Package gnu.xml

Class NamespaceBinding

java.lang.Object

gnu.xml.NamespaceBinding

All Implemented Interfaces:

Externalizable, Serializable

public final class NamespaceBinding
extends Object
implements Externalizable

A "namespace node" as a link in a linked list. The list may contain duplicates - i.e. multiple namespace bindings for the same prefix but (usually) different uris. In that case the first binding "wins". One reason for allowing duplicates it to allow sharing of the lists between a child and its parent element.

public static final NamespaceBinding predefinedXML

Constructor Details

NamespaceBinding

public NamespaceBinding(String prefix,
 String uri,
 NamespaceBinding next)

Method Details

getPrefix

public final String getPrefix()

Namespace prefix. An interned String. A default namespace declaration is represented using null.

setPrefix

public final void setPrefix(String prefix)

getUri

public final String getUri()

Namespace uri. An interned String. The value null "undeclares" any following namespaces with the same prefix; it corresponds to an empty uri as in the XML Namespaces 1.1 Candidate Recommendation.

setUri

public final void setUri(String uri)

getNext

public final NamespaceBinding getNext()

setNext

public final void setNext(NamespaceBinding next)

nconc

public static final NamespaceBinding nconc(NamespaceBinding list1,
 NamespaceBinding list2)

Chain the first list in front of the second list. (The name nconc comes from Common Lisp.)

resolve

public String resolve(String prefix)

Resolve a prefix.

Parameters:

prefix - an interned namespace prefix to search for.

Returns:

a uri or null if not bound

resolve

public String resolve(String prefix,
 NamespaceBinding fencePost)

Resolve a prefix, in the initial part of this list.

Parameters:

prefix - an interned namespace prefix to search for.

fencePost - only search this list until then.

Returns:

a uri or null if not bound

commonAncestor

public static NamespaceBinding commonAncestor(NamespaceBinding ns1,
 NamespaceBinding ns2)

reversePrefix

public NamespaceBinding reversePrefix(NamespaceBinding fencePost)

Reverse the chain, until a fencePost.

count

public int count(NamespaceBinding fencePost)

Return the number of bindings before the fencePost.

maybeAdd

public static NamespaceBinding maybeAdd(String prefix,
 String uri,
 NamespaceBinding bindings)

Append a new NamespaceBinding if not redundant.

toString

public String toString()

Return a String showing just a single namespace binding.

Overrides:

toString in class Object

toStringAll

public String toStringAll()

Return a String showing the full namespace binding list.
