Method Detail

ancestorAttribute

public int ancestorAttribute(int ipos, String namespace, 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 Path baseUriOfPos(int pos, boolean resolveRelative)

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

getAttribute

public int getAttribute(int parent, String namespaceURI, 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, String namespaceURI, 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

getId

public int getId()

Get/create a new unique number.

getIteratorAtPos

public SeqPosition getIteratorAtPos(int ipos)

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 {@code xml:id} are recognized has having the {@code is-id} property. Assumes makeIDtableIfNeeded has been called at soem point.
