FSIterator
      Get the structure the iterator is pointing at.
      Returns:
      The structure the iterator is pointing at.

    • moveToNext

      public void moveToNext()
      Description copied from interface: FSIterator
      Advance the iterator. This may invalidate the iterator.
      See Also:

    • moveToPrevious

      public void moveToPrevious()
      Description copied from interface: FSIterator
      Move the iterator one element back. This may invalidate the iterator.
      See Also:

    • moveToFirst

      public void moveToFirst()
      Description copied from interface: FSIterator
      Move the iterator to the first element. The iterator will be valid iff the underlying collection is non-empty. Allowed even if the underlying indexes being iterated over were modified.
      See Also:

    • moveToLast

      public void moveToLast()
      Description copied from interface: FSIterator
      Move the iterator to the last element. The iterator will be valid iff the underlying collection is non-empty. Allowed even if the underlying indexes being iterated over were modified.
      See Also:

    • copy

      public FSIterator<T> copy()
      Description copied from interface: FSIterator
      Copy this iterator.
      Returns:
      A copy of this iterator, pointing at the same element.
      See Also:

    • moveTo

      public void moveTo(FeatureStructure fs)
      Description copied from interface: FSIterator
      Move the iterator to the first Feature Structure that is equal to fs. First means the earliest one occurring in the index, in case multiple FSs that are "equal" to fs are in the index. If no such feature structure exists in the underlying collection, set the iterator to the "insertion point" for fs, i.e., to a point where the current feature structure is greater than fs, and the previous one is less than fs.

      If the fs is greater than all of the entries in the index, the moveTo cannot set the iterator to an insertion point where the current feature structure is greater than fs, so it marks the iterator "invalid".

      If the underlying index is a bag index, no ordering is present, and the moveTo operation moves to the fs which is the same identical fs as the key. If no such fs is in the index, the iterator is marked invalid.

      Parameters:
      fs - The feature structure the iterator that supplies the comparison information. It must be of type T or a subtype of T.
