Method Detail

equals

public boolean equals(Object o)

Description copied from interface: Multiset.Entry

Returns true if the given object is also a multiset entry and the two entries represent the same element and count. More formally, two entries a and b are equal if:

  ((a.getElement() == null)
      ? (b.getElement() == null) : a.getElement().equals(b.getElement()))
    && (a.getCount() == b.getCount())

Specified by:

equals in interface Multiset.Entry<E>

Overrides:

equals in class Object

hashCode

public int hashCode()

Description copied from interface: Multiset.Entry

The hash code of a multiset entry e is defined to be:

  ((e.getElement() == null) ? 0 : e.getElement().hashCode())
    ^ e.getCount()

Specified by:

hashCode in interface Multiset.Entry<E>

Overrides:

hashCode in class Object

toString

public String toString()

Returns a string representation of this multiset entry. The string representation consists of the associated element if the associated count is one, and otherwise the associated element followed by the characters " x " (space, x and space) followed by the count. Elements and counts are converted to strings as by String.valueOf.

Overrides:

toString in class Object
