Method Detail

capability

public Capability capability()

Description copied from interface: Node

A Capability describing the User's current permissions for this Node.

Specified by:

capability in interface Node

Overrides:

capability in class NodeFilter

content

public NodeContent content()

Description copied from interface: Node

The Node's contents.

If the Capability does not provide read access, then this will return null.

Specified by:

content in interface Node

Overrides:

content in class NodeFilter

asAnchor

public AnchorNode asAnchor()

Description copied from interface: Node

An AnchorNode interface if this Node is an anchor, otherwise null.

Specified by:

asAnchor in interface Node

Overrides:

asAnchor in class NodeFilter

addTxnHandler

public void addTxnHandler(TxnHandler handler)

Description copied from interface: TxnMonitorable

Add a TxnHandler to be invoked when this object changes.

Specified by:

addTxnHandler in interface TxnMonitorable

Parameters:

Parameters:

handler - a TxnHandler that has previously been added.

notifyInsertAfter

protected void notifyInsertAfter(int index,
                                 java.lang.Object value)

notifyInsertBefore

protected void notifyInsertBefore(int index,
                                  java.lang.Object value)

notifyRemoveKey

protected void notifyRemoveKey(java.lang.Object key)

                                 int end)

notifyReplaceRange

protected void notifyReplaceRange(int start,
                                  int end,
                                  java.lang.Object seq)

notifySetValue

protected void notifySetValue(java.lang.Object property,

The number of properties contained in this Content object.

Specified by:

size in interface Content

properties

public java.util.Iterator properties()

Description copied from interface: Content

public Getter value(java.lang.Object obj)
             throws PropertyConstraintFailure

Description copied from interface: Content

A generic Getter for property values, given a property.

Will throw an exception if the property type is invalid, but not if the property is not available in this Node's content. This way, a value Getter can be established in anticipation of the addition of a property.

Specified by:

value in interface Content

Parameters:

obj - the Object that identifies this property

Throws:

PropertyConstraintFailure

getValue

public final java.lang.Object getValue(java.lang.Object idx)
                                throws PropertyConstraintFailure

Description copied from interface: Content

Access the property value, given a property.

Will throw an exception if the property type is invalid, but not if the property is not available in this Node's content. This way, a value Getter can be established in anticipation of the addition of a property.

Specified by:

getValue in interface Content

Parameters:

idx - the Object that identifies this property

Returns:

the value of the property

Throws:

PropertyConstraintFailure

invert
