  • Method Details

    • getCapacity

      public long getCapacity()
      Returns the current available capacity in this array

    • sizeOf

      public long sizeOf()
      Returns the size of this big array in bytes.

    • get

      public T get(long index)
      Returns the element of this big array at specified index.
      Parameters:
      index - a position in this big array.
      Returns:
      the element of this big array at the specified position.

    • set

      public void set(long index, T value)
      Sets the element of this big array at specified index.
      Parameters:
      index - a position in this big array.

    • replace

      public boolean replace(long index, T value)
      Replaces the element of this big array at specified index.
      Parameters:
      index - a position in this big array.
      Returns:

    • ensureCapacity

      public void ensureCapacity(long length)
      Ensures this big array is at least the specified length. If the array is smaller, segments are added until the array is larger then the specified length.

    • fill

      public void fill(T value)
      Fills the entire big array with the specified value.

    • copyTo

      public void copyTo(long sourceIndex, ObjectBigArray<T> destination, long destinationIndex, long length)
      Copies this array, beginning at the specified sourceIndex, to the specified destinationIndex of the destination array. A subsequence of this array's components are copied to the destination array referenced by destination. The number of components copied is equal to the length argument. The components at positions sourceIndex through sourceIndex+length-1 in this array are copied into positions destinationIndex through destinationIndex+length-1, respectively, of the destination array.
