Constructor Details

DynaBeanPropertyPointer

public DynaBeanPropertyPointer(NodePointer parent,
 org.apache.commons.beanutils.DynaBean dynaBean)

Constructs a new DynaBeanPropertyPointer.

Parameters:

parent - pointer

dynaBean - pointed

Method Details

getBaseValue

public Object getBaseValue()

Description copied from class: NodePointer

Gets the value represented by the pointer before indexing. So, if the node represents an element of a collection, this method returns the collection itself.

Specified by:

getBaseValue in class NodePointer

Returns:

Object value

getImmediateNode

public Object getImmediateNode()

If index == WHOLE_COLLECTION, the value of the property, otherwise the value of the index'th element of the collection represented by the property. If the property is not a collection, index should be zero and the value will be the property itself.

Overrides:

getImmediateNode in class PropertyPointer

Returns:

Object

getPropertyCount

public int getPropertyCount()

Description copied from class: PropertyPointer

Count the number of properties represented.

Specified by:

getPropertyCount in class PropertyPointer

Returns:

int

getPropertyIndex

public int getPropertyIndex()

Index of the currently selected property in the list of all properties sorted alphabetically.

Overrides:

getPropertyIndex in class PropertyPointer

Returns:

int

getPropertyName

public String getPropertyName()

Returns the name of the currently selected property or "*" if none has been selected.

Specified by:

getPropertyName in class PropertyPointer

Returns:

String

getPropertyNames

public String[] getPropertyNames()

Description copied from class: PropertyPointer

Gets the names of the included properties.

Specified by:

getPropertyNames in class PropertyPointer

Returns:

String[]

isActualProperty

protected boolean isActualProperty()

Returns true if the bean has the currently selected property.

Specified by:

isActualProperty in class PropertyPointer

Returns:

boolean

isContainer

public boolean isContainer()

This type of node is auxiliary.

Overrides:

isContainer in class NodePointer

Returns:

true

isIndexedProperty

protected boolean isIndexedProperty()

Tests whether the property referenced is an indexed property.

Returns:

boolean

remove

public void remove()

Description copied from class: NodePointer

Remove the node of the object graph this pointer points to.

Overrides:

remove in class NodePointer

setPropertyIndex

public void setPropertyIndex(int index)

Index a property by its index in the list of all properties sorted alphabetically.

Overrides:

setPropertyIndex in class PropertyPointer

Parameters:

index - to set

setPropertyName

public void setPropertyName(String propertyName)

Select a property by name.

Specified by:

setPropertyName in class PropertyPointer

Parameters:

propertyName - to select

setValue

public void setValue(Object value)

If index == WHOLE_COLLECTION, change the value of the property, otherwise change the value of the index'th element of the collection represented by the property.

Specified by:

setValue in interface Pointer

Specified by:

setValue in class NodePointer

Parameters:

value - to set
