Class ImmutableMultiList.SetView

java.lang.Object
com.tangosol.util.WrapperCollections.AbstractWrapperCollection
com.tangosol.util.WrapperCollections.AbstractWrapperSet
com.tangosol.util.ImmutableMultiList.SetView

All Implemented Interfaces:

Iterable, Collection, Set

Enclosing class:

ImmutableMultiList

protected class ImmutableMultiList.SetView

extends WrapperCollections.AbstractWrapperSet

SetView exposes the underlying ImmutableMultiList through the Set interface, maintaining correct equals() and hashCode() semantics

Constructor Detail

ImmutableMultiList.SetView

protected ImmutableMultiList.SetView()

Create a SetView over this ImmutableMultiList.

Method Detail

equals

public boolean equals(Object o)

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

Specified by:

equals in interface Set

Overrides:

equals in class WrapperCollections.AbstractWrapperCollection

Parameters:

o - Object to be compared for equality with this set.

Returns:

true if the specified Object is equal to this set.

See Also:

Object.equals(Object), Set.equals(Object), List.equals(Object)

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 hashcode 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 the Object.hashCode method.

Specified by:

hashCode in interface Collection

Specified by:

hashCode in interface Set

Overrides:

hashCode in class WrapperCollections.AbstractWrapperCollection

Returns:

the hash code value for this set.
