Method Detail

equals

public boolean equals(Object other)

Compares the specified object with this set for equality. Returns true if the specified object is also a set, the two sets have the same size, and every member of the specified set is contained in this set (or equivalently, every member of this set is contained in the specified set). This definition ensures that the equals method works properly across different implementations of the set interface.

Specified by:

equals in interface Collection<T>

Specified by:

equals in interface Set<T>

Overrides:

equals in class Object

Parameters:

other - object to be compared for equality with this set

Returns:

true if the specified object is equal to this set

hashCode

public int hashCode()

Returns the hash code value for this set. The hash code of a set is defined to be the sum of the hash codes of the elements in the set, where the hash code of a null element is defined to be zero. This ensures that s1.equals(s2) implies that s1.hashCode() == s2.hashCode() for any two sets s1 and s2, as required by the general contract of Object.hashCode().

Specified by:

hashCode in interface Collection<T>

Specified by:

hashCode in interface Set<T>

Overrides:

hashCode in class Object

Returns:

the hash code value for this set

emptySet

public static <TT> ImmutableSet<TT> emptySet()

setOf

public static <TT> ImmutableSet<TT> setOf(TT[] array)

setOf

public static <TT> ImmutableSet<TT> setOf(TT[] array,
                                          int length)
