  • Method Details

    • toByteArray

      <E> byte[] toByteArray(Iterable<E> iterable, int n, Function<E,Byte> byteMapper)
      The time complexity of this method is O(n) if the given iterable contains n elements.
      Type Parameters:
      E - the type of the elements of the given iterable
      Parameters:
      iterable - the mapped iterable, is considered to be empty when is null
      n -
      byteMapper -
      Returns:
      a new array with the first n bytes the given byteMapper maps from the elements of the given iterable, mapping null elements to 0
      Throws:
      RuntimeException - if the given n is negative or bigger than the size of the given iterable
      RuntimeException - if the given byteMapper is null

    • toDoubleArray

      <E> double[] toDoubleArray(Iterable<E> iterable, int n, ToDoubleFunction<E> doubleMapper)
      The time complexity of this method is O(n) if the given iterable contains n elements.
      Type Parameters:
      E - the type of the elements of the given iterable
      Parameters:
      iterable - the mapped iterable, is considered to be empty when is null
      n -
      doubleMapper -
      Returns:
      a new array with the first n doubles the given doubleMapper maps from the elements of the given iterable, mapping null elements to 0.0
      Throws:
      RuntimeException - if the given n is negative or bigger than the size of the given iterable
      RuntimeException - if the given doubleMapper is null

    • toIntArray

      <E> int[] toIntArray(Iterable<E> iterable, int n, ToIntFunction<E> intMapper)
      The time complexity of this method is O(n) if the given iterable contains n elements.
      Type Parameters:
      E - the type of the elements of the given iterable
      Parameters:
      iterable - the mapped iterable, is considered to be empty when is null
      n -
      intMapper -
      Returns:
      a new array with the first n ints the given intMapper maps from the elements of the given iterable, mapping null elements to 0
      Throws:
      RuntimeException - if the given n is negative or bigger than the size of the given iterable
      RuntimeException - if the given intMapper is null
