Constructor Detail

ClassLabel

protected ClassLabel()

ClassLabels need an empty constructor for dynamic access. Subsequently, the init method must be called.

Method Detail

equals

public boolean equals(Object obj)

Any ClassLabel should ensure a natural ordering that is consistent with equals. Thus, if this.compareTo(o)==0, then this.equals(o) should be true.

Overrides:

equals in class Object

Parameters:

obj - an object to test for equality w.r.t. this ClassLabel

Returns:

true, if this==obj || this.compareTo(o)==0, false otherwise

toString

public abstract String toString()

Any ClassLabel requires a method to represent the label as a String. If ClassLabel a.equals((ClassLabel) b), then also a.toString().equals(b.toString()) should hold.

Overrides:

toString in class Object

See Also:

Object.toString()

hashCode

public int hashCode()

Returns the hashCode of the String-representation of this ClassLabel.

Overrides:

hashCode in class Object

See Also:

Object.hashCode()
