Constructor Details

PersistenceMemberElement

public PersistenceMemberElement()

Create new PersistenceMemberElement with no implementation. This constructor should only be used for cloning and archiving.

PersistenceMemberElement

protected PersistenceMemberElement(PersistenceMemberElement.Impl impl,
 PersistenceClassElement declaringClass)

Create new PersistenceMemberElement with the provided implementation. The implementation is responsible for storing all properties of the object.

Parameters:

impl - the implementation to use

declaringClass - the class to attach to

Method Details

getDeclaringClass

public PersistenceClassElement getDeclaringClass()

Get the declaring class.

Returns:

the class that owns this member element, or null if the element is not attached to any class

setDeclaringClass

public void setDeclaringClass(PersistenceClassElement declaringClass)

Set the declaring class of this member element. This method should only be used internally and for cloning and archiving.

Parameters:

declaringClass - the declaring class of this member element

equals

public boolean equals(Object obj)

Overrides PersistenceElement's equals method to add comparison of the name of the declaring class this persistence element. The method returns false if obj does not have a declaring class with the same name as this persistence element.

Overrides:

equals in class PersistenceElement

Parameters:

obj - the reference object with which to compare.

Returns:

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

hashCode

public int hashCode()

Overrides PersistenceElement's hashCode method to add the hashCode of this persistence element's declaring class.

Overrides:

hashCode in class PersistenceElement

Returns:

a hash code value for this object.
