java.io.Serializable

public class EqualsBean
extends java.lang.Object
implements java.io.Serializable

Provides deep Bean equals() and hashCode() functionality for Java Beans.

It works on all read/write properties, recursively. It support all primitive types, Strings, Collections, bean-like objects and multi-dimensional arrays of any of them.

The hashcode is calculated by getting the hashcode of the Bean String representation.

EqualsBean

protected EqualsBean(java.lang.Class beanClass)

Default constructor.

To be used by classes extending EqualsBean only.

パラメータ:

beanClass - the class/interface to be used for property scanning.

EqualsBean

public EqualsBean(java.lang.Class beanClass,
                  java.lang.Object obj)

Creates a EqualsBean to be used in a delegation pattern.

For example:

public class Foo implements FooI { private EqualsBean _equalsBean; public Foo() { _equalsBean = new EqualsBean(FooI.class); } public boolean equals(Object obj) { return _equalsBean.beanEquals(obj); } public int hashCode() { return _equalsBean.beanHashCode(); } }

パラメータ:

beanClass - the class/interface to be used for property scanning.

obj - object bean to test equality.

メソッドの詳細

equals

public boolean equals(java.lang.Object obj)

Indicates whether some other object is "equal to" this object as defined by the Object equals() method.

To be used by classes extending EqualsBean. Although it works also for classes using EqualsBean in a delegation pattern, for correctness those classes should use the

オーバーライド:

クラス java.lang.Object 内の equals

パラメータ:

obj - he reference object with which to compare.

戻り値:

true if 'this' object is equal to the 'other' object.

beanEquals

public boolean beanEquals(java.lang.Object obj)

Indicates whether some other object is "equal to" the object passed in the constructor, as defined by the Object equals() method.

To be used by classes using EqualsBean in a delegation pattern,

パラメータ:

obj - he reference object with which to compare.

戻り値:

true if the object passed in the constructor is equal to the 'obj' object.

constructor.

hashCode

public int hashCode()

Returns the hashcode for this object.

It follows the contract defined by the Object hashCode() method.

The hashcode is calculated by getting the hashcode of the Bean String representation.
