Method Summary

void	__printOn(TextWriter out) Enabled: Prints as "sml`...`", where pretty printed XML appears between the backquotes
abstract Astro	build(AstroBuilder builder) Enabled: Used to convert from a Node tree to an Astro (eg, AST or Term) tree.
abstract ConstList	getChildNodes() Enabled: Modified to return an ConstList of Nodes rather than a NodeList.
abstract short	getNodeType() Enabled: A code representing the type of the underlying object, as defined above.
void	iterate(AssocFunc body) Enabled: A node iterates its children
Node	minimize() Enabled:
(package private) abstract Node[]	minimize(Node optLeft) Asks this Node to return a minimal form of the optional node to the left of itself and itself.
abstract void	prettyPrintOn(TextWriter out, boolean quasiFlag) Enabled: Prints pretty printed XML
boolean	supports(String feature, String version) Enabled: Tests whether the DOM implementation implements a specific feature and that feature is supported by this node.
abstract Object	welcome(Object visitor) Enabled: The classic visitor pattern from the patterns literature, except that we don't dispatch on the type of the node, but, for Elements, on a verb generated from the tag name.

Method Detail

getNodeType

public abstract short getNodeType()

Enabled: A code representing the type of the underlying object, as defined above.

getChildNodes

public abstract ConstList getChildNodes()

Enabled: Modified to return an ConstList of Nodes rather than a NodeList. The original documantation:

A NodeList that contains all children of this node. If there are no children, this is a NodeList containing no nodes. The content of the returned NodeList is "live" in the sense that, for instance, changes to the children of the node object that it was created from are immediately reflected in the nodes returned by the NodeList accessors; it is not a static snapshot of the content of the node. This is true for every NodeList , including the ones returned by the getElementsByTagName method.

iterate

public void iterate(AssocFunc body)

Enabled: A node iterates its children

Specified by:

iterate in interface Iteratable

welcome

public abstract Object welcome(Object visitor)

Enabled: The classic visitor pattern from the patterns literature, except that we don't dispatch on the type of the node, but, for Elements, on a verb generated from the tag name.

In order to call the visitor with generated names, we call the visitor with E.call().

supports

public boolean supports(String feature,
                        String version)

Enabled: Tests whether the DOM implementation implements a specific feature and that feature is supported by this node.

Parameters:

feature - The name of the feature to test. This is the same name which can be passed to the method hasFeature on DOMImplementation .

version - This is the version number of the feature to test. In Level 2, version 1, this is the string "2.0". If the version is not specified, supporting any version of the feature will cause the method to return true .

Returns:

Returns true if the specified feature is supported on this node, false otherwise.

Since:

DOM Level 2

__printOn

public void __printOn(TextWriter out)
               throws IOException

Enabled: Prints as "sml`...`", where pretty printed XML appears between the backquotes

IOException

prettyPrintOn

public abstract void prettyPrintOn(TextWriter out,
                                   boolean quasiFlag)
                            throws IOException

Enabled: Prints pretty printed XML

IOException

build

public abstract Astro build(AstroBuilder builder)

Enabled: Used to convert from a Node tree to an Astro (eg, AST or Term) tree.

minimize

abstract Node[] minimize(Node optLeft)

Asks this Node to return a minimal form of the optional node to the left of itself and itself.

If the node to the left is provided (ie, if 'optLeft' isn't null), then this node may safely assume that this provided sibling has already been minimized.

The minimization is much like XML canonicalization, but depends on an assumption specific to Minimal-XML: That for an Element that contains sub-Elements, all pure-whitespace Texts that it also contains may be gotten rid of.

The number of nodes returned cannot exceed the number examined. In other words, if 'optLeft' is null, only zero or one node may be returned. If 'optLeft' isn't null, the number returned may only be zero, one, or two.

Returns:

A list of nodes to replace 'optLeft' and itself.
