public static interface Multiset.Entry<E>
Multiset.entrySet()method returns a view of the multiset whose elements are of this class. A multiset implementation may return Entry instances that are either live "read-through" views to the Multiset, or immutable snapshots. Note that this type is unrelated to the similarly-named type
|Modifier and Type||Method and Description|
Indicates whether some other object is "equal to" this one.
Returns the count of the associated element in the underlying multiset.
Returns the multiset element corresponding to this entry.
Returns a hash code value for the object.
Returns the canonical string representation of this entry, defined as follows.
equals method implements an equivalence relation
on non-null object references:
trueif and only if
y, multiple invocations of
trueor consistently return
false, provided no information used in
equalscomparisons on the objects is modified.
equals method for class
the most discriminating possible equivalence relation on objects;
that is, for any non-null reference values
y, this method returns
true if and only
y refer to the same object
x == y has the value
Note that it is generally necessary to override the
method whenever this method is overridden, so as to maintain the
general contract for the
hashCode method, which states
that equal objects must have equal hash codes.
true if the given object is also a multiset entry and
the two entries represent the same element and count. That is, two
b are equal if:
Objects.equal(a.getElement(), b.getElement()) && a.getCount() == b.getCount()
The general contract of
hashCodemethod must consistently return the same integer, provided no information used in
equalscomparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
equals(Object)method, then calling the
hashCodemethod on each of the two objects must produce the same integer result.
Object.equals(java.lang.Object)method, then calling the
hashCodemethod on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
As much as is reasonably practical, the hashCode method defined by
Object does return distinct integers for distinct
objects. (This is typically implemented by converting the internal
address of the object into an integer, but this implementation
technique is not required by the
JavaTM programming language.)
The hash code of a multiset entry for element
count is defined as:
((element == null) ? 0 : element.hashCode()) ^ count
" x "(space, letter x, space), followed by the count.
