Method Detail

containsAll

public boolean containsAll(Collection<?> values)

Description copied from interface: Attribute

Indicates whether this attribute contains all the values in the collection.

Specified by:

containsAll in interface Attribute

Parameters:

values - The set of values for which to make the determination.

Returns:

true if this attribute contains all the values in the provided collection, or false if it does not contain at least one of them.

equals

public final boolean equals(Object o)

Description copied from interface: Attribute

Indicates whether the provided object is an attribute that is equal to this attribute. It will be considered equal if the attribute type, set of values, and set of options are equal.

Specified by:

equals in interface Attribute

Overrides:

equals in class Object

Parameters:

o - The object for which to make the determination.

Returns:

true if the provided object is an attribute that is equal to this attribute, or false if not.

hashCode

public int hashCode()

Description copied from interface: Attribute

Retrieves the hash code for this attribute. It will be calculated as the sum of the hash code for the attribute type and all values.

Specified by:

hashCode in interface Attribute

Overrides:

hashCode in class Object

Returns:

The hash code for this attribute.

isEmpty

public boolean isEmpty()

Returns true if this attribute contains no attribute values.

This implementation returns true if the Attribute.size() of this attribute is zero.

Specified by:

isEmpty in interface Attribute

Returns:

true if this attribute contains no attribute values.

isReal

public boolean isReal()

Description copied from interface: Attribute

Indicates whether this is a real attribute (persisted) rather than a virtual attribute (dynamically computed).

Specified by:

isReal in interface Attribute

Returns:

true if this is a real attribute.

toString

public final String toString()

Description copied from interface: Attribute

Retrieves a one-line string representation of this attribute.

Specified by:

toString in interface Attribute

Overrides:

toString in class Object

Returns:

A one-line string representation of this attribute.
