    • type

      static io.deephaven.qst.type.PrimitiveVectorType<FloatVector,Float> type()

    • get

      float get(long index)
      Get the element of this FloatVector at offset index. If index is not within range [0, size()), will return the null float.
      Parameters:
      index - An offset into this FloatVector
      Returns:
      The element at the specified offset, or the null float

    • subVector

      FloatVector subVector(long fromIndexInclusive, long toIndexExclusive)
      Description copied from interface: Vector
      Get a Vector that represents a slice of this Vector.
      Specified by:
      subVector in interface Vector<FloatVector>
      Parameters:
      fromIndexInclusive - The first offset into this Vector to include in the result; if negative, the result will have a range of null values at offsets in [0, -fromIndexInclusive)
      toIndexExclusive - The first offset into this Vector to not include in the result; if larger than size(), the result will have a range of null values at the corresponding offsets
      Returns:
      The sub-Vector specified by [fromIndexInclusive, toIndexExclusive)

    • subVectorByPositions

      FloatVector subVectorByPositions(long[] positions)
      Description copied from interface: Vector
      Get a Vector that represents a set of offset positions in this Vector.
      Specified by:
      subVectorByPositions in interface Vector<FloatVector>
      Parameters:
      positions - The offsets to include; if not within [0, size()), the corresponding offset in the result will contain the appropriate null value
      Returns:
      The sub-Vector specified by positions

    • toArray

      float[] toArray()
      Description copied from interface: Vector
      Get an array representation of the elements of this Vector. Callers must not mutate the result, as implementations may choose to return their backing array in some cases.
      Specified by:
      toArray in interface Vector<FloatVector>
      Returns:
      An array representation of the elements of this Vector that must not be mutated

    • copyToArray

      float[] copyToArray()
      Description copied from interface: Vector
      Get an array representation of the elements of this Vector. Callers may freely mutate the result, as it is guaranteed to be freshly-allocated and belongs to the caller upon return.
      Specified by:
      copyToArray in interface Vector<FloatVector>
      Returns:
      An array representation of the elements of this Vector that may be freely mutated

    • getDirect

      FloatVector getDirect()
      Specified by:
      getDirect in interface Vector<FloatVector>
      Returns:
      A version of this Vector that is flattened out to only reference memory

    • iterator

      @FinalDefault default io.deephaven.engine.primitive.iterator.CloseablePrimitiveIteratorOfFloat iterator()
      Specified by:
      iterator in interface Iterable<Float>

    • iterator

      default io.deephaven.engine.primitive.iterator.CloseablePrimitiveIteratorOfFloat iterator(long fromIndexInclusive, long toIndexExclusive)
      Returns an iterator over a slice of this vector, with equivalent semantics to subVector(fromIndexInclusive, toIndexExclusive).iterator().
      Parameters:
      fromIndexInclusive - The first position to include
      toIndexExclusive - The first position after fromIndexInclusive to not include
      Returns:
      An iterator over the requested slice

      Get a String representation of a prefix of this Vector.
      Specified by:
      toString in interface Vector<FloatVector>
      Parameters:
