Interface ObservableFloatArray

All Superinterfaces:
Observable, ObservableArray<ObservableFloatArray>
public interface ObservableFloatArray
extends ObservableArray<ObservableFloatArray>
ObservableFloatArray is a float[] array that allows listeners to track changes when they occur. In order to track changes, the internal array is encapsulated and there is no direct access available from the outside. Bulk operations are supported but they always do a copy of the data range.
Since:
JavaFX 8.0

  • Method Details

    • copyTo

      void copyTo​(int srcIndex, float[] dest, int destIndex, int length)
      Copies specified portion of array into dest array. Throws the same exceptions as System.arraycopy() method.
      Parameters:
      srcIndex - starting position in the observable array
      dest - destination array
      destIndex - starting position in destination array
      length - length of portion to copy

    • copyTo

      void copyTo​(int srcIndex, ObservableFloatArray dest, int destIndex, int length)
      Copies specified portion of array into dest observable array. Throws the same exceptions as System.arraycopy() method.
      Parameters:
      srcIndex - starting position in the observable array
      dest - destination observable array

      length - length of portion to copy

    • get

      float get​(int index)
      Gets a single value of array. This is generally as fast as direct access to an array and eliminates necessity to make a copy of array.
      Parameters:
      index - index of element to get
      Returns:
      value at the given index
      Throws:
      ArrayIndexOutOfBoundsException - if index is outside array bounds

    • addAll

      void addAll​(float... elements)
      Appends given elements to the end of this array. Capacity is increased if necessary to match the new size of the data.
      Parameters:
      elements - elements to append

    • addAll

      void addAll​(ObservableFloatArray src)
      Appends content of a given observable array to the end of this array. Capacity is increased if necessary to match the new size of the data.
      Parameters:
      src - observable array with elements to append

    • addAll

      void addAll​(float[] src, int srcIndex, int length)
      Appends a portion of given array to the end of this array. Capacity is increased if necessary to match the new size of the data.
      Parameters:
      src - source array
      srcIndex - starting position in source array
      length - length of portion to append

    • addAll

      void addAll​(ObservableFloatArray src, int srcIndex, int length)
      Appends a portion of given observable array to the end of this array. Capacity is increased if necessary to match the new size of the data.
      Parameters:
      src - source observable array
      srcIndex - starting position in source array
      length - length of portion to append

    • setAll

      void setAll​(float... elements)
      Replaces this observable array content with given elements. Capacity is increased if necessary to match the new size of the data.
      Parameters:
      elements - elements to put into array content
      Throws:
      NullPointerException - if src is null

    • setAll

      void setAll​(float[] src, int srcIndex, int length)
      Replaces this observable array content with a copy of portion of a given array. Capacity is increased if necessary to match the new size of the data.
