Constructor Detail

SimpleJavaDataBean

public SimpleJavaDataBean(Object bean)
                   throws IllegalArgumentException

Constructor for DataBeanAdapter.

Throws:

IllegalArgumentException

Method Detail

shallowClone

public IDataObject shallowClone()
                         throws UnsupportedOperationException

Description copied from interface: IDataObject

Shallow clone the object prior to being recusively "deep" cloned. This should return a new instance of the same class as the object suitable for receiving a series of setValue () calls to add copied properties from the original. Only state that would not be copied by the copying of all properties needs to be cloned by this method.

NOTE: Clients should not need to call this method: use DataObjects.deepClone(IDataObject) instead.

Specified by:

shallowClone in interface IDataObject

Overrides:

shallowClone in class AbstractDataObject

Returns:

A new object of the same type, with the same values as the original.

Throws:

UnsupportedOperationException - if the object or child object could not be cloned.

See Also:

DataObjects.deepClone(IDataObject)

dispose

public void dispose()

getBean

public Object getBean()

getTypeInfo

public TypeInfo getTypeInfo()

The default implementation uses TypeRegistry.peekTypeInfo(Class)to see whether any type info is registered for the class.

Specified by:

getTypeInfo in interface IDataObject

Specified by:

getTypeInfo in class AbstractDataObject

See Also:

TypeRegistry

getPropertyNames

public String[] getPropertyNames()

Description copied from interface: IDataBean

Databean's only have strings as their property names. This is a shortcut to get the property names for which getValue () would return a non-null value.

Specified by:

getPropertyNames in interface IDataBean

propertyIterator

public Iterator propertyIterator()

Description copied from interface: IDataObject

Get an iterator that scans over all currently defined properties.

Specified by:

propertyIterator in interface IDataObject

Returns:

An iterator that yields all defined property values (ie that would get a non-null result from IDataObject.getValue(Object)).

See Also:

IDataObject.getValue(Object), PropertyValueIterator

setValue

public void setValue(String name,
                     Object value,
                     int mode)

getDefaultValue

public Object getDefaultValue(String name)

isTransient

public boolean isTransient(Object name)

Description copied from interface: IDataObject

Test a property is transient (ie will not be preserved if the object is saved).

Specified by:

isTransient in interface IDataObject

Parameters:

name - The property name.

Returns:

boolean True if the property is transient.

setToDefaultValue

public void setToDefaultValue(String name)

setValue

public void setValue(Object name,
                     Object value)

Description copied from class: AbstractDataObject

Synonym for setValue (name, value, PERSISTENT_OVERRIDE).

Specified by:

setValue in interface IDataObject

Overrides:

setValue in class AbstractDataObject

Parameters:

name - The property "name" (may be any object).

value - The property value.

See Also:

IDataObject.setValue(Object, Object, int), IDataObject.getValue(Object), PropertyListener, PropertyEvent

setValue

public void setValue(Object name,
                     Object value,
                     int mode)

Description copied from interface: IDataObject

Set the value of a given property. If the object supports it, a property change event should be emitted.

Specified by:

setValue in interface IDataObject

Specified by:

setValue in class AbstractDataObject

Parameters:

name - A property name.

value - The new value. On most objects using null removes the property.

mode - The mode for the value. This is a bitwise OR of TRANSIENT and/or OVERRIDE. Using TRANSIENT specifies the value is to be marked transient (ie isTransient (name) will return true). Not all data object implementations support dynamic transience. OVERRIDE must be set if an existing value is to be overwritten: if not set and a value is already defined, then nothing is changed. The IDataObject.setValue (name, value) call corresponds to IDataBean.setValue (name, value, OVERRIDE).

See Also:

IDataObject.setValue(Object, Object)

getValue

public Object getValue(Object name)
                throws IllegalArgumentException

Description copied from interface: IDataObject

Get the value of a given property.

Specified by:

getValue in interface IDataObject

Parameters:

name - The property "name" (may be any object).

Returns:

the value of a given property or null if the property is not defined.

Throws:

IllegalArgumentException

See Also:

IDataObject.setValue(Object, Object), IDataObject.propertyIterator()

propertyChange

public void propertyChange(PropertyChangeEvent e)

Specified by:

propertyChange in interface PropertyChangeListener
