Method Detail

get

public E get(int index)

Returns the object at the given index, provided the index is between 0 (inclusive) and size() (exclusive). If the index is < 0, then a left boundary object is returned. If the index is >= size(), a right boundary object is returned. The default boundary objects are both null, unless other objects are specified on construction.
