keys

public Set<Attributes.Key<?>> keys()

Returns set of keys stored in container.

Returns:

Set of Key objects.

newBuilder

public static Attributes.Builder newBuilder(Attributes base)

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object o)

Returns true if the given object is also a Attributes with an equal attribute values.

Note that if a stored values are mutable, it is possible for two objects to be considered equal at one point in time and not equal at another (due to concurrent mutation of attribute values).

Overrides:

equals in class Object

Parameters:

o - an object.

Returns:

true if the given object is a Attributes equal attributes.

hashCode

public int hashCode()

Returns a hash code for the attributes.

Note that if a stored values are mutable, it is possible for two objects to be considered equal at one point in time and not equal at another (due to concurrent mutation of attribute values).

Overrides:

hashCode in class Object

Returns:

a hash code for the attributes map.
