  org.joe_e.Struct

All Implemented Interfaces:

Selfless

public abstract class Struct
extends Object
implements Selfless

This abstract class contains implementations of the equals() and hashCode() methods that satisfy the Selfless interface. The provided equals() method computes equality of all fields using reflection.

Method Detail

equals

public final boolean equals(Object other)

Tests for equality with another object. An obect is equal to this one if it is of identical type and each field is equal for the two objects. The objects' fields are equal if both are null, or if their values return true for equals(). This implementation uses reflection to work for any subclass of Struct.

Overrides:

equals in class Object

Parameters:

other - candidate object

Returns:

true if it is equal to this object

See Also:

Object.hashCode(), HashMap

hashCode

public final int hashCode()

Calculates the hash code. This method will satisfy the contract of the hashCode method for any subclass of Struct. (two structs that are equal() structs will always have the same hashCode). The precise return value of this method is unspecified, and may change in future releases.

Specified by:

hashCode in interface Selfless

Overrides:

hashCode in class Object

Returns:

a hash value
