Class NodeTree

java.lang.Object

gnu.lists.AbstractSequence<java.lang.Object>

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.

public NodeTree()

Method Detail

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<java.lang.Object>

getIteratorAtPos

public SeqPosition getIteratorAtPos(int ipos)

Overrides:

getIteratorAtPos in class AbstractSequence<java.lang.Object>

posNamespaceURI

                            java.lang.String namespaceURI)

posLookupNamespaceURI

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

posLookupPrefix

public java.lang.String posLookupPrefix(int ipos,

posFirstChild

public int posFirstChild(int ipos)

posHasAttributes

public boolean posHasAttributes(int ipos)

getAttribute

public int getAttribute(int parent,
               java.lang.String namespaceURI,
               java.lang.String localName)

Find named attribute.

Parameters:

namespaceURI - need not be interned, or null which matches any namespace

localName - need not be interned, or null which matches any local name

Returns:

attribute ipos or 0

getAttributeI

public int getAttributeI(int parent,
                java.lang.String namespaceURI,
                java.lang.String localName)

Find named attribute.

Parameters:

namespaceURI - an interned String or null which matches any namespace

localName - an interned String, or null which matches any local name

Returns:

attribute ipos or 0

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.

ancestorAttribute

                    java.lang.String namespace,
                    java.lang.String name)

Look for matching attribute in ancestor or self.

Parameters:

namespace - namespaceURI (interned) of required attribute

name - localName(interned) of required attribute

Returns:

attribute ipos or 0

baseUriOfPos

public gnu.kawa.io.Path baseUriOfPos(int pos,
                            boolean resolveRelative)

Return of the base-uri property, if known, of the node at pos.

toString

public java.lang.String toString()

Overrides:

toString in class AbstractSequence<java.lang.Object>

makeIDtableIfNeeded

public void makeIDtableIfNeeded()

lookupID

public int lookupID(java.lang.String name)

Look for an element with matching ID. Returns an element ipos, or -1 if not found. Since we don't do any validation, for now only attributes with the name xml:id are recognized has having the is-id property. Assumes makeIDtableIfNeeded has been called at soem point.
