getValueObject

public abstract Object getValueObject()

Returns a single Object representing the value of the attribute as accurately as possible. Where possible the returned object's toString() method supplies an accurate (and localized where necessary/appropriate) string representation. This method is intended to provide easy, polymorphic read access to the IBA value itself. In other words, this does not include the value's context, constraints, and so forth, just the value itself.

Supported API: false

Specified by:

getValueObject in class AbstractValue

Returns:

Object

getAbstractDefinition

public abstract AbstractAttributeDefinition getAbstractDefinition()

Returns the AbstractAttributeDefinition associated with this value. This method is intended to provide easy, polymorphic read access to IBA definitions.

Supported API: false

Specified by:

getAbstractDefinition in class AbstractValue

Returns:

AbstractAttributeDefinition

equals

public boolean equals(Object obj)

Indicates whether the given object is equal to this object from a persistence perspective, by comparing the two objects ObjectIdentifiers. Changed or stale copies are still considered equal by this method. Delegates to PersistenceHelper.equals(Persistable,Object).

Warning: Certain core Windchill operations may depend upon equals being ObjectIdentifier-based. Changes to the default implementation should be done with care, if at all.

Supported API: false

Overrides:

equals in class AbstractValue

Parameters:

obj -

Returns:

boolean

hashCode

public int hashCode()

Returns a hash code for this object based upon its ObjectIdentifier. Delegates to PersistenceHelper.hashCode(Persistable).

Warning: Certain core Windchill operations may depend upon hashCode being ObjectIdentifier-based. Changes to the default implementation should be done with care, if at all.

Supported API: false

Overrides:

hashCode in class AbstractValue

Returns:

int
