Class NodeTree

java.lang.Object
  gnu.lists.AbstractSequence
      gnu.lists.TreeList
          gnu.xml.NodeTree

All Implemented Interfaces:

Consumable, Consumer, PositionConsumer, XConsumer, java.lang.Appendable

public class NodeTree
extends TreeList

Use to represent a Document or Document Fragment, in the XML DOM sense. More compact than traditional DOM, since it uses many fewer objects.

Method Detail

writePosition

public void writePosition(AbstractSequence seq,
                          int ipos)

Description copied from interface: PositionConsumer

Consume a single position pair. This PositionConsumer may assume the sequence does no reference management; i.e. that copyPos is trivial and releasePos is a no-op. If that is not the case, use consume(TreePosition) instead.

Specified by:

writePosition in interface PositionConsumer

Overrides:

writePosition in class TreeList

writeObject

public void writeObject(java.lang.Object v)

If v is a node, make a copy of it.

Specified by:

writeObject in interface Consumer

Overrides:

writeObject in class TreeList

nextPos

public int nextPos(int position)

Description copied from class: AbstractSequence

Return the next position following the argument. The new position has the isAfter property. The argument is implicitly released (as in releasePos). Returns 0 if we are already at end of file.

Overrides:

nextPos in class TreeList

make

public static NodeTree make()

getId

public int getId()

Get/create a new unique number.

stableCompare

public int stableCompare(AbstractSequence other)

Description copied from class: AbstractSequence

This is used for the XML concept of "document order".

Overrides:

stableCompare in class AbstractSequence

getIteratorAtPos

public SeqPosition getIteratorAtPos(int ipos)

Overrides:

getIteratorAtPos in class AbstractSequence

posNamespaceURI

public java.lang.String posNamespaceURI(int ipos)

posPrefix

public java.lang.String posPrefix(int ipos)

posLocalName

public java.lang.String posLocalName(int ipos)

posIsDefaultNamespace

public boolean posIsDefaultNamespace(int ipos,
                                     java.lang.String namespaceURI)

posLookupNamespaceURI

public java.lang.String posLookupNamespaceURI(int ipos,
                                              java.lang.String prefix)

posLookupPrefix

public java.lang.String posLookupPrefix(int ipos,
                                        java.lang.String namespaceURI)

posFirstChild

public int posFirstChild(int ipos)

posHasAttributes

public boolean posHasAttributes(int ipos)

typedValue

public java.lang.Object typedValue(int ipos)

Return the type-value of the node at the specified position.

posTarget

public java.lang.String posTarget(int ipos)

Get the target of a process-instruction.

toString

public java.lang.String toString()

Overrides:

toString in class AbstractSequence
