Interface LArrayAccessor<P>

All Known Implementing Classes:
ListAccessor
public interface LArrayAccessor<P>
Provides access to the elements inside very large or small arrays. Designed to provide efficient access if the data is compressed or not. As a convenience, a function is provided for creating a copy of the elements.

  • Method Summary

    P
    getTemp(int index)
    Returns an instance of P which has the value of the element at 'index'.
    default boolean
    isEmpty()
    True if the array is empty
    default boolean

    True if the array has elements
    int
    size()
    Number of elements in the set

  • Method Details

    • getTemp

      P getTemp(int index)
      Returns an instance of P which has the value of the element at 'index'. Note that the accessor will own the data type which is returned and can modify it on the next call.

      This design is intended to be efficient when a massive array that's compressed and a very small array which is not compressed is used.

    • getCopy

      void getCopy(int index, P dst)
      Copies the element at 'index' into 'dst'. Only use if a copy is required.

    • copy

      void copy(P src, P dst)
      Copies src into dst

    • size

      int size()
      Number of elements in the set

    • isEmpty

      default boolean isEmpty()
      True if the array is empty

    • isNotEmpty

      default boolean isNotEmpty()
      True if the array has elements

    • getElementType

      Class<P> getElementType()
      Data type of element
