Method Details

equals

public boolean equals(Object o)

Description copied from interface: ReadOnlySet

Compares the specified object with this set for equality.

Returns true if the given object is also a read-only set and the two sets contain the same elements, ignoring the sequence of the elements.

Implementations of this method should use ReadOnlySet.setEquals(org.jhotdraw8.icollection.readonly.ReadOnlySet<E>, java.lang.Object).

Specified by:

equals in interface ReadOnlySet<E>

Overrides:

equals in class Object

Parameters:

o - an object

Returns:

true if the object is equal to this map

hashCode

public int hashCode()

Description copied from interface: ReadOnlySet

Returns the hash code value for this set. The hash code is the sum of the hash code of its elements.

Implementations of this method should use ReadOnlySet.iteratorToHashCode(java.util.Iterator<E>).

Specified by:

hashCode in interface ReadOnlySet<E>

Overrides:

hashCode in class Object

Returns:

the hash code value for this set
