org.identityconnectors.common.EqualsHashCodeBuilder

public final class EqualsHashCodeBuilder
extends Object

Builder to simplify implementing the Object.equals(Object) and Object.hashCode() methods. This class uses ArrayList's implementation of AbstractList.equals(Object) and AbstractList.hashCode() and takes special care with deep arrays and Collection based objects.

Method Detail

append

public EqualsHashCodeBuilder append(Object object)

Appends the field value to an ArrayList to help facilitate equality testing.

Parameters:

object -

Returns:

Throws:

IllegalArgumentException - if a collection is passed since collections do not support value based equality. Sets, Lists, and Maps will work since they support value based equality.

appendBean

public void appendBean(Object obj)

This method will attempt to use reflection to get all the properties that make up the identity of the object. It will append(Object) all results from get methods that have a corresponding set method.

equals

public boolean equals(Object obj)

Determine equality based on the value of the members append to the builder.

Overrides:

equals in class Object

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

See Also:

Object.equals(java.lang.Object)

hashCode

public int hashCode()

Determine the hashcode based on the various members.

Overrides:

hashCode in class Object

Returns:

a hash code value for this object.

See Also:

Object.hashCode()

toString

public String toString()

Show the contents that make up the key.

Overrides:

toString in class Object

Returns:

a string representation of the object.
