DynaBeanPropertyPointer

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

Method Detail

getBaseValue

public java.lang.Object getBaseValue()

Description copied from class: NodePointer

Returns 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

isContainer

public boolean isContainer()

This type of node is auxiliary.

Overrides:

isContainer in class NodePointer

getPropertyCount

public int getPropertyCount()

Number of the DP object's properties.

Specified by:

getPropertyCount in class PropertyPointer

getPropertyNames

public java.lang.String[] getPropertyNames()

Names of all properties, sorted alphabetically

Specified by:

getPropertyNames in class PropertyPointer

getPropertyName

public java.lang.String getPropertyName()

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

Specified by:

getPropertyName in class PropertyPointer

setPropertyName

public void setPropertyName(java.lang.String propertyName)

Select a property by name.

Specified by:

setPropertyName in class PropertyPointer

getPropertyIndex

public int getPropertyIndex()

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

Overrides:

getPropertyIndex in class PropertyPointer

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

getImmediateNode

public java.lang.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

isActualProperty

protected boolean isActualProperty()

Returns true if the bean has the currently selected property

Specified by:

isActualProperty in class PropertyPointer

isIndexedProperty

protected boolean isIndexedProperty()

setValue

public void setValue(java.lang.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

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

setValue

private void setValue(int index,
                      java.lang.Object value)

convert

private java.lang.Object convert(java.lang.Object value,
                                 boolean element)
